Check usb_modeswitch/usb_modeswitch_dispatcher. If you move them out of the way, does that help? Older versions (like 2.4 and earlier) than the most recently released one would force-bind interfaces to some drivers which could interfere with kernel device matching. I just had this issue today for a Franklin U600 which should use cdc- acm on interfaces 0 & 1 and qcaux on 2-5. But the presence of /usr/sbin/usb_modeswitch_dispatcher prevented cdc-acm from binding. moving it out of the way fixed the issue, as would (I presume) updating my usb_modeswitch version.
