Huawei E1552/E1800 (12d1:1446) doesn't modeswitch

[Colin Ian King]

My 3G USB dongle (Huawei E1552/E1800) doesn't modeswitch automatically.

I can get it to work using following magic in /etc/usb_modeswitch.conf

DefaultVendor= 0x12d1
DefaultProduct=0x1446

TargetVendor= 0x12d1
TargetProductList="1001,1406,140b,140c,141b,14ac"

CheckSuccess=20

and then forcing it using: sudo usb_modeswitch -c /etc/usb_modeswitch.conf

Also, just to add that I'm seeing the following segfault when I plug in the device (without using my hack'd usb_modeswitch.conf, just using the default Precise configs):

[92337.840423] usb_modeswitch_[1693]: segfault at 8 ip 00007f12d1690541 sp 00007fffc2576158 error 4 in libc-2.13.so[7f12d160a000+197000]
