Hello Gents,
I purchased a USB OTG for my 7+ last week, all was working. the USB drives works, mouse works.
But this morning, when I tried to use the same mouse/usb drives. The tab does not seem to recognized the USB, I can see the LED on the USB blinks for a few moment and then turn off. Like it's getting power but then stop.
I tried the following.
1. reboot the tab. power on , power off. No go.
2. reboot from factory default ( yes it drives me nuts, but I did it anyway) Power Volume Up. Factory reset, data wipe. No go.
3. tried a new OTG USB cable, still does not work.
I had the Tab root before, but after the system reset, it gone back to stock firmware. The only thing I can think of is I did the latest Samsung Patch after my initial test.
When I look at the "dmesg"
s5p-ehci: detected XactErr len 0/8 retry
tspdrv: ImmVibeSPI_ForceOut_AmpEnable (1)
ImmVibeSPI_ForceOut_AMpDisable...
Does anyone have solution for this problem?
Thank
P.S. these are not the OEM Samsung USB cable. But they were working before.
Also, when I plug in an portable external HDD, it does say, High power device not supported.
hi,,,
try to connect all tools to usb otg hub first before you conect it to GTab. i mean if you want to connect a flash disk or a mouse, connect them to the usb otg hub first before connect it to GTab.
for hdd, you have to connect a power supply to usb otg to make it readable on GTab. i use my old nokia charger to power the usb otg hub device.
hope it help and sorry for my bad english.

edit : i use this device as usb otg hub

I have the same error but when I reboot my Tab, it's ok, before reboot I do not disconnect USB from my tab!You can try!
I just bought USB type A to Type A cable with hope to be able to view the share folder in my Asus TF700 via keyboard dock however I could not get it work. These are the tests:
1. use USB type A to type A cable connected between tf700 keyboard dock's USB port and my PC USB -> NOT working, unable to detect any storage folder
2. use portable HDD and connect it to the tf700 keyboard dock's USB port - NO PROBLEM. the TF700 is able to detect my USB storage
3. use the original USB charger (40 pin) cable from Asus and connect the other end (USB) to my PC. NO PROBLEM it works and this is how I transfer the files so far.
Does anyone know if the test 1 above should work?
thanks
I do not think it should work, because the USB port on our dock is a USB Host -- it's designed to make USB memory and external harddisks available to the system, not the other way around. That's why the 40-pin interface does that.
I am trying to connect my NVidia Sheild to a powered usb hub with no luck at this point.
Heres what I'm using:
Powered Hub
USB to Ethernet
OTG to USB
Male to Male USB
So I am taking the OTG to USB and connecting it to the Sheild OTG port. From there I have a Male to Male USB connecting the OTG to USB to the Powered usb hub. When I do this I can see that the Sheild's power light is orange which indicates to me that it is getting power and not acting as the USB Host for the Hub?
I did notice when I tried to use an air mouse directly with the OTG to USB it works as it should but not when it's connected to the powered usb hub instead, then nothing works (just charging). Also my ethernet adapter doesnt work via the powered usb hub or the OTG to USB.
BTW this whole physical setup worked just fine (plug and play) with both android MK808 and MK908. I was surprised that the Sheild isnt picking this up as well.
Can anyone tell me if I have incompatable hardware and if so what is compatable? Also I do not have ROOT access to the Sheild...yet, could that be the issue?
Many thanks in advance.

Think I need a mini HDMI to HDMI cable, a Micro USB OTG adapter and I should be sorted. Optionally could add a USB hub to allow me to use a USB to Ethernet adapter and a couple of other USB devices (such as a keyboard, mouse).

Hi!
I have quite strange problem with Arnova 10b G3 tablet.
My OTG works well, if i connect mouse or memorystick. But when i connect usb hub with OTG cable and then connect the same mouse or memorystick to hub, then nothing happens...
I tried two different usb hub with external power and one hub with non external power - all same.
HUB models : D-Link DUB-H4 and USM-124
App "Usb Host Controller" shows that Usb HUB is connected, but why i cannot see any device connected with hub?
In some googeling i founded something about hubenable.ko - when i type command lsmod then it isnt there. hubenable.ko is not also in folder modules.
Can you please help... I need it really to finish my carputer built...
ROM i use : kasty_oma_rk29cm101v121-arn10bg3-422-070-2G
