Public bug reported:
Binary package hint: network-manager
I'm running Karmic x64 on an Acer TravelMate 6292.
When I plug in my Huawei E172 USB HSPA modem, it sometimes shows up in
Network Manager and other times not. I can sometimes fix it by
unplugging and plugging in again (in another USB port). When it is not
detected, I see the following in the syslog:
