USB Host mode

ADMIN EDIT:
adq is also a member here, direct link to his site about this:
http://adq.livejournal.com/95689.html
for dev's a patch is available to patch the kernel to enable this
It looks that one there are some guys that succeed to use the USB in host mode on an Android device ....
issue 738 on code.google http://code.google.com/p/android/iss...ummary%20Stars
Implementing the USB on the Go feature on a phone, will allow you to
conect to the phone:
- regular keyboards - imagine how easy you enter contacts, edit notes
and other text information into your phone when you go to home / work
and connect the keyboards from the computers you are using there.
- regular mice
- flash drivers, card readers, external hard drives, foto camera
- printers - so you can easily print the photos you make wit the built
in camera, and office documents you edit from the phone.
- scanners
- monitors (with a USB-to-VGA adapter, like the HTC Advantage X7510
does)
- WiFi cards
- USB ethernet cards - this would be an imensely great feature.
Because with propper software you can test an ethernet port (ping,
etc), even test UTP cables - like the expensive Fluke devices do. Just
imagine how convenient is to test a network without taking the laptop
with you and without buying expensive network testing tools.
- TV Tuners
- another phone that will stay in "slave mode"
- web camera - maybe it's a silly idea, but hey, why not?
- pen tablets
- USB hubs - so you will be able to connect all the above peripherals
to the phone in the same time.

This guy succeed to attache a real keyboard, a real mouse that is used as a trackball and a external USB storage device!!
Also he is using a battery USB hub to resolve the charging needs of some of the devices.....
how to create the cable , and some tests for Motorola Droid...
http://www.tombom.co.uk/blog/?p=124

Whoa, nice find. I didn't think this was even possible. I've been telling anyone who asked about it to keep dreaming. My bad.

yes..I also wanted to do this since I bought my first WM phone .... someone else tried this ?

instead of creating that patched cable do you think that a battery hub like this one that can change the gender of the USB, can be use instead ?
http://www.everfast.com.hk/catalog/usb-hub-battery-charger-usb-hub-4-ports-p-138.html
PS: it has also battery based charging capabilities

That's an interesting thought, although I don't have anything near the technical knowledge of this type of thing to say for sure. Your guess is as good as mine.

i'd say it should work with this. but i am afraid we'll have to wait until someone actually implements this somehow...
can someone pleeeease implement this somehow?

Keep in mind that If i read this correctly, this patch will disable usb device mode (i.e. wont be able to access the sd card as a mass storage device anymore and HTC Sync will be disabled as well).
Edit: At least for the time being. The dev seems keen on getting the device-mode/ host-mode drivers to cooperate.

Yeah, it shouldn't be too hard to implement a software switch.

On the other blog they propose this cables :

PS : I would like to buy one of this cables
PS2: I see on that e-bay link that this is already working on various linux powered mobile devices.

Hi, thanks for posting this here
Yeah, I'm just reading how the OMAP USB drivers implement the software switch just now to see how best to do it; right now looks like three drivers - two actually implementing the host/device mode, and one stub mediating which one is actually active.
I'm hoping to have something along these lines working next week.

thats great news mate will u posting your cabel guide to also this should be added i think to the custom roms (or at least a option the the kitchen tool)

There has been some progress:
http://adq.livejournal.com/
http://groups.google.com/group/android-kernel/browse_thread/thread/b871a27624f69b85

is it still not ready to be implemented even in experimental ROMs?

