Re: Zowie Celeritas modifier keys not working in usb mode

[Alberto Mattea <alberto@mattea.info>]

I investigated the problem and found out two things:
1) The keyboard works correctly in grub2
2) More important: the keyboard works correctly in Linux IF I use the simple 
HIDBP driver (usbkbd) instead of the regular one.

So now I'm using usbkbd as a workaround, but this way I cannot use advanced 
hid devices like joysticks (becouse they are incompatible with HIDBP drivers).

Is there any other information I can provide which could be useful?
Thanks
