modding Atrix lapdock to charge other phones? - Atrix 4G Accessories

Ive since moved on from the atrix but kept the lapdock to see if i can use it for a hdmi monitor and charger. I now have the galaxy nexus and wanted try and use the lapdock with it. Im going to order the MHL adapter for the galaxy nexus to connect to the lapdock's hdmi with a female micro hdmi adapter. Ive read that the lapdock can receive HDMI input from other sources besides the atrix but will the lapdock accept HDMI source from a MHL adapter. Another problem is that in order for the Samsung MHL adapter to work it needs to be plugged in to a micro usb power source. I need to be able to use the micro usb from the lapdock if i want this set up to be portable.
i bought a micro usb extension and tried that but it doesnt charge galaxy nexus or Optimus P500. Unfortunately i sold my atrix before i got the cable so i cant test it with that but the micro usb extension charges all my phones fine when plugged into an AC adapter. So is it possible to mod the lapdock or micro hdmi cable to charge my other phones?

I can't speak for different phones made by different manufacturers (samsung, etc), but the atrix lapdock can be modified to work with other motorola weptop enabled phones. I am typing this on an atrix lapdock plugged into my Droid 4. I had to modify it when i bought it in order for it to work, but it was a simple 10 min job and it has been working well!
All I had to do was unscrew the cover of the hdmi/microusb ports, and flip over the connectors that were upside down for my use, and put it back together. A bit of shaving the plastic in the corners was necessary, but was not difficult. I am a happy user since this keyboard is a bit larger than the lapdock 100, and it was cheaper on craigslist than a lapdock 100.
Now I just need to see if anybody has managed to find any happy ways to hack/modify the atrix lapdock for greater functionality, like multitouch or scroll areas. If you have happened to see someone getting this to work, please do tell!

no need to mod!!! there are two powered usb ports on the back of the unit. when it senses hdmi, it turns on the usb ports and you can charge or power your usb device assuming 500ma is enough. not sure what it outputs, but it does charge a phone.

Where i can buy the lapdock charger?

you will not be able to plug in a USB peripheral (mouse, keyboard) directly into the phone. it will not work.
you can, however, purchase a +5V powered USB hub (that plugs into the wall), and use that to plug into the phone and plug your KB/mouse into the hub, and it should work. you can find such hubs at www.dealextreme.com
to further answer your question, USB-___USB converters will work as long as the converters have all four lines hooked up. many converters are 'power-only' where only the power/ground lines are connected and the other two lines (data) are not.
So if i buy an ordinary pc hub that connects to power and the plug usb-to-microusb, it will work?
Well let it alone, ill buy a Bluetooth keyboard, will spare time and cables and converters ahahha
The Micro USB plug must be OTG (USB ON THE GO) or your phone won't recognize the peripheral. Also the advice given was correct, the phone USB port can't provide power to a peripheral device and so you must use a powered hub in between the phone and the peripheral device.
A USB OTG has pin 5 and pin 4 tied together in the Micro USB connector end to tell the phone to invoke OTG mode.
Lordareon: yea... if you'd go the wired route, you'd need a powered USB hub, since the Atrix's micro-USB port doesn't work as a host port. It doesn't provide power to external devices.

micro female/male hdmi and usb for Lapdock

I bought these on ebay. The HDMI is short but worked but when I connect both cables to lapdock, the USB is not being recognized so the keyboard/mouse is not working. I want this just to act as an extension so I can use full lapdock abilities with cables. Any idea what's going on (cable charges on plug but does not charge on lapdock)? Maybe someone has better usb cables.

From your title I've been looking for these (or similar) cables for a long time and have been unsuccessful. However I have yet to try them.

i don't think it will work either way, tried a few things like this with no avail.
why wouldn't they? Cheap build quality that doesn't include the data wires? Hell I'll be willing to splice two cables together to get our desired effect, the only problem is that cords with a female micro usb are incredibly hard to come by
So that is what you think it is? No data on the usb cables.

the only reason that is my suspicion is because there are many "charging" products out there that don't really need data. Why there would be a need for such a small charging extension cable is beyond me, but it's the only solution I can think of, but I have no way of confirming or denying it either. The ebay descriptions seem to imply that the data wires are there, but we all know how reliable ebay can be...
Another idea I had was that it might be sensing the resistance in the cable, since, if I remember correctly, that was how some think/though the car dock puts the atrix into car mode without a magnet as is/was commonly used. Again these are just ideas.
Or the cable is just so poorly made that it's defective...I honestly have no clue
Has anyone got full lapdock capabilities using extension cables? I can only get the screen working and not the mouse and keyboard.
The HDMI extender was the hard one to find. There are other micro USB extenders out there, theoretically with all wires connected....
http://www.usbfirewire.com/uextendmicrob.html
Kind of makes me wish i hadn't hacked up my lapdock to work with the Otterbox
Where did you get your HDMI extender? I got mine from All4Cellular but it's quite short. Will have to get another HDMI one if the usb cable you recommended works.