How should I install that? From Recovery? Like a Rom

is there any update on this? I would love to be able to read my SDCARD on my digital camer just by linking in with a usb cable

USB devices not detected by USB HOST
I am developing application to detect my printer by NOVO 7 Paladin(Android 4.0).
By USB HOST CONTROLLER application(which is available in market) the printer/mouse/keyboard is detected. But in my application(Written in java) these devices are not detected
With the reference of below link this application is developed
developer.android.com/guide/topics/usb/host.html
My Code Sample
mUsbManager = (UsbManager)getSystemService(Context.USB_SERVICE);
HashMap<String, UsbDevice> foundDevices = mUsbManager.getDeviceList();
Iterator<UsbDevice> iterator = foundDevices.values().iterator();
if (foundDevices.size()>0)
{String old = textv.getText().toString();
textv.setText(old +" foundDevices ");

This depends solely on which phone you have.
Also try going to forum.xda-developers.com and scroll down to your particular phone and search thier general forum for it, mainly because chances are someone already has asked or talked about this

I don't think any Android phone will support USB to Video adapters. Some android phones have hdmi or video out capabilities. But those types of USB to Video adapters need special drivers which I don't believe are available for Android OS.

I think that too, but there are drivers for linux and then android should make it work. I was just wondering if anyone tried.

here i found a list of the devices that are compatible with displaylink:
w w w.displaylink.com/shop/index.php?product=5
and in "download driver" are drivers for linux.
someone know if the driver for linux works for android ??
Pd: If a linux based router can: w w w.engadget.com/2009/05/18/displaylink-for-linux-turns-a-humble-wireless-router-into-a-beau/
why android cellphone or tablet cant.
also i found an app ($1,99) that allow to convert ipad screen into a new display for a computer through wireless, is there some app like that for android??

Android runs on top of a modified linux kernel, but it's not a true linux distro, so it can't run linux apps or drivers. Something would have to be written special. Maybe if you can run ubuntu off your device, you may be able to do something. What device do you have that has USB host?
Also, if its not USB 2, you may not have enough speeds to transfer. I think sending video output through usb would take a lot of processing power, which it may not be worthwhile with a phone.
What device do you have and exactly what are you trying to do... If I knew what you're trying to do, I might be able to help. I'm good with stuff like that.
You could maybe just get a DLNA adapter and wireless send video to a monitor or TV, instead. I'm not sure what you are exactly trying to get accompliched. give more details.

I bought a SmartQ t10, that still doesnt arrive, I bought it for the screen and battery, then i saw this adapter, so im seeing if can get video out.
I found a mailing list where a guy with a motorola droid (who managed to switch to USB host mode) trying to do this.
w w w.mailinglistarchive.com/html/[email protected]/2010-07/msg00073.html
according to what I understood you should enable the auxiliary output video and change the driver to operate with mobile device processor.

How to build displaylink driver for android
Displaylink is asic vender for USB-DISPLAY converter. It's is little slow, but expand your gadet example for android based equipment. So I modified the displaylink driver called udlfb for android.
How to build
- prepare android source code. I checked on beagleboard and android2.0
- extract and replace files with framework-core.tgz under framegework/base
- extract and replace files with kernel.tgz under kernel
- rebuild kernel and android
Description of tar archives
- framework-core.tgz
Import mouse and touch features support from android-x86 project . This is depend on android2.0 eclair
Touch features is following as:
Touch the right corner on and off touch feature.
[HOME] Touch the status bar
[MENU] Touch the status bar from left to right
[BACK] Touch status bat from right to left
- kernel.tgz
udlfb driver for android. Original udlfb driver source code is in latest linux driver/stagine/udlfb
Add double size frame buffer for pan_display
Add pan_display function
Make maximu resolution 1024x768. Original code support much more high resolution, but It cause crash under memory allocation.
Contents of tar archives
framework-core.tgz
==============================
Import usefule function from android-x86

drivers/video/Kconfig ->add configuration
drivers/video/Makefile ->add udlfb/Makefile
dotconfig -> .config example
drivers/video/udlfb/ -> driver
this will work??

If your phone does not have USB host mode you can modify your kernel to support it. Then it's a case of getting drivers, which may or may not be difficult.

