This solution solved my problem with Logitech Wireless MX 5500 on Ubuntu 15.10 Wily Werewolf! 
I have keyboard/mouse combo from Logitech named Logitech Wireless MX (Revolution) 5500; this combo has 1 bluetooth dongle to receive input from both mouse and keyboard.

I was using it without problem on Ubuntu 14.04 LTS. 
I just switched to Ubuntu 15.10 and keyboard/mouse do not work at all!!! After some search, I found this webpage and tried that solution: 
Change: KERNEL=="hiddev*" 
To: KERNEL=="hidraw*"
After reboot, MX 5500 Wireless keyb/mouse combo now works on Wily Werewolf.

On 15.10 Wily Werewolf though, the path to the modified file is: 
/lib/udev/rules.d/97-hid2hci.rules 

I modified line 14: 
From: KERNEL=="hiddev*", ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c70[345abce]|c71[3bc]", \ 
To: KERNEL=="hidraw*", ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c70[345abce]|c71[3bc]", \ 

Thank you for sharing the solution :)

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"
