[Bug 868034] Re: Huawei E220 can't connect on Ubuntu 11.10

 

If udev starts usb_modeswitch, but usb_modeswitch can't find the device
when searching the busses, it means that something else is affecting the
device in the meantime. This should be visible when calling "dmesg"
after plugging in.

Either it's a driver thing (I'll check the source code of usb-storage in
a moment) or there is annother udev rule or hotplug mechanism kicking
in. I'll have a look in my 11.10 installation.

Regarding the other problems you mention, no. 1 is a known problem fixed
in version 1.2.0; about no. 2 I have no idea ...
