I have a Sony VAIO VPCSE1Z9E with the same internal Huawei 3G modem (12d1:14f1) and am also affected by this bug. The modem works with kernels <= 3.2.0-31 (qcserial driver) and doesn't work with any later 3.2.0 kernels (tried all up to -35).
The culprit is the "option" module claiming to support the device from 3.2.0-32 onwards, when it in fact doesn't (or at least not out-of-the- box currently). I can successfully work around this bug by blacklisting the option module. In order to do that, create a file /etc/modprobe.conf/blacklist- option.conf with the single line blacklist option as its content. With that blacklist entry, after a reboot qcserial can sucessfully operate the device again. I'm not sure how to resolve the bug though. Either we need to sort out how to operate the modem with option.ko, or the claim to support 12d1:14f1 should be dropped from it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1079359 Title: 3.2.0-32 drops huawei modem To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1079359/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
