SABRE imx6q USB otg port input problem

Hi everyone,

 

I have the MCIMX6Q-SDB board.

I can't let the USB OTG input to work again, both with and without the HUB, with the "default" Android SD or my Linux build.

At the moment I'm using an USB adapter like this one

The keyboard won't even turn on its leds (Bloc Num, ...).

I've plugged in the keyboard befor turning the device on, after the boot process, during the boot process, but it never worked.

 

Is it possible that something was malfunctioning on the board? Any suggestion about further tests?

 

Thanks!

 

EDIT:

Forgot an important side note...

The USB port works correctly for uploading the SD card OS. So MfgTools on windows works correctly: the SABRE is seen as a HID device.

Looks more like an USB "input" problem.
