Hey folks,
I recently got an USB Gyration Media Center Universal Remote, and it
works fine except for 5 buttons. In short, 4 of the keys are not
recognized by HID, and one of them repeats endlessly, even under
2.6.24-rc6. I gathered this info running evbug and
CONFIG_HID_DEBUG=yes.
This is what the remote looks like from /proc/bus/input/devices:

The specific problems:
1) The power button, which is actually a Sleep or Suspend button, when
pressed repeats endlessly. One must disconnect the receiver for it to
stop. I suspect this is because the key press event registers
correctly, but not the key release. From the logs, upon pressing the key:

2) Four of the buttons ("TV", "SETUP MENU", "LAST", and "INPUT") are
not recognized and do not register any events; only "TV" generates a
short debug message, but nothing else:

In my next post I'll attach the full log from the time the RF
receiver is connected to the time it is disconnected.
If I can fix the endlessly repeating key I'll be 90% happy, because
then I can use it to Suspend/Resume my HTPC. The missing keys would
be a bonus. The problem is I'm a kernel newbie, as as of yet do not
know where to begin. For starters, what is the most low-level USB
interface in kernel where I could start debugging this, just to see if
ANYTHING is getting through?
Thanks for your help,
Adolfo