The HDMI certainly looks like it may work but the reason I didn't buy that product from ebay a few weeks ago was because it was $50. Now miraculously, it's only $6. Maybe I'll get that if the USB cable I just bought that was suggested works a few posts back.

This micro usb extension cord explicitly states that all 5 wires are connected (compatible with droid bionic for the purpose of docking with a case on the phone):

The HDMI cable seems to work. On the lapdock, with just the HDMI cable hooked up, it functions like it was it's an entertainment center.
The USB cord will need to be modified a little bit. I can't get it to seat right on the USB jack of the dock. I'll need to shave it down a bit as it doesn't sit down snugly.

I ordered the USB cable and experience this same problem, though I am waiting for my hdmi parts to come in (by April 6th I should have all my parts...). The cable itself works flawlessly as a micro usb extension cable when connecting it to the computer.
again as mentioned in the other thread, you want to be careful with the 5v coming out that micro hdmi port. for connecting back to your phone would be no issue, as the phone charges using this voltage, but hooking the lapdocks micro usb up to a host device probably wont appreciate the 5v coming back up the cable, where normally the usb device would be pulling power from said host, not providing it.
one suggestion is to just clip the red wire inside your micro usb cable/adapter.
btw the adapters i use do fit snugly side by side, without modification.
I've been following this thread for a little while now, and I wanted to share something I found.
I was looking at the Motorola Travel Webtop adapter. And I was curious to see whether it could be tweaked to suite our needs. I naively thought/hoped that I could flip the connectors in the device to make a small adapter to connect the Atrix to newer Lapdocks. Unfortunately as you can see in the pictures below (sorry not enough posts to link to the pictures) the two connectors are connected via a PCB not wires or a ribbon cable. Although I still have high hopes that I can de-solder the HDMI and USB connectors, and use a small length of flat ribbon cable to connect them and then re-positions the connectors in the case, to build a micro adapter to use the Atrix on the newer Lapdocks. Should this fail this will at least prevent others from making the same mistake, and solve the mystery of what's really inside the Webtop Travel adapter.
Do any one know if this Micro HDMI Cable would work for Lapdock.

I have otterbox case for Atrix and don't want to Remove cover everytime to plug in Lapdock.

[Q] E4GT HDMI Mirroring

Has anyone gotten hdmi mirroring or any hdmi output on the epic 4g touch? I bought the micro usb to hdmi adapter plugged it in and it did nothing, also searched for mirroring apps with no luck. Samsung mentions hdmi output for it in there specs on the e4gt. Does anyone know anything about it or gotten it to work?

Did you plug power into the adapter??
Yeah, it works great for me. Does need AC power to drive the high def.
I ordered the adapter that was recommended on these forums; can't recall the name but I can find out.
Which adapter do you have?
As long as you use TouchWiz it will just work. It NEEDS an AC adapter to power it, I don't think USB port on a computer will work. If it's plugged into the wall, the TV, and the phone, then you may need to try a different TV or monitor.

I have a cable
I have a HDMI to MicroUSB that I bought at Target.
When I plug it in, it doesn't work. This is a scam considering it was $20 and my phone needs to be plugged in for anything to work... LOL so learn from my mistake and don't buy a single cable. You need to buy the thing where you can plug your phone into the HDMI and power all at once. Kinda like this one (I think. I'm not responsible if you buy it and its total crap)

MHL with USB OTG?

Has anyone found a MHL cable that also includes a USB OTG port? Samsung reportedly changed from a 5-pin configuration to an 11-pin configuration to allow MHL with USB Host mode simultaneously. Perhaps for a future Desktop Mode?
Has anyone been able to find one of these cables?
Just wanted to update, I believe I found the type of connector that I was looking for, but it is missing HDMI and it is sold out. This essentially could give you PC type connectivity on the S3.
http://www.mobilefun.com/35462-mobile-fun-connection-kit-for-samsung-galaxy-s3.htm
I think we still have a bit of a wait. What you found is essentially a USB OTG hub with some card readers built in. I seriously doubt this will pass through the pins for HDMI to work out of the usb port. We'll see something when this phone finally launches everywhere. It's not even out in the US officially yet
EDIT: Sorry, didn't see the article in the link in the OP. Man.. I might have to get me a GS3 now. I'm quite satisfied with the reasoning for a pin change. =)
Samsung sells 11 pin MHL adapters and USB female to Micro USB male adapters on their accessories page, but I'm not sure if you could piggy back the USB input into the charging port of the MHL cable. I don't see any all in one cables on their site, and the desktop dock is just micro usb/audio. I tried.. =(
Here's what I was looking at.
Old and mostly unrelated. See edit.
I happened to buy what looks exactly like that adapter today earlier at Micro Center. Now, I do have a Galaxy Nexus, but the USB OTG works great with keyboards/usb/mice/hubs; however, I cannot get it to simultaneously work with my MHL adapter. I understand the GS3 has a different pin layout though for MHL - my phone works with my MHL adapter correctly, but I didn't think it would have any change on the USB OTG. I'll most likely be breaking these apart and start tinkering. My goal is to show people how much of a full desktop-like experience I can provide from my phone, since so many people somehow think a GNex or GS3 are inferior to tablets, just because they're smaller... lol
Good luck finding information out on some kind of MHL/USB OTG setup. I'm just trying to provide any information I can from how my situation works with MHL/OTG, since I'm currently on the quest to achieve this myself.

