FWIW: I have the same problem. Running the usb_modeswitch_dispatcher results in the following:

After the switch to systemd, my 4G Huawei USB modem no longer functions as a modem unless I run usb_modeswitch to flip its state from USB mass storage. The command I issue and its output is below, which also show the Vendor and Product ID. Strangely, it does not do this every time. Yesterday when I updated using apt-get dist-upgrade upon reboot the modem worked as expected. But from a cold boot this morning it did not. $ sudo usb_modeswitch -v 0x12d1 -p 0x1f01 -J [sudo] password for damon: Look for default devices ... product ID matched Found devices in default mode (1) Access device 003 on bus 003 Current configuration number is 1 Use interface number 0 Use endpoints 0x01 (out) and 0x81 (in) USB description data (for identification) ------------------------- Manufacturer: HUAWEI Technology Product: HUAWEI Mobile Serial No.: FFFFFFFFFFFFFFFF ------------------------- Using standard Huawei switching message Looking for active driver ...
