Upgrading to BIOS v2.06 actually did change behaviour - it stopped the Ericsson F3507G card working on either Vista (where it previously worked) or my old Jaunty install (where it worked after resume from hibernate). That was quite... depressing, but in the end I wiped my Ubuntu partition, and did a fresh install from the final release of Jaunty. Lo and behold, the WWAN card started working on startup on Ubuntu! So I guess there must indeed have been something unpleasant in my /etc/modprobe.d/ or /etc/modules , which was wiped by the fresh install. However, the issue has now become reversed - in that the card no longer works in Ubuntu after resume from hibernate or suspend.
That's better than how it was before, even if it is rather mystifying. I don't know if it deserves a new bug report or not. The device certainly does show up as /dev/ttyACM0 when it's working - and isn't there when it's failing after resume. It doesn't work at all in Vista, which no longer detects it as a device - presumably this must be down to the BIOS update. Chris, if you have Windows on your X200 - does it still detect the device with BIOS 2.02 ? ** Attachment added: "LenovoX200.FullJauntyReinstall.WORKING-BEFORE-SUSPEND.20090428.tar.gz" http://launchpadlibrarian.net/26093058/LenovoX200.FullJauntyReinstall.WORKING-BEFORE-SUSPEND.20090428.tar.gz -- Ericsson F3507g (0bdb:1900) - does not display in NetworkManager, tho USB ACM devices are registered https://bugs.launchpad.net/bugs/363812 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
