Comment 21 for bug 550288

Normally my Logitech diNovo Edge with its proprietary USB dongle is totally OS independent (does not need any drivers and did not even bring up Bluetooth applet).

It looks like the cause of this breakage is related to bug 444420 for 9.10, which changed hidraw* to hiddev*. Although, that never changed in my 9.10, which always worked fine with my diNovo Edge as hidraw*.

/lib/udev/rules.d/70-hid2hci.rules was changed in 10.04 LTS release, which even breaks installation unless you have another wired keyboard mouse to boot a live session and change hiddev* back to hidraw*. I don't know if there is more than one type of Logitech USB Bluetooth hid dongle, or if some people are unknowingly using some other 3rd party Bluetooth on their PC. But an even simpler solution is to comment out that entirely:

# Logitech devices
#KERNEL=="hiddev*", ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c70[345abce]|c71[34bc]", \
# RUN+="hid2hci --method=logitech-hid --devpath=%p"

Reinsert your Logitech dongle, and it should work (works for me from live session on 10.04 LTS CD).
