Description:
Some months ago, was a long process required to activate the modem ZTE MF622 using usb_modeswitch, I describe it here -> http://wiki.archlinux-br.org/Claro_3G, after some time, this problem was solved(perhaps with kernel 2.6.28 or .29), just load the module option so that the modem worked, but now the old behavior back and module option seems not work properly.

I need to run the command eject /dev/sr1 I connect to the Internet.
Or follow the tutorial above.

P.S.: My Arch is up to date.

Steps to reproduce:
wvdial
pppd call provider
This task depends upon

Maybe you need to report to upstream devs usb_modeswitch, about the problem with the recent kernel. I think that is the best place than here.

PS: usb_modeswitch is in unsupported, not in Arch Linux repositories.

The problem is in OPTION module, usb_modeswitch is a workaround for problem.

OK. what is the module that is related here? what options related in the kernel?

option module works for me with AnyData ADU-500A so this must be specific to your hardware

the only relevant patch I can find is the one that adds support for your device: http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.30.y.git;a=commitdiff;h=9ea19b82f3126da4e47d6b94563a3c2cd586f6e2
so am not sure how it got broken after that. Maybe this caused it: http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.30.y.git;a=commitdiff;h=2400a2bfbd0e912193fe3b077f492d4980141813#patch15

Well, I am not sure if any of changes from git history has caused your issue, but anyway I suggest you to report this to bugzilla.kernel.org
Comment by Lucas Salies Brum (sistematico) - Monday, 20 July 2009, 02:02 GMT
I used the first link to revert the patch.
This is correct? Im not sure.
Tomorrow open a new BUG at bugzilla.kernel.org
Im waiting more instructions.

Thank you again.

Cool, reverting the patch that added support for your device actually fixes your device detection. :-D
Yeah, definitely report this to kernel bugzilla, things like this shouldn't happen.
