Hi,
I'm using an AM3894 board and i'm trying to use an AOC touchscreen.
The video is ok, but when i try to connect the usb cable to get the mouse input, I have these errors:

... until i disconnect it.
The problem persists if i change usb port.
I think that in my touchscreen there's an hub with 4 ports and maybe the problem is it.
How can i solve this problem? My system has ezsdk 5_03_00_09 installed.
Thank you in advance.
