how to verify an usb device controller? I want to set uo an environment to verify the udc. Can anyone give me some advice and some reference materials? Thank
you very much!
 

what kind of usb device controller?
 

Most of company will buy USB analyzer to capture signals and transform to packet format according to USB protocal.
Maybe you can measure your controller using it.
 

It's better to use real application ckt to verify the functionality of the device controller. USB pen-drive design is a good starting verification vehicle. Besides, USB implementation forum also provide the characterization procedure for the validation of USB-related product. You can follow the procedure to verify your controller step by step.

Hope it helps
