After completed install of xubuntu precise i386:
inserting any USB modem, none are recognised (I tried E220, E169 and
E160E)
in dmesg all you see is the fake CDROM device, indicating the usb
modeswitch isnt happening
eventually I tried `udevadm trigger` with the E220 plugged in, and it
switched to serial and I could connect to the Internet with it when
modemmanager eventually found it. From this point on any of the modems
are recognized as USB serial when you plugin them in.
After reboot, back to square one until the first time you do a udevadm trigger.
