Description of problem:

You're gonna love this, I'm sure :)

I have a Huawei 3G stick, which "stopped working" recently. Actually what had happened was that I'd inserted a MicroSD card into it, to use as a flash stick, and with that the 3G stuff doesn't work any more.

When you insert it, it lights up as usual, and NetworkManager makes an effort. It doesn't ever connect, though.

Once I take out the MicroSD card, it works again - although sometimes won't come up automatically, but I suspect that's due to the confusion the first time around.

I'll attach some /var/log/messages excerpts for attempts with and without the flash RAM.

Something to try, all as root:

1) service NetworkManager stop
2) NM_SERIAL_DEBUG=1 /usr/sbin/NetworkManager --no-daemon
3) wait a bit
4) insert the stick
5) (as your user) try to connect

Attach the stuff that NM dumps out and lets see if we can figure out why the card is unhappy.  When you've got what you need, hit Ctl+C to kill NM, then you can 'service NetworkManager start' and you'll be back to normal.  THanks!

This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.

Go to your phone company get them to upgrade your firmware, it fixes this problem.

Yeah, I've heard from a couple of users that early-version Huawei devices have issues like this, so a firmware upgrade is likely the best way to go.  If your 3G provider doesn't have a firmware update available, sometimes you can find them from Huawei's site as well.
