 /* DVB USB compliant linux driver for Conexant USB reference design.
  *
  * The Conexant reference design I saw on their website was only for analogue
  * capturing (using the cx25842). The box I took to write this driver (reverse
  * engineered) is the one labeled Medion MD95700. In addition to the cx25842
  * for analogue capturing it also has a cx22702 DVB-T demodulator on the main
  * board. Besides it has a atiremote (X10) and a USB2.0 hub onboard.
  *
  * Maybe it is a little bit premature to call this driver cxusb, but I assume
  * the USB protocol is identical or at least inherited from the reference
  * design, so it can be reused for the "analogue-only" device (if it will
  * appear at all).
  *
  * TODO: Use the cx25840-driver for the analogue part

	/* DVB USB compliant linux driver for Conexant USB reference design.
	*
	* The Conexant reference design I saw on their website was only for analogue
	* capturing (using the cx25842). The box I took to write this driver (reverse
	* engineered) is the one labeled Medion MD95700. In addition to the cx25842
	* for analogue capturing it also has a cx22702 DVB-T demodulator on the main
	* board. Besides it has a atiremote (X10) and a USB2.0 hub onboard.
	*
	* Maybe it is a little bit premature to call this driver cxusb, but I assume
	* the USB protocol is identical or at least inherited from the reference
	* design, so it can be reused for the "analogue-only" device (if it will
	* appear at all).
	*
	* TODO: Use the cx25840-driver for the analogue part
