[Kai Krebber]

Hi!

Ich habe 2 USB (2.0) - Sticks, die  - wenn eingesteckt in mein Sarge-Notebook 
(krebber:/home/kai# uname -a
Linux krebber 2.6.10-vs1.9.4 #1 Thu Mar 24 23:23:14 CET 2005 i686 GNU/Linux)
nur nach mehrmahligem Versuch (reinstecken, 'rausziehen - die Assoziation ist schon fast peinlich) sauber eingebunden werden:
