I have a Huawei u8160 running Psyke83's Cyanogenmod 7.2 14/8/2012.
I've recently been testing things on my recently activated OTG I've tried to connect a USB Portable HDD, However when I connect the HDD the LED flashes like it's reading/writing , dmesg notices it :
Code:
[INDENT]

that is what dmesg says directly after connecting.
and when I write lsusb on terminal emulator it returns :
Code:

one of them is always there,and another one is the USB Hub ,and another is the USB HDD
I already successfully mounted an NTFS Flash Drive (Fromatted using Minitool partition wizard,mounted using Paragon NTFS&HFS+) then the problem isn't the File System,when connecting the HDD Paragon NTFS&HFS+ doesn't even notice it
Does your hdd have an external power supply? I am assuming no. The n7 does not output enough power to spin up an external hdd. It can see it, but thats about it. Any hdd's that have power sources external from the phone will work fine. I use an external case that is externally powered with my 1Tb sata hdd. Works great. Its all about the power.

Hi Folks!
I'm a happy owner of a Galaxy Tab 10.1, and an EE engineer who frequently uses a small USB microscope while assembling boards.
I would be really happy to be able to use my Galaxy Tab as a lightweight portable screen for this microscope. This would be much more handy than having a bulky laptop stand in there.
So I've seen that the Galaxy Tab 10.1 has USB host capabilities. And after a quick verification, I've noted that the stock kernel has the uvcvideo driver builtin (the microscope is UVC compatible, actually it's a Logitech C310 hardware with added optics).
Seems like everything is in place to make it work. However when I plug the device in, I get an unrecognized USB device message popping up.
Here's the output from dmesg:

[email protected]:/ $ dmesg
Then it goes on and on with the 'new device [...] unable to enumerate' messages until I unplug it.
The device is found, and early init seems to go through (VID/PID are correct) but it doesn't seem to make it to the uvcvideo driver (or the driver is rejecting it, I don't know).
I am not very savvy as regards to linux's USB stack (though I know my way around linux, having cross compiled it, and tweaked it several times for boards I design), so I'm a bit lost as to what I could further investigate to pinpoint the issue.
I am certain that uvcvideo is present (dmesg shows 'usbcore: registered new interface driver uvcvideo' after boot).
Things works fine when I plug in a USB flash drive.
Things works fine too when I plug the microscope to my linux desktop (through uvcvideo).
Any idea or advices would be greatly appreciated!
Thanks,
Theo

Hi tbeauchant,
I am also looking for same , till now i didn't get any success but after going through with the code , i have seen that samsung have disable the feature of detecting a few device , in my case it says , unkown usb device and
dmesg says :: device ######(product id) ######(vendor id) not supported ,
did you get any success or any approch which you will follow.
Hi,
I just briked my TF201. I have only the Asus screen and the "The device is Unloked." notification.
If I restart my TF201 and hold vol up and power, on my Linux I found it like:
Code:
usb 1-5: new high-speed USB device number 6 using ehci-pci
usb 1-5: New USB device found, idVendor=0955, idProduct=7330
usb 1-5: New USB device strings: Mfr=1, Product=2, SerialNumber=0
usb 1-5: Product: APX
usb 1-5: Manufacturer: NVIDIA Corp.
mtp-probe: checking bus 1, device 6: "/sys/devices/pci0000:00/0000:00:02.1/usb1/1-5"
mtp-probe: bus: 1, device: 6 was not an MTP device
The TF is reconise under Windows too with the APX driver.
So I think I can use nvflash.
My question is there is any solution to unbrike my TF201 by using old TWRP bakup ? (I have the original configuration too)
Regards
Totorux
Your nandroid will only help if you can get to twrp. You should've used NVflash to generate the blobs, without thosr blobs NVflash will not help you

Sorry to say, but as you don't have the nvflash back up files APX mode is of no use to you, try buying a second hand motherboard of eBay and replacing it

Hello,
I tested with three different REDMI 3 devices and three different rom versions and have the following problem:
initially everything with connecting an external usb camera was ok. My usb camera app received events asking for permissions for using usb camera. But after 3 or 4 full charges the app stopped receiving permissions. I checked with couple other apps but again no permission. If my battery drops under 60% suddenly everything is ok again and the app detects the camera. It is stranger, that before full detect of the camera the app starts some kind of permission loop. I click allow and after 2 seconds the permission dialog shows again and so on... I checked the source code and appears my USBManager returns empty device list. For me it looks like some kind of battery optimizer or usb state optimizer doing it. I will be more than happy if someone can help me with this issue. Additionally I checked with all other stock rom version. It is all the same.
Here is some log from dmsg.
