hi,I custom a board ,the processer is  i.MX537, the design is very similar with i.MX 535QSB.

when i test usb ,the windows display “Unknow device”,I check  the power supply and all  voltage  are OK.

Anybody has  experience about this?

Best Regards!

Please try using an external self-powered USB hub between i.MX53 and PC.

Do You mean USB issue with internal UART / USB boot(ROM)loader of the i.MX53 or problems with OS (Linux) under i.MX53 ?

The driver is ok.now my problem is that the windows can not identify  theUSB device,display “unknown device”.

I checked the USB part of our design,no mistake was found.

It could probably be that you don't have an HID driver installed on your PC.
