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
