Proposed workaround : http://bugs.treke.net/show_bug.cgi?id=792

The following rule in /etc/udev/rules.d/udev.rules should be corrected to use
something like :

SUBSYSTEM=="usb_device", \
   PROGRAM="/bin/sh -c 'export X=%k; export X=$${X#usbdev}; export
B=$${X%%%%.*}; export D=$${X#*.}; echo bus/usb/$$B/$$D'", SYMLINK+="%c"

Instead of the existing :
# usbfs-like devices
SUBSYSTEM=="usb_device", \
   PROGRAM="/bin/sh -c 'X=%k X=$${X#usbdev} B=$${X%%%%.*} D=$${X#*.}; echo
bus/usb/$$B/$$D'", SYMLINK+="%c"

Any other better solution welcome.

Best regards,
