My Huawei E353 (Saunalahti branded), works out of the box in Ubuntu 12.04 32 bit (tested on my desktop), but on my laptop with 64 bit (can not install the 32 bit edition due to EFI) it is not recognized as a modem.
lsusb in the 32 bit edition gives 12d1:1506
lsusb in the 64 bit edition gives 12d1:14fe
I have tried various
usb_modeswitch commands but I can't get it to work.
