43   kind of addresses to store in urb->transfer_buffer and urb->transfer_dma.
44   You'd also set URB_NO_TRANSFER_DMA_MAP in urb->transfer_flags:
113   each time an urb completes and then re-map it on during resubmission.
115   These calls all work with initialized urbs:  urb->dev, urb->pipe,
116   urb->transfer_buffer, and urb->transfer_buffer_length must all be
117   valid when these calls are used (urb->setup_packet must be valid too
118   if urb is a control request):
120 	struct urb *usb_buffer_map (struct urb *urb);
122 	void usb_buffer_dmasync (struct urb *urb);
124 	void usb_buffer_unmap (struct urb *urb);
126   The calls manage urb->transfer_dma for you, and set URB_NO_TRANSFER_DMA_MAP
