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.
Hi:
Thanks for your suggestion,this problem was solved.
Best Regards !
It could probably be that you don't have an HID driver installed on your PC.
I use the MFGTool,and I installed the driver.when i use the i.MX53QSB,and work well,so I think the driver is ok?
