I've try to connect a USB Stick on a Samsumg S3... it work out the box: a pop up appears on Android und leds blinking on the device.
Then I try with another smartphone with a MTK6572 (Alcatel one touch idol mini), but it didn't work. I've use the same cable and the same USB Sitck
Maybe you will be luckier... but be sure to use a OTG cable, the 4th pin (sense) must be grounded to the 5th pin (GND) on the micro USB connector.

hello,
My phone :
- Samsung Galaxy S II
- Android 2.3.3
- operator : SFR FRANCE
- ROM : SFR original : PDA:KE4 / PHONE:KE1 / CSC:KE4 (SFR)
I have this USB OTG cable : link
but the phone can't detect any usb stick.
Any idea ?
Thanks
Is the OTG recognized when you plug it?
Have you tried another USB device like a mouse or keyboard?
I think it's a problem with the OTG.
Yes I've tried with a lot of usb stick, a DELL keyboard and a usb mouse
What do you mean by "Is the OTG recognized when you plug it" ?
Do you mean just the cable without any device plugged ?
No the phone doesn't detect anything
Thanks
Is it possible that usb host doesn't work with android 2.3.3 and only work with android 2.3.4 ?
Thanks
it is very easy:
if you plug in the cable alone, without a device attached to it, and there is no immediate notification, then you didn't get a proper usb otg cable, but probably only an adapter from micro usb to usb a female. i have seen the listing you posted, but apparently, whoever manufactured and/or sold it to you, forget one important thing:
there needs to be a resistor between pin 4 and 5 of (AFAIK) 200k because the resistor controls, what the sgs2 expects plugged in.
you will find all the information you need in this thread: http://forum.xda-developers.com/showthread.php?t=1070573
with a video on how it is supposed to work.
and btw. that thread was created in may and otg certainly does not require 2.3.4
I am a newbie can any one help me with the cable specifications ?
are micro usb all the same ? my mobile is charging well but i am unable to connect it to laptop even after PC companion and drivers and stuff i still cant get into usb mode in xperia x10. I dont have original xperia cable but nokia, samsung and HTc cables.
Secondly can partition effect this process (SD card parition for App2Sd)?
Try to find a micro usb that states 2.0 on it. I have the same issue with one cable that is used only for charging the phone. I'm not sure about cables from other phones. I would just buy a new one that states 2.0 on the package.
In my country , a seller tell that there is a cable for nook color suitable with nook tablet ! But i think they use different chip , so that it cant suitable? Is this right?
Is there any OTG cable suitable with NT ? I want to connect it to usb 3g modem !
So I tried using OTG devices with the Blackview Ultra with both the stock rom and CyanogenMod 12.1 installed but it just doesn't work. I have tried multiple USB OTG cables and none have worked, I know it is not the cable because it works fine with my friends phone. I have also run USB Host Diagnostics on the phone and it says that the OS supports OTG but simply no device is detected.
The bizarre thing is that the Ultra itself claims OTG support. It even comes with an OTG cable included in the box!
So if anyone could give me some insight on this it would be greatly appreciated. I really want to see some USB devices working with my phone. Thank you!
Bump
Anyone?
Hi I try to connect my usb mouse to my Xperia but I noticed that my cellphone not recognize my mouse so I tried another devices like card reader or pendrives and the cellphone do nothing. So theres someting that I have to do to make OTG working? I'm on the lastest official mm (note I never try OTG before, in lenovo K5 my OTG cable works)

Q1:
Have you tried connecting your device to the computer via a USB cable? Can the computer recognize it?
If no, maybe there is problem with your USB port.
If yes, proceed to the next question.
Q2:
Have you tried changing the connectivity state for the USB port in Settings?
If not, try it out now.
If yes, report back and we'll discuss further more.
Use Es File Explorer... That's what I've been using
Sorry for late reply, I got it working, I replaced the usb cable, I think that the quality of the cable was too bad
