USB OTG/ Host Cable problems

Hello, I have a Galaxy S2, I just bought my USB OTG/Host cable. The funny thing is I can only connect mouse and I can use it. But when I use other USB devices like flash drives, I only get the light signal. I am unable to read or write to the flash drive. Any help?

Try going to Root/MNT/NTFS/SBA1 once your drive is mounted. Let me know if it works.

I cannot use my mouse its showing hi power usb device connected..

Maybe it needs external power supply? SGS2 is not really designed to power all devices from it's usb port.. but:
I've got working flash drives with fat32, keyboards and mice with Omega ICS + Syiah kernel.
Also, if you want to get NTFS flash drives working, download NTFS mounter from market.

My USB drives work well. I believe you need an app to mount the drives. Just search"otg mount" in GPlay. I'm using Chainfire's mounter personally.
I'm using the latest Siyah kernel with CM9(worked on Slim, Paranoid and Root Box too).
For some reason I just can't connect my mouse(wired) to my phone.

I'm using stock 4.0.4 LPM ROM, bought an USB OTG and every thing work perfectly, USB masstorange, mouse, keyboard, wireless mouse and keyboard... I think U should try another ROM, I recommend stock.

I bought another USB OTG/Host hub. Picture:

Now it works for flash drives, pen drives. Things like webcam, mouse, keyboard doesn't work any more. I am able to connect 4 flash drives at once as it has 4 ports. How? I heard from people that the 4.0.3 kernel doesn't support it. I doesn't want to root my device yet.
My Galaxy S2 info:
Baseband version: I9100DXLPA
Kernel: 3.0.15-I9100DXLPB-CL709089

I had the same problem with my Galaxy SII (stock ROM & kernel).
However, after the recent update from version 4.0.3 to 4.0.4 everything is working fine!
The only thing I have problems with now is my USB hub.
Interestingly enough, the keys of the USB keyboard I tried were correctly mapped to the german layout (QWERTZ). This was not the case in Android 2.3.
Even USB MIDI interfaces work now!

Xperia Pro USB OTG Pendrive not detected

Hi,
I flashed my Xperia Pro MK16i with the PACman 4.1.2 ROM 19.3. But it is still unable to detect pendrives on USB OTG. I tried installing USB OTG Helper but it wouldn't detect my pendrive. I found a video on one of the links on this forum which showed copying some modules to the root. I tried that too, but didn't help. Can anybody kindly explain me the steps to follow?
Thanks!

First, try to install it on linux system. If it doesn't work there, it doesn't work on android. But if you'll find driver for, you can try to compile it for your android linux kernel.

Install what on linux?

Hi,
i assume you got the usb-storage.ko installed at /system/lib/modules...
Install Android terminal or use adb to check your kernel output by typing dmesg at the prompt.
Some USB sticks ask for too much power during enumeration.
The kernel will block the access in that case.
On the Xperia 2011 devices we are limited to 300mA maximum at the OTG port using host mode.
Quoted from the datasheet of the charger IC:
VBUS is regulated to 5V at up to 300mA to power USB OTG peripherals
Click to expand...
Click to collapse
I realized this several times as well.
Many cheap sticks use the default setting in their firmware and ask for 500mA, which is too much for our phones.
Hope this helps!
Regards,
scholbert

You meant this? Well that's sad. It even detected the model number of my pendrive! And i'm guessing there's no workaround?
Thanks scholbert.
I'll double check on the power requirements on that pendrive and update. I want to see if it really asks for more than 300mA.

Yeah that's the message you get.
During enumeration, there's a request from host to device how much power is needed after fully initializing the hardware.
Sadly most USB stick manufacturers leave this entry in their USB memory controllers as default to 500mA,
because this is the current given in the USB spec.
In fact this is little stupid because most USB sticks do consume less than 200mA in real environment.
If you ask for a work around... then i would say: Try another stick!
If you like hacking hardware... then well yes you may tweak your stick by using factory tools and re-programm the entry which is checked during current request
You may start your search here: http://flashboot.ru/index.php?name=iflash&vord=0&pord=&pagenum=16
On a quick sight there's no real factory tool for the SM3255 available

Apart form measure the real current, you may check this with lusb -v on a Linux machine or digg deep in the Windows driver information with your stick attached.

