Dear all,
Does anybody use usb of BF54X? We design the PCB as ADI's reference design , and use default usb config in uClinux kernel.
When power on the unit, then plug in the USB device , nothing display in terminal. But when move off the USB device , it prompt the following message:
"musb_stage2_irq 796: unhandled DISCONNECT transition (a_idle)
"
The USB doesn't work, so pls help me to find out the problem?Thanks!

From the software point of view,the output message looks OK.My concern is about the HW circuit design.If possible would you post the schematic of usb part here?
Thanks
