I have Bianca (2.6.17-11) on a laptop Fujitsu-Siemens PA1510 that I mostly use with an external USB keyboard with no problems.
I tried to install Cassandra but I get that if the USB keyboard is connected, the internal kb doesn't work.
This is a problem to me because I lose the caps & number lock leds and the use of some special function keys (volume, contrast, etc.)
Does anybody know what is changed ? (in the kernel, I think, thus I get the same with other new distros).