You need to go to the usb connected in pull down and select usb 3.0 mode....by default the connection is in usb 2.0 mode
Not sure if it will work on mac, but that method works on pc

I would agree with you here, however, when I first got my Note 3 and connected to my MBP (same model as OP), it used to display the option, but ever since NB4 and beyond I haven't ever seen the option again.
The only thing I haven't tried, is launching Android File Transfer before plugging it in to see if that makes a difference, but I uninstalled that due to NE6 (and beyond)'s ability to show the internal and external sdcards as mount points.

Sent from my leanKernel 3.5 powered stock 4.4.2 (NF4) SM-N900T

after more research it apears more and more that the USB 3.0 is related to driver issues and not yet supported in OS X .... ill be setting up a bootcamp with windows 7 soon for testing but i'm almost certain its a issue with being supported under the os and not hardware...

MM, otg memory stick ?

Why doesn't the stock HTC file manager find the USB memory stick when connected with otg cable ?
It worked fine with Lollipop, could copy, move and delete files easily.
Cheers

It works for me ...
Do you have the latest update ?
Mine is 7.60.677939

Check if you don't have a faulty cable. Try with a different cable, or try your cable and see if it is detected on THAT phone.
Because, just like on the images of the previous posts, I've handled it the same way without any problem at all.

My stock and firmware is 707 too.
Did you update the HTC File Manager ? The one that come with the ROM won't work (I think, as I can't really remember).
Most of the 3rd party file manager/explorer unable to read OTG on Marshmallow.
Only the latest HTC File Manager is Marshmallow compatible.

Then .. I have no idea ... just tested my sandisk ultra dual usb ...
so no need for OTG cable .. it worked too.
and all my flash drives are FAT32

Mine is silicone power one 32g micro usb Otg flash (like yours) and the other 16g that needs Otg cable. In fact this is not only my problem some of the peoples reports that after mm updating. Thanks for your attention

I subscribe to this issue. After you upgrade to MM, the phone does not see OTG (two different cable, USB camera). Today replace the power board (thought it a problem), there is no result. Today bought a USB OTG Sandisk 16Gb also does not see. I put stock, Viper5, Viper6.

Mi 10T 5G usb otg & usb debugging not functioning on my phone itself.

Hi. I am Carlos from the philippines. I am a Xiaomi Mi 10T 5G user, and I have some issues with my unit regarding the usb debugging and my external USB suddenly it is not functioning on my phone anymore, and, even the tethering on my phone cannot also be selected for it to work. But, I can still charge my phone using my pc or charging brick, and even use the usb port for my headset. (with headset adaptor for usb type-c)
There is no problem with my pc or even my external usb, cause I have tried them on my wife's phone and the external usb and my pc can detect her phone. What could be the problem? Can anybody help me with this? Tia

I am also facing the same problem. Xiaomi Mi 10T Pro user here. OTG and USB options stopped working all of a sudden. I have created a thread here regarding the same. Some users in xiaomi europe forum have also reported the same issue. Looks like this is a hardware issue triggered by some specific setting. So far no solution.

Actually, I ordered a cheap priced charging port for Mi 10T from Shopee. It is not a original Xiaomi product but an OEM I suppose. It has not arrived yet, but, as soon as I receive it, I will go to a technician and have my stock charging port replaced. Maybe around less than month from now I will get back here and post the result. Cause, this is the last resort in finding solution to this issue...

4 days ago I had the same problem as you, I found a way to solve this error.
First you go to Settings, select All parameters, select Android version, if it is android 11, then you push the volume of android 11 up and down 3 times until it shows number 11, then plug the phone into the computer to see if it shows usb for file transfer.
