Dear Jiri, I have got new news. I was able to play with my remote again.

First all the fields in the report is compiled and everything is ready, it is submitted to the kernel, so finally the user realized an effect. Can a report consist of many events ? > I still don't fully understand where do the events get lost in your case. > One possibility is that the machine is having a broken report descriptor, > resulting in the fields in received reports not being parsed correctly > (this wouldn't really be the first case of such a broken device). > > > This is fine, but a bit more of messages would be needed, namely: > > - report descriptor dump.

The dump should basically resemble > > drivers/usb/input/hid-core.c: report descriptor (size 59, read 59) = 05 > 01 09 06 a1 01 05 07 19 e0 29 e7 15 00 25 01 75 01 95 08 81 02 81 03 95 > 05 05 08 19 01 29 05 91 02 95 01 75 03 91 01 95 06 75 08 15 00 26 a4 00 > 05 07 19 00 2a a4 00 81 00 c0 Yes, I have exactly got such output. I found it in the log Its attached to this mail. ITs called "dump" > > - hid-input mapping. The respective dump should resemble > > INPUT[INPUT] > Field(0) > Usage(8) > Keyboard.00e0 > Keyboard.00e1 > Keyboard.00e2 > ... etc, then mapping dump, such as > Mapping: Keyboard.00e1 ---> Key.LeftShift > Mapping: Keyboard.00e2 ---> Key.LeftAlt > Mapping: Keyboard.00e3 ---> Key.LeftMeta > ... etc should follow This is also contained in "dump" but just that the mapping is IGNORED. the line "Input[Input" I was not even able to find in the kernel code. I hope It does not matter. I have got the feeling, that my remote control is not implemented at all in linux, and it has to be done. So I started writing down the bytes which are sent from the remote control. Its attached to the mail 'codes' If its really new, I also like to contribute some work for kernel coding. Maybe this is my chance. But my problem is that I dont have enough insight into hid at the moment. Can you tell me how to best proceed ? nice greets from zuerich -- "Feel free" - 5 GB Mailbox, 50 FreeSMS/Monat ... Jetzt GMX ProMail testen: www.gmx.net/de/go/mailfooter/promail-out
