Dear All:

I am using Blackfin BF527 version 0.2. The USB part of schematics is same as one present in EZKit LITE. i am using USB in device mode. USB_ID pin is left floating.

USB gets detected some time(I am using HostApp to verify the device and also performing loop-back test successfully) and some time doesn't. (Device doesn't get detected, Also I get message in PC telling that 'USB device malfunctioned' in baloon message)


Please suggest possible checks i can perform so that USB will get detected every time i power on.
