Hi!
Today I got my Filco Tenkeypad and plugged it on my Linux machine (running Crunchbang Linux, so it's Debian Wheezy with Openbox).
The Keypad doesn't work: Beeing not in NumLock-Mode, the arrow-keys are working fine. Beeing in NumLock and trying to type a number, the keypad freezes after the first press (but the key that is pressed, is interpreted correctly).
I googled for this issue and found this thread:
http://askubuntu.com/questions/304098/filco-majestouch-tenkeypad-not-working-in-13-04
... but there is no solution for me. Any ideas how to get it running?
Ubuntu 12.04 here. I have experienced the same problem a few days ago.
I wanted to use a number keypad to control a program that would accept only that, so I plugged the Filco alongside my Realforce 87U (TKL).
It froze all the time and I had to disconnect it, and then it froze again... I did not have the time to troubleshoot it, so I just dumped the Filco and activated the numpad option on the Realforce.
This Filco numpad also causes trouble on my Mac, some keys causing the numpad to autorepeat endlessly and then you have to disconnect it.
For a while, I have used this numpad on the Mac with key stoppers that prevented me from pressing the keys that caused problems, this way I could use it.
But I've got tired of it because I almost never really need the numpad.
Sorry, I know I'm not telling you how to solve your problem, but at least you know it's not a hardware failure with your device.
If you ever find a solution, I would be interested.
