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). * * * Copyright (C) 2005 Patrick Boettcher ([email protected]) * Copyright (C) 2006 Michael Krufky ([email protected]) * Copyright (C) 2006, 2007 Chris Pascoe ([email protected]) * Copyright (C) 2011, 2017 Maciej S.
