USB Adapter with a USB hub

Hello all,
I received my USB adapter from Samsung today and am pleased to inform you that it works wonderfully with a USB hub. My hub has 4 slots on it and the tab was playing well with multiple USB devices being plugged in.

Really? I guess usb hub is needed to make things work? i had all kinds of issues. Mainly, not reading some usb drives, and memory reader. I just plugged the usb drive, directly into the usb adapter. The memory card reader was connected by standard usb to mini usb cable. That didn't work.
I got to try this.
Thanks.

No problem. I actually have not tried storage devices yet, only input devices. I posted on your other thread as well.
I have a feeling thumb drives may be having a problem if they are formatted in the FAT32 file system. I am going to try an NTFS drive and external hard drive and will let you know my results.
UPDATE: It appears I had it the other way around. I plugged in an NTFS drive to no avail, then formatted it to FAT32 and it worked.

FAT32 works great. NTFS is completely missing from stock kernels, it's in pershoot's "lib" extra modules archive on his kernels. However, I tried an NTFS drive using the extra module and it failed. (might require some manual mount magic???) It would take a lot more work to get FUSE working properly, and that's needed for the (vastly superior) ntfs-3g driver.

So does it work with external usb hard drives (both self powered and plug powered) of the sizes of 500GB and more?

what brand/type
what brand/type of usb hub do you have

If the hub is powered then the drive should work fine. You just can't use a usb powered drive without a power source

Ican't get mine to read my game controllers. Says something about high powered device. It won't let me read the message. When I tap it to make it bigger it just goes away. I am very frustrated. Can you get a fame controller to work? I used ps3.

PS3 controllers require a special driver. It may also require too much current since it tries to charge via USB. You'll need a powered hub if that is the case.
Gonna try my PS3 controller in a few minutes.
Edit: So far:
No excessive current errors from my PS3 controller - however mine has a fully charged battery because it's been plugged into a PS3 that has only been playing movies/videos for weeks. However button presses aren't recognized by anything. My guess is that if I dmesg I'll get an unrecognized device error. PS3 controllers are nonstandard.
However a Nyko AirFlo controller worked fine in SNES9x EX. It was semi-recognized by SNESoid - the keymap screen recognized something was being pressed, but games themselves wouldn't register presses.
Edit 2: PS3 controllers require the hid-sony kernel module to be loaded. This is included in pershoot's optional "lib" archive with his kernels. I had to hit the PS button to get it to turn on and start sending presses to the tab. No excessive current errors, but my controller was fully charged.

Thanks. But for some reason the ps3 and the x box controller worked for the xoom. I called samsung and they don't have any help for this issue yet. Can you get any external device to work for at least over fifty percent of what the adapter is meant to do? Did you get any error messages. I get high powered device connected. Then it say underneath that out could not connect. Device needs............. I cant read the rest. When I tap it to enlarge and read it disappears. Samsung can't figure out why that is happening either. Plz help.

Make sure the PS3 controller is fully charged before you connect it. If it isn't, it'll try to charge the battery and that's probably what sets off the overcurrent protection.
As to it working with the Xoom - I'd be VERY surprised if it worked with the Xoom when stock. Not so surprised about custom kernels, adding those modules is one of the first things people add, and the Xoom guys may have figured out module autoloading.

Thanks going to try now

wish i'd have read this before i bought it. i assumed it would since every other android tablet i have/had can power my external hds. pretty much makes it useless for me now as i was hoping to use it as external storage and for easy, quick file transfers. tf, xoom, and archos all work fine.

It works on a stock 3.1 build, it was one of those new features hyped at google i/o. I have both the European XOom and the Galaxy tab. The xoom copes fine with the ps3 and my other usb only non brand gamepad. The galaxy tab give me the hipower usb device error.

For SNESoid, you probably forgot to go into the other settings menu and turn on external input. The names may be off, but in addition to setting the key mappings, you have to turn on another option for it to see additional input devices, and then your gamepad will work

I had troubles reading an SD card with an old USB reader I had lying around. It was hit and miss.
Then I bought this SD card reader at Fry's for $4.99 and it works perfectly.

So, just to be clear, you are using a male A-A USB cable with one end plugged into the USB adapter on the GTab and the other end into one of the available USB ports in the hub, right?

Can some who knows alot about USB otg start a thread

There is a lot of interest about this spread out through all of the threads. Can someone with more knowledge than me on the subject post a "how to" on it? Just an idea to centralize the subject. Thanks

Search the threads, derp.
Searching the threads won't help. This information is scattered all over the place making search pretty much impossible. The ridiculously-obselete forum format doesn't help, either.
I did get mounting to work with the Stickmount app from the market. The multiple partitions on my external drive supposedly mount under /sdcard/usbstorage but they show as empty in any file managers.
Edit: Based on Stickmount's info the reason the drives show up empty is more than likely because I'm using an adapter instead of a cable. I'll update when my cable comes in the mail.

