Comment # 5 on bug 905893 from lamon tagne

I have the same problem:
my USB 3G sticks workes very good in 13.1 and no more in 13.2. (Networkmanager
don recognize them)-

I found a way to make them work: I have to modeswitch them every time I plug
them wit usb_modeswitch then It works. But the next time, the stick has to
switch again.
