Christopher M. Penalver: I have managed to run the BIOS upgrade. It does seem to have made a significant difference, but it still falls short of ideal behaviour.
The original behaviour with the A05 BIOS was that, without the 'mousefix' installed in crontab or /etc/rc.local, the Logitech Unifying Receiver was detected, but inoperative. This was not changed by re- plugging the device any number of times. After the BIOS upgrade to A07, the device can be enabled after a small number of re-plug cycles. On 5 test boot-ups, the receiver started working after a range of 0-3 replugs, with a mode of 1 (on one boot no replug was needed, on another 3 were required). After re-installing the 'mousefix' the reboot behaviour seemed to be somewhat improved over 5 trials, in that all 5 times the mouse and keyboard worked after just 1 re-plug cycle of the receiver. I would need to do a lot more power cycle trials to see if this was significant. FYI I eventually got the Dell BIOS upgrade to run using a Windows 7 System Repair Disk. With the .exe installed on a separate USB, all I needed to do was get to the command prompt from the repair disk boot and navigate to the correct drive letter. This does not seem to be documented anywhere, in particular with regard to Ubuntu, so I will put this info up on one of the Ubuntu forums. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1072082 Title: 046d:c52b Problems using Logitech Unifying Receiver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1072082/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
