   1 /* DVB USB compliant linux driver for Conexant USB reference design.
   2  *
   3  * The Conexant reference design I saw on their website was only for analogue
   4  * capturing (using the cx25842). The box I took to write this driver (reverse
   5  * engineered) is the one labeled Medion MD95700. In addition to the cx25842
   6  * for analogue capturing it also has a cx22702 DVB-T demodulator on the main
   7  * board. Besides it has a atiremote (X10) and a USB2.0 hub onboard.
   8  *
   9  * Maybe it is a little bit premature to call this driver cxusb, but I assume
  10  * the USB protocol is identical or at least inherited from the reference
  11  * design, so it can be reused for the "analogue-only" device (if it will
  12  * appear at all).
  13  *
  14  * TODO: Use the cx25840-driver for the analogue part
