Public bug reported:
I have a Huawei E220 USB modem. It worked in 2.6.28-11-generic (My First
Jaunty Kernel on fresh Installation) but not working in
2.6.28-15-generic (after update).
It is detected on both kernels, but even i can connect on both kernels, there
are several problems on 2.6.28-15:
1. Even though it can connect, i cannot access or connect to anything. The
modem keeps stalled, as if there is no connection at all.
2. After the connection has been established, I cannot disconnect it from
network manager. So, i have to unplug it instantly from the USB port if I want
to disconnect from the net.
Note 1 : It works prefectly from my Windows Vista Home Premium on the same
system.
Note 2 : I am curently using 2.6.28-11-generic when typing this report
