The first eight bytes of this structure are the contents of the
SETUP packet to be sent to the device; see the USB 2.0 specification
for details. The bRequestType value is composed by combining a
USB_TYPE_\* value, a USB_DIR_\* value, and a USB_RECIP_\*
value (from *<linux/usb.h>*). If wLength is nonzero, it describes
``USB_TYPE_*`` value, a ``USB_DIR_*`` value, and a ``USB_RECIP_*``
value (from ``linux/usb.h``). If wLength is nonzero, it describes
the length of the data buffer, which is either written to the device
(USB_DIR_OUT) or read from the device (USB_DIR_IN).

These requests are packaged into a structure that resembles the URB used
by kernel device drivers. (No POSIX Async I/O support here, sorry.) It
identifies the endpoint type (USBDEVFS_URB_TYPE_\*), endpoint
identifies the endpoint type (``USBDEVFS_URB_TYPE_*``), endpoint
(number, masked with USB_DIR_IN as appropriate), buffer and length,
and a user "context" value serving to uniquely identify each request.
(It's usually a pointer to per-request data.) Flags can modify requests
