Re: USB HID: Missing keys on Gyration Media Center Universal Remote Control

[Philippe Troin <phil@fifi.org>]

Jiri & all,

What's the status on this bug?

I used this patch for 2.6.24:

It was working fine.

With 2.6.25.6, I've been trying to use the following patch.  It's a
slight modification of a patch posted previously by Jiri.

However this patch does not seem to work at all:

 * the Power button keeps repeating the power key once pressed

 * the home (windows MCE green button) and the four keys below it
   (shortcuts to movies, music, photos, tv) do not work.

Is there anything I can help with to get a working patch?

Thanks,
Phil.
