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!

 

The following message shows the info of usb driver :

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
