/* 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
