Same problem. USB Keyboard HAMA SL640 on Ubuntu 12.04 64bit.

So the OS recognized it but the keyboard doesn't react ... even the Caps Lock and Num Lock keys don't blink.
Regarding the legacy support (useful for GRUB), I have found no entry in the BIOS.
In GRUB it works sometimes.
On the same laptop I have Win7 in dual boot. And I have to say that it always works on it.
Surprisingly now I have booted my laptop: the usb keyboard hasn't worked in GRUB but it has worked since the ubuntu login! And now I'm typing with it.
It means that Ubuntu has the right drivers and they work. But how to "load" them always correctly?
