	  This function sends a simple control message to a specified endpoint

	  If successful, it returns the number of bytes transferred, otherwise a negative error number.

	 Don't use this function from within an interrupt context, like a

	  a message from within interrupt context, use usb_submit_urb()
	  If a thread in your driver uses this call, make sure your disconnect()
	  method can wait for it to complete.  Since you don't have a handle on
	  the URB used, you can't cancel the request.