I'm not really sure why people think they NEED MHL and USB OTG simultaneously to get a "desktop-like experience". You can already accomplish this with just a plain MHL cable and a bluetooth keyboard and mouse as was demonstrated in the Connectivity Demo video on youtube.
Edit: Actually I just remembered about portable hard drives. If you want to hook up a mouse, keyboard AND hard drive I wonder if you can plug all three into a powered USB hub connected to a bluetooth dongle. Hmm...
I'm looking for a dock with USB OTG, charging and MHL. Maybe some day.
I believe this is already capable. Everything I say here is purely speculative, but what I see is that Samsung moved to a 11-pin connector for MHL and the standard 5-pin is no longer functioning. To call it MHL, they probably have to use the same standards for data encoding... but they simply "moved" the pins.
I put "moved" in quotes because of the way in which a standard 4 pin USB cable works (or 5 pin for our case)... you have a +5V, Ground, Data + and Data - (one data to phone, one data from phone, carrying ALL data). Since our phones still sync via 5-pin cables, this means the 5 pins are still "hot" for data like all other phones. I am presuming, that for the 11-pin connector, Samsung simply added a few more data+ and data- connectors (much like having two or three USB ports on a normal computer) but consolidated the ground/5V reference. I could be wrong, but it would make sense.
Lets call the stock 5 pin data connectors (2 wires) USB1. This is where MHL is conventionally sent through and all sycing can be completed through, 5 pin cable or 11 pin cable. If samsung added two additional USB ports to the single connector, lets say MHL is now over USB2 (wires inaccessible to 5 pin connectors). This frees up bandwidth and COM ports on USB1 and USB3 to use for accessories like a USB hard drive and keyboard/mouse. On a 5 pin connector, however, only USB1 is accessible. The Samsung 11pin to 5pin MHL adapter simply moves the data+/- from USB2 to USB1 (standard 5 pin location), so with the adapter you are syncing/exporting video over USB2 on the phone with a standard 5pin cable.
My thinking is such: If you plug in the OEM 11pin MHL adapter, it will also have access to the standard 5pin USB1 connection. Since USB2 is used for MHL, you can then plug any OTG device into the micro USB connector on the MHL adapter to make use of it. The only problem here is power (or lack thereof). By plugging in a USB hub with a discrete power source, plugging this into the MHL adapter, and plugging in the USB device of choice into the HUB, you *SHOULD* be able to get simultaneous data and HDMI. This assumes they put the standard 5 pins to the connector on the side of the MHL adapter and only wired the HDMI to the USB2 area.
Alternatively, you *SHOULD* be able to plug the micro USB cable from the MHL adapter into a computer, and simultaneously be able to sync files while outputting HDMI video. It sort of just comes down to being able to provide power to the MHL adapter on the +5V pin while using the data pins to access the phone. As soon as I have my MHL I'll figure it out, but that could be a bit. If anybody has access to a pinout from a Samsung 11 pin micro USB that would be helpful too.
Again, just dreaming here. I don't know anything about this, but if I was the engineer at Samsung I would choose this over analog outputs like Apple used for their giant connector.

for me at least i already have several keyboards and mice ... none are bluetooth.
I'm looking for the cheapest option available.
I'm just hoping someone releases a cable with 4 plugs:
Male MHL - To Phone Obviously
Female MicroUSB: To plug in charger
Female HDMI - To Display
Female USB - To USB Device
That's all I want... should cost less than $2 to make, just sell it for $20 and I'd be happy.

hi v8bait, are you able to get data thru the micro usb port at the side of the 11-pin mhl adapter? i was thinking of using the motorola lapdock with my s3 thru the mhl adaptor (other then a micro hdmi male connector, the lapdock also has a micro usb male connector that apparently send out power as well as push keyboard/trackpad data upstream) - if it works, we can have an inexpensive "clambook"
Just to recap,
Will this we possible:
Official MHL adapter -> hdmi to monitor.
|
>OTG cable> Powered USB hub> USB keyboard & mouse.
In other words, the PC Experience with a keyboard and mouse.
Dont really want to spend the money to buy a Bluetooth keyboard and mouse when the USB ones can work just fine (theoretically).

