The same problem occurs with Ubuntu 16.04 LTS. Cold-boot, particularly, this seems to fail. Basically the problem is that usb_modeswitch_dispatcher is called with incorrect arguments. # systemctl --all | grep usb_modeswitch ● usb_modeswitch@1-9_1-9:1.0.service loaded failed failed USB_ModeSwitch_1-9_1-9:1.0 system-usb_modeswitch.slice loaded active active system-usb_modeswitch.slice # systemctl status -l usb_modeswitch@1-9_1-9:1.0.service ● usb_modeswitch@1-9_1-9:1.0.service - USB_ModeSwitch_1-9_1-9:1.0 Loaded: loaded (/lib/systemd/system/usb_modeswitch@.service; static; vendor preset: enabled) Active: failed (Result: exit-code) since Wed 2016-10-05 13:33:07 UTC; 1h 4min ago Process: 615 ExecStart=/usr/sbin/usb_modeswitch_dispatcher --switch-systemd %i (code=exited, status=1/FAILURE) Main PID: 615 (code=exited, status=1/FAILURE) Oct 05 13:33:04 giskard2 systemd[1]: Starting USB_ModeSwitch_1-9_1-9:1.0...

I'm using Ubuntu 14.10 and I've got USB 3G modem Huawei E173. If I use upstart, when I connect this modem, it is automatically switched to modem-mode and I can connect to the network. But if I switch to systemd, it doesn't, but I'm able to switch it manually using command: sudo usb_modeswitch -v 0x12d1 -p 0x1446 -V 0x12d1 -P 0x1436 -M 55534243123456780000000000000011062000000100000000000000000000 I'm using kernel 3.19.3 64-bit from Ubuntu Kernel PPA: 3.19.3-031903-generic #201503261036 SMP Thu Mar 26 14:37:55 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux All system packages are up-to-date.