all I know is I can't wait for Bluetooth otg, my emulators with a bluetooth wiimote will make me a happy man lol

otg
hi all iv'e posted a bit about my knowledge of otg in different threads and thought id post what i know/figured out so far in this thread.
please correct me if you know any different.
the only difference between a usb cable & a otg cable/adapter is that the otg has pin 5 joined to pin 4 (this lets your kindle activate otg host mode). unfortunately most cables only have 4 cables attached (even if pin 5 is present in the connector) .
you can find an app called electrodroid in the market to see usb pin-out.
usb controller seems to be a good app to see which devices connect ok.
stick mount works well for me to mount usb drive.
tip's
download stickmount app, open and allow permission
turn off kindle & plug in otg cable connected to a powered hub (mine has a switch on the side, "bus or self", i set it on self) insert flash drive into hub.
then power on kindle when loaded the app stickmount should auto connect your flashdrive (there should be a popup) if not open up stickmount app and hit connect.
then you should see the popup.
open root explorer and goto sdcard you should see usb storage in there (for some reason on my 1st attempt to open root explorer it always shows as empty, just exit the reopen R/E).
?if you unplug otg cable without going into stickmount and disconnecting sometimes you can't remount without a reboot?
a mouse and keyboard should just work but iv'e also found that they also need to be inserted before booting up. my mac keyboard doesn't work at all but my mouse/keyboard combo ie. one dongle which both keyboard and mouse came with works fine
still playing with bluetooth. i can see it in usb controller app but can't switch it on yet, i think this is something hash is aware of and it needs something tweeking in the kernel.
everything seems to need the extra power of a powered hub. i did have my mouse working on its own once or twice but most of the time it needs powered hub.
here's a pic of my setup. hope this helps someone get it working as it's awesome.

I purchased USB otg cable -- ebay item #280820891599.
Installed stickmount and usb controller apps. Hash's Kernel #8. My generic 2gb USB stick is hot-pluggable, mounts at /sdcard/usbStorage/sda.
USB Controller indicates that my generic BT USB plugs (i have two of them) are "Connected USB devices" with the address 0001:0a12. So the system recognizes them, but what to do next?

i think i'm right in saying that hash needs to tweak the bt modules to allow us to activate it, mine shows the same but there is no way to toggle bluetooth yet.

Offtopic, but in regards to the bluetooth PS3 controller. I was searching but I couldn't find any guides on how to get the pair code for the device. Do you have to do it within Linux or can it be done within Windows?
On topic, I've purchased a bluetooth controller and I can't wait to play my emulators.

USB OTG
Hy,
Same here, unable to mount usb stick using USB OTG Cable without having external hub.
The USB OTG cable is working fine on my Galaxy Note.
I've tried several ROM on the kindle fire with kernel #8 but none of them make USB OTG work.
Anyone here can give a clue please ?
Thanks a lot

OTG through a HUB

Hey! So i managed my S2 to work with an OTG adapter. Now it recognizes Flash drives, USB mouse and keyboard as well. My problem is though, that i'd want to use both the mouse and the keyboard simultaneously, and later on my tablet as well.
I've got a USB hub which was pretty cheap i guess,
ht tp://itmedia.sk/item-images/other-usb_omega_hub4portSTARpowercapable/it6818_2.jpeg?nc=032
When i connect it to the OTG adapter it lights up, and if there's a flash drive attached to it when i plug it in, the phone recognizes the flashdrive without problem. As soon as i plug in a second flash drive, the light goes off from the HUB and both of the sticks get unrecognized. Also, the mouse nor the keyboard works through the HUB somehow..
I need to buy a specific hub with OTG support or a power hub perhaps? Could anyone help in this? I looked over google and stuff but people seemed to say different stuff at almost every site.. Thanks!!
My Galaxy S has stock 4.0.3 rom with the Syjah S2 4.1.4 Kernel

Oh well that's quite interesting. Then you're saying this piece of video could be fake perhaps?
Since i can post links yet, search for this on youtube: USB HUB Support On GALAXY S2
Check the very first video.

I'm convinced that the every phone can handle only one device connected at the same time.

Well, it surely doesn't seem that way, that's why i was asking, since it's possible.

Weird.... i got sgs2 and 4-port usb hub and when i connect 2 pendrives to hub and hub to phone everything works good (i see UsbDriveA and UsbDriveB). If your hub have dc input you can try connecting power supply to this hub. Maybe this hub isn't compatibile with your phone.

Second USB device

I tried connecting a USB keyboard using an USB OTG cable, but I didn't get it to work. The other USB port is in use by my external harddrive.
Is there a possibility to make the keyboard work?
Can immagine more people want to add a second USB device to their OUYA...

You'll need to buy a USB HUB (Get a powered one to future proof all your USB needs, you can get a USB 2.0 Hub pretty cheap). This will allow you to hook up at least 3 USB's to the OUYA. The Micro USB won't work for things such as hard drives or HID devices.
In the future, please use the search function before posting as this has been talked about in many other posts.

I have a 4-port hub and it works fine connecting 1 storage and 3 other usb devices

I had this issue where only one harddrive could be used and If you have a harddrive with 2 partitions ouya wont mount it. Luckily I found an app called usbotghelper which does all the above I mentioned plus read and write and ext3 support. I wish it would get submitted to the ouya store so I could use the paid version that will mount on startup.

OTG hardware in the fire stick?

Does anyone know if the Amazon fire TV stick has the OTG compatible hardware. I bought a Y OTG cable and it doesn't work . I was going to do a hardware root and see if I could get it working. But if doesn't even have the compatible hardware i'm not going to bother.

No one has been able to get anything working. I don't know whether it has the hardware or not, but I'm kind of doubting it, or it's not enabled at all in the OS.

I have looked at the PCB and it looks like only power is hooked up to the port the rest look grounded so there won't be any USB stuff for it

It's possible, but it's also pointless.
Connecting to your Fire TV stick is possible without using the cable, just by using adb.
ie: adb connect 192.168.0.103 (ip address of your Fire Stick)