I am also very interested in this exact thing. Using USB devices (multiple ones, e.g. plugging a powered USB hub into S III and then plugging them in) but also putting out S III video to HDMI.
However the other workaround is using AllShare Cast. In fact that is the route I'll likely go, because of the other unique advantages of AllShare Cast (i.e. using it for presentations to screens, etc.)
So: has anyone plugged a powered USB hub into S III and used multiple devices? Such as a keyboard and mouse?
I also want to use this S III more as a computer. the other perfect thing I wish I could buy would be a keyboard case, like the one available for iphone, so I can prop the S III up on a kickstand and use a real mini-QWERTY physical keyboard.

We're in the same boat; i want to use the s3 like a mini computer too. I think it'd be great for business travel, when i dont really need a laptop during the day but want something when i'm back in hotel room. I'd much rather use hotel TV instead of a laptop because that's what i am used to at home... pc hooked to TV.
I've been planning to use the allshare cast dongle too, but they dont seem to be available yet. I was thinking HDMI out with the allshare.. charging with the wireless charging kit and then keyboard and mouse with USB OTG. My logitech unifying receiver for keyboard/mouse works perfectly i just need the wireless charging and allshare dongle to be released.
For what it's worth I tried a powered USB hub and could not get it to work with the s3.

Wait so your saying you tried a (a) powered USB hub with a OTG cable connected to the phone or you tried a (b) powered USB hub connected with a OTG cable to the MHL adapter and then to the phone?
If it was (a) then there are some vids out there of ppl using powered USB hubs.

So has anyone received their Official MHL adapater and tried USB OTG?
Very interested in this.,,
I'm puzzled that there aren't any more postings about this kind of stuff. I was expecting the GS3 to be easy to use as a "PC" replacement but it seems no one besides us few wanted to do that ? A simple cable should have done it but I'd even be willing to shell out 40-50$ for a decent dock that would do just that

Me too.
But it is possible to get that this way working:
Code:
S3 -> Mobile Fun Connection Kit -> microusb -> HDTV Adapter TIP (5 to 11 Pin Converter) -> MHL HDMI adapter
|
-> USB -> keyboard etc.

Maybe I'm not reading these posts correctly but I am using an usb keyboard and a usb mouse on my S3 with no problems using these two accessories:

http://www.amazon.com/Micro-USB-OTG...UTF8&qid=1343846045&sr=1-3&keywords=otg+cable
Have my keyboard and mouse plugged into the usb hub and then the usb hub into my usb OTG cable which of course plugs into the S3. Everything's working on my end.

You are not reading it right.
they want to use the MHL adapter, too.
As far as i can tell, the MHL adapter needs to be in the phone, not a hub. it is all dictated (the output being OTG, or MHL) by the impedance of what is plugged in. It is an either or situation.
Perhaps with a firmware update they MIGHT be able to run both signals and split it.. but i doubt it.

Galaxy S III MHL Adapter Supports USB OTG--Work with GN?

The new MHL adapter for the Galaxy S III supports both HDMI and USB OTG simultaneously, according to this article:
http://www.gottabemobile.com/2012/06/29/galaxy-s-iii-new-mhl-connector-also-enables-usb-on-go/
I'm wondering if this means it could be used for USB OTG with a flash drive while charging the phone at the same time--something that's impossible with current adapters and cables. And does it also work with the Galaxy Nexus? Does anyone happen to have the adapter and a GN to test this?

My friend has an S3 and I know the 5 pin MHL adapter we use doesn't work with his because of the pin configuration, so I would assume if he can't get HDMI out using the 5pin, we won't be able to get HDMI out using the 11pin. Of course I am only guessing, but it makes sense to my mind.
I don't see how it could work, to use the HDMI out you need the charger cable plugged in to the MHL adaptor. So where would the OTG cable go?

Looks to me like the standard S3 MHL adapter has a micro USB "charging port". Could be that it could also accept an external drive. I don't have the phone or the cable yet, so I can't test. Maybe somebody who has both could post results?
it's not actually a charging port, it's a power port because apparently it needs more power to output HDMI, i.e. if you don't have the charger plugged in to the vacant port, no HDMI.
Samsung does sell a bunch of dual head micro usb to usb cables.... so maybe you need one of those and they sell this: http://www.samsung.com/us/mobile/cell-phones-accessories/ET-R205UBEGSTA which says it allows you connect drives, keyboards, etc to S3's....
Yeah those work, I actually use this one:
http://www.ebay.com/itm/Micro-USB-2...100-Note-i9220-Nexus-i9250-XOOM-/120894431890
or something similar, but you still can't use HDMI when you use those
you can however plug in keyboard, mouse, usb drive and anything else you want all at once which is cool
