Hello Josh,

I do have the problem that plugging multiple modems short after each other (inserting with a script almost in parallel) does not get switched. It seems that usb_modeswitch_dispatcher cannot be run in parrallel or are there other ressources?

Logging is enabled but it rewrites the logfile since it does not contain the interface name as intended?

this is the syslog:

See, only 1-3.2 gets switched...

Oh, I just saw your post regarding a similar issue where you had a beta 1.2.1 available (http://www.draisberghof.de/usb_modeswit ... ta.tar.bz2) but it is not available anymore. Did this patch made it to some final version?
