ok, hier mal ein paar Angaben:
A) vor dem Ziehen und wieder Einstecken des USB Kabels
1. dmesg
...

B) Nach dem Ziehen und wieder Einstecken des USB Kabels
1. dmesg: da dürfte sich ja nix geändert haben, oder? Deshalb hier was syslog sagt:

Was mir hier auffällt: der Eintrag "Name=X10 WTI RF receiver" war vorher nicht da.

Tja, und schon geht die FB?!
