Option GE0301 3G modem doesn't work

ok, the culprit is that bInterfaceClass is "8 Mass Storage" (on lsusb -v output). So I need to reset that somehow, and the jaunty kernel doesn't have the infrastructure to do that automatically, found on 2.6.29:

http://www.kernel.org/pub/linux/kernel/people/gregkh/usb/2.6.28/usb-unusual-dev-for-option-n.v.-zerocd-modems.patch

but there are tools to get past that.

I will cherry pick http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=281b064f237205053ef1874ffc77b9211265af4c add your patch and build a test kernel.

Can you pls confirm that this kernel works ?

It will be nice if I can get this verified by Tue so that it can make it into Jaunty easily.

Thanks! I'll try it out ASAP, which means during this weekend.

Ok, so it does disable the storage interface, but my patch is not enough because it doesn't use option_ms_init which would basically rezero the device. It's needed for the hso driver to be able to pick up the device, otherwise it'll just fail saying "Not our interface". (bDeviceClass needs to be 'ff', and it's '00' without option_ms_init).

I'll attach another patch which is meant to work with the upstream commit I posted.

I've built the kernel locally with the upstream patch and mine, and now the device works fine! Network manager sees the device, but fails to authenticate. It might be a bug in NM, will investigate.

Patch submitted for jaunty kernel, moving to incomplete.