Yes, i found that too, usb host for nexus one: sven.killig.de/android/N1/2.2/usb_host/
i guess that work for any device.
but I'm interested in that first run the driver already having a device with USB host, because is there more research about getting usb host or usb otg

Here is a android 1.6 driver from the opensource .
http://libdlo.freedesktop.org/wiki/
or
https://github.com/magoroku15/DisplayLink-driver-for-android
Any one know how to use it or update it to work on newer android ?

Gingerbread has very good compatibility mode so it "could" run there.

he simply wants to project his phone display on a lcd tv or a pc monitor.

many ppl with no hdmi output would love to stream by usb, it also allows to connect other usb devices which not supported with MHL.
usb 2.0 is fast enough to stream.

I've been researching the same kind of thing. I have an android head unit that I want to show everything I see on my roof screen but so far no luck. I have tried UBS to RCA and UBS to VGA adaptors but so far no luck. I even thought maybe something like android to android screen share like 'say' mobile-phone to android-tv-box and connect the tv-box in the car and share my Android head-unit to the tv-box but I can't find an app that works with doing that either.

[Q] Burn ISO to USB

Ok, this may be more of a general android question rather than device specific. I have several ISO files for various operating systems that I carry around on my memory card. Is there a way within Android ( likely similar to a dd command ) that I could burn the image to USB key? Im looking for a way to fix/repair computers on the go without needing to carry around my laptop ( Or download new / test releases and live boot them so to speak ).
Before you ask, yes I have a kernel that supports USB OTG and i can read/write to my usb key within my phone already. I was looking on the market for something similar to "live usb creator" but had no luck.
This is one of the only threads ive ever started and I do look around first. The information given could help many out if there is such a way The GS2 technically has more processing power than my n450 powered netbook It would be nice to actually utilize it as such.

From android OS I have no clue bro. However, you can try UnetBootin. This program will take an ISO and burn it to a USB drive that will boot. I do it all the time with Linux distros or Windows repair disks. Good luck

very interesting new App potential i see here
i could myself find this useful
to "burn" a bootable USB key to fix/boot repair a dead PC or something along the lines
so, the challenge will be to port over any of the Linux tools over to Android to get it working, shouldn't be too hard
unfortunately i do not have the spare time to get into this yet
but any DEV with free time wanting a fun challenge, this is an interesting one to play with

I'm looking into our available commands using terminal emulation So far its looking promising ( more like a cat command but still ).
If there are any Devs out there reading this, it would be a nice tool to have ;-)
In theory it should be very possible. Also, I was thinking about the possibility of porting over qtparted. Most of us techs have external USB to SATA/IDE adapters. Imagine pulling a laptop drive, wiping virii, repairing using scandisk, repartitioning borked disks, ect. Great ideas :-D This phone has more processing power than most netbooks in the market ( and actually better gpu capability too lol ). Why not put them to use !

I would love to see something like this. my pc hard drive has failed, New drive acquired but no win or ubuntu boot disks. If I could just put a boot on my spare 4gb micro ad... only have the phone for web access

hi
Yes I've wanted to do the same thing on a android tablet android tablets are missing out on such software iso burning and CD DVD writer tht connects too the tablet would be great the only thing stopping me from converting from Windows to android tablet with keyboard is this problem . Google would acutely make a killing if programmes and hardware like this was out for tablets .

Same here I have a tablet with that kernel that I can connect USB drives to but no burning software gutted

Try DroidDrive.
I'm going to test if it can boot iso's too.
Normally, it can boot img's.

Yes...I too need such apps like rufus on phone to create bootable pendrive
---------- Post added at 08:03 PM ---------- Previous post was at 08:00 PM ----------
Droid drive can only be used to boot pc from phone, but it can't be used to make pendrive bootable, and that is actually what we need.

From Terminal Emulator
dd if=/path/to/iso of=/block/device/id (for flash drive)
The only problem is that this method uses the entire flash drive.
Oh, and finding the block device id of your otg flash drive on android seems to be problematic.
Haven't tried it yet...
but it works on linux, and busybox
provides dd to android so...
Anyone have a way to find block device id for a usb otg flash drive?

