Medion MD95700 (DVB-T)

MD97500 with remote

A DVB-T USB device from Medion.

It is supported by LinuxTV (although, not completely; see below).

Overview

The following drivers are needed for these devices:

 - cx22702.ko
 - dvb-usb.ko
 - dvb-usb-cxusb.ko

The analogue part (handled by a Conexant CX25842) is not supported yet. The cx25840 driver from ivtv can be used to implement support.

	Comments & quirks
Medion MD 95700 4in1	USB2.0	Conexant CX22702		Inner circuits (tuner)
	The box also has a X10 remote control. This is radio, not IR, and is supported by the ati remote driver. It also has a USB2.0 hub (Tetrahub) with one additional USB port. Both of them are working without mains power.

There is a new firmware, version 1.0.2.14, for the MD 95700 from Medion. You can download it directly: [1] (in German). Please read the Readme before you flash the box.

This update fixes some video problems, but it is incompatible with the old dvb-usb drivers (i.e. kernels from 2005). If you use your box under Windows, don't forget to ensure that the Windows drivers are up to date too.

Distro-specific note: Using the Medion MD95700 with Suse 10.1

please review this text ... thanks!!

On a Suse 10.1 default smp kernel, the driver module dvb-usb-cxusb.ko is missing. The USB box can not be used without building this module. The sources of this driver are in the files drivers/media/dvb/dvb-usb/cxusb.*.

The driver for the Medion MD 95700 is referenced in newer kernel configuration as "Conexant USB2.0 hybrid reference design support". Yast uses the term "Conexant DVB-T reference design".

To build this driver:

• Install kernel-source, gcc, ncurses and optional kernal-syms
• cd /usr/src/linux
• Optional copy the current kernel configuration: cp /proc/config.gz .config
• Enable the build of the missing module:
  • su
  • make menuconfig
  • Device Drivers -> Multimedia Devices -> Digital Video Broadcasting Devices -> Conexant USB2.0 hybrid reference design support -> build as Module
• Build either the the whole kernel inluding modules or this single module. The build process is described in /usr/src/linux/README.SUSE
• Install the module(s)
• Load the module using "modprobe dvb-usb-cxusb". On reboot, the module should be automaticallly loaded if the box is connected.
• The devices /dev/dvb/adapter0/* should be created on module load
• Configure the box using Yast -> Hardware -> Tv Card -> Add -> Other -> Conexant DVB-T reference design
• Install and configure your favorite DVB Tv application

Note: The current Suse kernel source "2.6.16.21-0.13" has the new dvd-usb drivers included and therefore can handle boxes flashed to the firmware 1.0.2.14.

LIRC configuration

1. remove the kernel driver ati_remote when you want to use lirc. you can do it by blacklisting it or recompiling your kernel (check your distro's infos on that)
2. set up lirc and the kernel drivers (you'll need the lirc_atiusb module) according to what your distro says.
3. use the following for /etc/lirc/lircd.conf (or however it's named in your distro):

# brand: Medion MD1 NBC
# Made in China X10
# Medion Remote Control
# * FCC ID: B4S20018268

1. start lirc and configure your app to interact. there are pretty many howtos for the major apps on the net.
