theKing2...As long as you like all the other changes in 11.10, you can
try the upgrade.  Just change the hiddev to hidraw and your
keyboard/trackpad should continue to work.  In fact, now that I think of
it, if it was working before the upgrade, then perhaps you should make
the change as soon as the upgrade process is finished, but before you
reboot.  That way your system should come back up with working keyboard.
Otherwise, you will have to plug in a wired USB keyboard/mouse to make
the change.

If you wait for this to be addressed by the Dev's, you might be waiting
till April 2012 and then it may still not be "fixed".

Something else to watch for is that after I got it working, there was a
bluetooth update that set the hidraw back to hiddev.  I noticed it
before I rebooted, so I just changed the file back before rebooting and
didn't have any further trouble.  The lesson here is to look at the
updates so you know what to expect before rebooting.  This happened a
few weeks ago, so if you are just starting the process now, you already
have the "new" bluetooth update and don't have to worry.

If you are just doing the upgrade now, you only have to do the fix once.
If you are doing a clean install, then do all the updates after the
install before fixing the keyboard issue or you will just have to do it
again after the bluetooth update is applied.

Title:
  Logitech Dinovo Bluetooth keyboard fails after upgrade to 11.10

Status in “udev” package in Ubuntu:
  Confirmed

Bug description:
  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"
