Hello,
We have custom board based on TI AM3892 processor. I would like to use USB device with my board. HID (mouse, keyboard) and usb-storages for the first.
During startup everything seems to be okay, but when we trying to plug-in mouse or flash-storage we receive following output:
hub 2-0:1.0: over-current change on port 1
hub 2-0:1.0: over-current change on port 1
hub 2-0:1.0: over-current change on port 1
same situations is when we try to plug-in device in other usb port
hub 1-0:1.0: over-current change on port 1
hub 1-0:1.0: over-current change on port 1
hub 1-0:1.0: over-current change on port 1
when we plug-in usb keyboard same message doesn't produced
People said that usually overcurrent happens when short circuit within usb on board exists. Could you comment this please?
Best regards,
Anton
