Hi, after updating from version 0.4+git.20110124t203624.00b6cce-2 I cannot
use my USB modem anymore.

As it worked fine before, I tried to bisect the problem, which seems to be
in upstream commit dc89c0 "huawei: rework probing and detection". I had
some problems doing the bisection, because the first time it worked with
that commit, but it almost always hangs the modem and the only thing I can
do is unplug and kill modem-manager (and NetworkManager, or else it'll
respawn).

I'll attach two logfiles of "modem-manager --debug" one with the broken
commit and one with the working commit before it.

Regards

Does version 0.4.997-1 work for you?
I don't know if usb-modeswitch is needed or not, maybe try installing it.

It doesn't work, seems to behave the same way. I'll attach new logs
anyway.

usb-modeswitch isn't needed, the modem has always worked decently
without it and, as you can see in the logs, there are four serial
devices that belong to the modem.
