[Q] OTG Android 4.3 I9300 & I9305 topic

I have a Samsung Galaxy SIII, I dont remember the Android version, but i updated it one or two times, the last was 4.1 if i remember well.

I have an SIII LTE (4G) too, with Android 4.3 by default.

I bought an "usb OTG" cable, i try with the vendor the cable. with the SIII without Android 4.3, it's working so good, mouse, usb key, keyboard.
The SIII LTE with Android 4.3 refuse to work with OTG. I updated the SIII ( not the LTE) to Android 4.3 and now he refuse to use OTG too .


For both phones :

- Cable
Typicaly, the cable is detected, i have the message about the usb cable.

- Usb key
He detect the usb key and i have the message directly : "usb key removed correctly" (or something like this...he unmount the volume directly...)

- Mouse
I have the notification about the mouse is connected and is working .... but nothing is working exept the notification...

I dont know what to do, if someone have any idea, i'm fully ready to listen .... :/
