DVB Driver for DiBcom's DiB7000M does not support the remote control for the kaiserbass TVStick

I have purchased the kaiserbass TVStick product ID 'KBA01007-KB DVD-T USB TUNER WITH 2 GB MEMORY'. The Linux-DVB Driver for DiBcom's DiB7000M driver works very well for video, but the software driver does not support the slim 28 key remote control provided by kaiserbass.

The evidence is the error codes in the system log. For example pressing any key causes a system log error, the volume up key results in the system error message:

2010-11-14 13:07:26    Capulet    kernel    [10464.828505] dib0700: Unknown remote controller key: 0000 2b d4

I tried adding a new set of key codes to the DiB7000M-devices.c file i.e.

{ 0x2bd4, KEY_VOLUMEUP },

but this did not work, perhaps I have used the wrong conversion or format for the key values. Here are the key values from the system error messages

KEY_MUTE            0AF5
KEY_SOURCE          38C7
KEY_SCREEN          0FF0

This is my first attempt at working on a linux driver and I need some assistance.

I have purchased the kaiserbass TVStick product ID 'KBA01007-KB DVD-T USB TUNER WITH 2 GB MEMORY'. The Linux-DVB Driver for DiBcom's DiB7000M driver works very well for video, but the software driver does not support the slim 28 key remote control provided by kaiserbass.

The driver has support coded for several ir remote devices but not for the unbranded slim 28 key one supplied with my tuner.

The driver reports unrecognised remote key sequences it receives, for example, the volume up key results in the system error message:

2010-11-14 13:07:26    Capulet    kernel    [10464.828505] dib0700:

Unknown remote controller key: 0000 2b d4

I tried adding a new set of key codes to the DiB7000M-devices.c file i.e.

{ 0x2bd4, KEY_VOLUMEUP },

and compiled and tested it but this did not work, the driver still reports the keys as unrecognised. Perhaps I have used the wrong conversion or format for the key values.

I have looked at the MS Windows driver configuration that came with the tuner - modrc.infl, it defines the volume up key as:

HKR,,"ReportMappingTable",0x00000001,\
\;0x01,<SystemMSB>,<SystemLSB>,<Data>, <Flags>, ...
....
0x01,0x00,0x00,0x2C, 0x0B, 0x04,0x00,0x42, \ ; AC volume up
......

I can not see the relationship between controller reported in the system log - key: 0000 2b d4 and MS defined - 0x01,0x00,0x00,0x2C, 0x0B, 0x04,0x00,0x42

So there seems to de some some code conversion going on or incorrect reporting of the key input.

Can anyone assist me with this ?
