udev-rule for old huawei sticks

Writing this throug my old e156G (the e160 is a rebranded e156 AFAIK).
Try copying the attached 10-Huawei-Datacard.rules to /etc/udev/rules.d
Reboot _without_ the e160 stick; first reboot may be slow, udev has to rebuild
its configuration.
Login normally, connect the e160, wait 30s or so; dmesg should show the
following:

option 2-3:1.0: GSM modem (1-port) converter detected
usb 2-3: GSM modem (1-port) converter now attached to ttyUSB0
option 2-3:1.1: GSM modem (1-port) converter detected
usb 2-3: GSM modem (1-port) converter now attached to ttyUSB1

without further disconnections or error messages; connect the usual way (I use
NetworkManager). It works for me in openSUSE 13.2 with both 3.16.6 and 3.17.3
kernels, but may be configuration-dependent. You loose the internal microSD of
the e160, but other usb sticks work normally.
