Public bug reported:
Ubuntu 11.10 32 bit upgraded from 11.04 on 12 Oct. 2011
What is expected to happen: The Logitech dinovo bluetooth keyboard/trackpad
should continue to work as before.
What happened instead: The keyboard now fails to connect and cannot be paired
with the bluetooth dialog.
The problem is in the udev rules. In 11.04 there was a special line in
/lib/udev/rules.d/70-hid2hci.rules for Logitech devices that started with
KERNEL=="hidraw*".
This is now missing in 11.10
I edited /lib/udev/rules.d/62-bluez-hid2hic.rules and changed the hiddev to
hidraw, saved the file and rebooted.
The keyboard and trackpad now work as expected.
The file as it exists now is less complex then the one in 11.04 as there
were several items listed in the Logitech section. I suspect that the
11.04 version allowed other logitech devices to work in hiddev mode.
Someone more knowledgeable then me needs to compare the 2 versions of
the file to ensure total compatibility.
The Logitech section from 11.04 looks like this:
# Logitech devices
KERNEL=="hiddev*", ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c70[35e]", \
RUN+="hid2hci --method=logitech-hid --devpath=%p"
KERNEL=="hidraw*", ATTRS{idVendor}=="046d",
ATTRS{idProduct}=="c70[4abc]|c71[34bc]", \
RUN+="hid2hci --method=logitech-hid --devpath=%p"
The Logitech section from 11.10 looks like this before modification:
# Logitech devices
KERNEL=="hiddev*", ATTRS{idVendor}=="046d",
ATTRS{idProduct}=="c70[345abce]|c71[34bc]", \
RUN+="hid2hci --method=logitech-hid --devpath=%p"
This is what I changed it to:
# Logitech devices
KERNEL=="hidraw*", ATTRS{idVendor}=="046d",
ATTRS{idProduct}=="c70[345abce]|c71[34bc]", \
RUN+="hid2hci --method=logitech-hid --devpath=%p"
