Hallo,
Es gibt wohl doch Probleme mit dem USB-HUB:
Alternative habe ich noch ein Aktiven D-Link Corp. DUB-H7 7-port USB 2.0 hub angeschlossen.
ls -l /dev/ttyUSB*
crw-rw-rw- 1 root dialout 188, 0 May 5 07:10 /dev/ttyUSB0
crw-rw-rw- 1 root dialout 188, 1 May 5 07:24 /dev/ttyUSB1
crw-rw-rw- 1 root dialout 188, 2 May 5 07:10 /dev/ttyUSB2
crw-rw-rw- 1 root dialout 188, 3 May 5 07:10 /dev/ttyUSB3
crw-rw-rw- 1 root dialout 188, 4 May 5 07:10 /dev/ttyUSB4
Hier die Fehler Meldung vom Kernel:

Auch ohne USB-HUB, erscheint die gleiche Meldung!
Ich hoffe es kann mir da einer weiter helfen.
