This driver originally used the 'attach' method in order to get
the firmware for the device from the comedi_config utility. It
now uses request_firmware_nowait() in the usb_driver probe to
get this firmware.
Since this driver has an 'attach_usb' method in the comedi_driver,
the 'attach' method can be removed because it is now optional.
