DVB_USB_CXUSB - Conexant USB2.0 hybrid reference design support drivers/media/dvb/dvb-usb/cxusb.c: removed blobs
What is the purpose of the device?
/* 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 (firstname.lastname@example.org) * Copyright (C) 2006 Michael Krufky (email@example.com) * Copyright (C) 2006, 2007 Chris Pascoe (firstname.lastname@example.org) * * 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 */
Who needs it?
(which computer models use this device or which niche users usually buy such peripherals?)
How critical it is to get free support for it?
(Is it a very popular device that requires us to prioritize efforts?)
What is(are) the processor architecture(s) of this device?
Who is working on a free firmware implementation?
Links to online documentation
Where are the non-free firmware images made available?
What makes them non-free?
- Firmware source code is not available.
What else do we know about this device?
(any further info that might help the creation of free firmware for it)
It uses a Maxim MAX2165 tuner: http://www.maxim-ic.com/quick_view2.cfm/qv_pk/5306
