Title:
Huawei E220 can't connect on Ubuntu 11.10
To manage notifications
If I may refer to my comment #85 - I had a look at the working and
nonworking log of modem-manager and pointed out the obvious
differences.
I strongly suspect that the newer version of MM is attempting to make use of
the diagnostic port, which can give status information (like signal strength)
Sleepy John: syslog log is pretty useless if ModemManager wasn't run
with --debug, :-/ And regarding the priority, I really don't give a s***
about it :-) I personally do this in my free time, so at least for me,
it doesn't matter if it was low or super-critical, I'll try to help if I
have time.
I'll follow up the issue in GB#662113

Great, so anyone requiring to use MM with the Huawei modem can fallback

Mark: step 4 not really needed; just killall modem-manager should do

Just thinking aloud to try and understand this problem better, we know

I think I have not been clear enough; the built-in switching function in the

we already know
The command from comment #13 will do nothing but send a standard device
reset control message to the modem. Any tool using libusb could do that,
so it's not a genuine property of usb_modeswitch. It was added just for
convenience.
And the workaround is quite logical: if something is screwing up
