There seems to be different kinds of CS-15 modems out there. For two of my devices lsusb -v gives 
"wMaxPacketSize     0x0040  1x 64 bytes" for a modem with bigger IMEI
and 
"wMaxPacketSize     0x0200  1x 512 bytes" for a modem with smaller IMEI.

The differences in behaviour with some current kernels can be found in
reported bug #496256 in comment #60.

  It worked fine with Ubuntu 11.10 so this is a regression.
