cxusb.c

/* 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
