USBHCDPipeStatus() in usbhostenum.c is useless:
uint32_t USBHCDPipeStatus(uint32_t ui32Pipe) { return(0); }
I need for this to work so that I can detect and recover from a write transfer failure that I'm seeing. The docs even refer to a value, USBHCD_PIPE_NO_CHANGE, which isn't defined anywhere in USBLIB.
