-/* 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: check if the cx25840-driver (from ivtv) can be used for the analogue
- * part
