| /* 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 |
