Such problems are mostly related to the hardware. Is this the internal root hub or an external? Check power and proper routing to the device I would suggest. Also turn on debugging, then you see a more detailed error message.

Hi,

I'm getting a same error on a custom board based on imx253.

The error is a timeout error.

Also get "devpath 1 ep0in 3strikes" when debugging is turned on.


Same port works fine in device mode.

Any pointers to debugging would be nice.


Thanks.

Issue I'm getting was traced to hardware and it's been fixed.
