Submit a previously set up URB to the USB stack

This routine submits a previously set up URB to the USB stack. The URB would have been set up from one of these functions:
For this release of the USB DDK, vendor requests are synchronous only. Therefore, the func parameter in usbd_io() must be NULL. |
The usbd_io() function is the one that actually makes the data transfer happen; the setup functions simply set up the URB for the data transfer.
