/* 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 * * Copyright (C) 2005 Patrick Boettcher (patrick.boettcher@desy.de) * Copyright (C) 2005 Michael Krufky (mkrufky@m1k.net) * Copyright (C) 2006 Chris Pascoe (c.pascoe@itee.uq.edu.au) * * This program is free software; you can redistribute it and/or modify it * under the terms of the GNU General Public License as published by the Free * Software Foundation, version 2. * * see Documentation/dvb/README.dvb-usb for more information */ #include "cxusb.h" #include "cx22702.h" #include "lgdt330x.h" #include "mt352.h" #include "mt352_priv.h" /* debug */ int dvb_usb_cxusb_debug; module_param_named(debug,dvb_usb_cxusb_debug, int, 0644); MODULE_PARM_DESC(debug, "set debugging level (1=rc (or-able))."
