Add preliminary support for the Medion Hybrid USB2.0 DVB-T/Analogue box.
Analogue part is not working yet (cx25842 --> ivtv?).

+/* 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
+ *
+ * FIXME: We're getting a lock and signal, but the isochronous transfer is empty
+ * for DVB-T.
