Short story: Open up /lib/udev/rules.d/70-hid2hci.rules and find the following line:
KERNEL==”hiddraw*”, ATTRS{idVendor}==”046d”, ATTRS{idProduct}==”c70[345abce]|c71[34bc]“,
RUN+=”hid2hci –method=logitech-hid –devpath=%p”
Comment those lines out as follows:
# KERNEL==”hiddraw*”, ATTRS{idVendor}==”046d”, ATTRS{idProduct}==”c70[345abce]|c71[34bc]“,
# RUN+=”hid2hci –method=logitech-hid –devpath=%p”
Save, relog. Did the charm for me. If it does not work, read up on the link from above. There are other methods involving some changes to those lines.
Somewhat longer story: I installed Ubuntu 10.04 on my desktop PC this weekend. Everything went pretty smooth, that was up to the login screen. To my amazement my Logitech MX5500 keyboard refused to work. I managed to log in using the onscreen keyboard, but when i got inside Gnome I could not get it back up. After some pretty intensive copy-and-paste action from the FireFox homepage I was able to search for “onboard” and get that back up running. Google lead me to a Ubuntu Bug Report detailing this issue,
