Re: [linux-dvb] DVB Driver for DiBcom's DiB7000M does not support the remote control for the kaiserbass TVStick

[David Wilson <dnwilson@chenopod.net>]

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 ?

regards
