 |

Hi Folks,
recently I purchased a MS-Tech MC-1200 case for my new HTPC. The case comes with a remote control. The remote seems to be some sort of keyboard, since it does not communicate over lirc.
This is the relevant output of lsusb:

It works out of the box, but only 80%. I still miss the ESC key and so on. I do want to adjust it to my, respectively to mythtv's needs.
Any ideas how I can achieve that. I was thinking of formulating some hal policy... But I don't know where to start. How can I translate the keys pressed on the remote to the action I want?
(There is also a keyboard attached, which works fine and I don't want to mess it up...)
Google didn't help me much. Although I did a rather intense search.
I figured out I might use lirc with inputdevice, but if there is no need for lirc, I don't want to introduce it.
The other disturbing thing is, that the irda-receiver also responds to my hifi-remote. Which leads to going backward in a movie instead of turning down the volume...
So basically the question is. How can I make this remote, which seems to be some sort of keyboard/mouse to do what i want?
Many thanks in advance!
Alex

I think I got it...
Since it is a keyboard, I simply have to figure out which button on the remote corresponds to which standard keyboard action. I made good progress with the xev-tool.
On the other hand, no need for rocket science, since you can use MythTV's keyboard configuration. The problem though is, that it also changes the standard behaviour of the regular keyboard.
One death you have to die...
cheers!
Alex