ISO to USB on Play Store does this with no root

Am I missing something. I've been looking for hours and the app mentioned is very suspect and unreliable. I need create windows boot aswell whether from usb of phone itself.
Can't use root option app either due to SM-S908W as my phone.
Help pls!!

Any Apps for use the SG2 as a second monitor/display ?

Hello, sorry by advance if this have allready been posted.
I search an appliccation who let windows recognize the Samsung SgII as a second monitor,
( basically for DCS A10C, i can then use helios or any other software for directly dedicated some function of the cockpit in it )
There's Idisplay, but it seems not work well at all.
I have search on Android market, and find only remote desktop.

There is an app called iDisplay that is supposed to do this.

Thanks for your replies.
I have find some remote desktop ( basically you can use your pc using the phone and see exactly what is on your Windows screen, as Splashtop remote desktop )
What i search is a little bit different, basically something like iDisplay, where you can simply wire the phone on USB, and use your Android Phone as it was a second monitor.. This can let me use the phone display in addition of my PC monitor.
Maybe i ask to much to my SGSII . ( great phone in all aspect. )

Question Do you still need an official ASUS dock/hub for game genie mouse and keyboard?

Looking to buy either the ROG Phone 6 or Lenovo Legion and the main point against the ROG Phone is that I can't find the official dock. I know with the 3, you had to get an Asus branded hub. Is this still the case with the 6? Or will any USB-C hub now work for mouse and keyborad mapping?

You should be able to use 3rd party hubs with no issues. Bluetooth key-mose as well. ROG is miles better than Lenovo..

Yeah, I know the actual phone itself is much better. But previously, the keyboard and mouse remapping to touch screen features required an official Asus hub, otherwise it simply did not function. Everything else, like KB/M support and external displays worked with any old hub, but that specific feature was locked behind Asus hardware.
I don't even mind about the overpricing of those hubs, just can't find one anywhere anymore!

If we talk Duel 2, maybe, if we talk Y90, absolutely not.
Also he is refering to the ability to be able to keymap, which the answer is no. I am in process talking with some ASUS employees to make it happen tho. It looks promising.

Has anyone found a way to map keys without the official dock or with 3rd party USB hub?
Is there only one way to play with keyboard and mouse?

Hello.
First we need to enable "USB DEBUG" in the phone's developer options.
Now we need to install "ADB" on the computer and then plug the phone into the usb port and trust the device. With adb installed and the device trusted, we can now run the following command:
"adb shell setprop sys.asus.donglestate_GV_PD 2".
The property value can be either 2 or 3. This "identifies" the Asus Dock and tells the system that it is connected. Depending on the phone model, there may be a variation of the property, it can be: "vendor.asus.donglestate_GV_PD" or "sys.asus.donglestate_GV_PD", in my case the second option corresponds to my ROG PHONE 5S phone.
The command needs to be run again in case you shut down or restart your phone.
Contents of my script:
#!/bin/bash
bash -c "adb shell setprop 'sys.asus.donglestate_GV_PD' 2"
My phone has Android 12 and everything works normally.
It doesn't need root or anything like that, it just simulates what would likely happen when plugging in the Professional Dock.
Now you can use your dock or usb-c hub with keyboard and mouse and be happy.
This is also possible to do directly on the phone using "Local ADB" but it is a bit more complicated.
Comment if it worked or not.
Thanks.

When using a 3rd party hub for video out, how do you account for the different aspect ratios between the ROG phone and the display monitor?

In most cases, selecting to keep the source aspect ratio on the native resolution of the monitor will give the best picture quality as always. Most TV's will however just blast the picture up to max possible size - but should however still maintain the device aspect ratio. The resolution of ROG phones is just FHD (~1080p), so fits well within most displays/TV's on the market today..
