Hi, I'm developing a USB audio firmware, it fails when URB_FUNCTION_SELECT_CONFIGURATION returns with result code USBD_STATUS_STALL_PID in usbuhci.sys. But the firmware has never stalled endpoint0. I want to replace the checked-build usbhub.sys/usbuhci.sys and see what's going on. Who can tell me where to get these drivers, and how to view the debug messages?
