Comment 33 for bug 1315434

I could not easily find this workaround from a google search so documenting it here:

Typical "use with caution" notice, may cause a (small) rift in the space-time continuum, etc.

Edit /lib/udev/rules.d/95-upower-csr.rules (with sudo), comment out (with #) the last set of lines at the bottom so that it's left like this:

# Unifying HID++ devices
#SUBSYSTEM!="hid", GOTO="up_unifying_end"
#ATTRS{idVendor}=="046d", ENV{UPOWER_VENDOR}="Logitech, Inc."
#ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c52b", DRIVER=="logitech-djdevice", ENV{UPOWER_BATTERY_TYPE}="unifying"
#ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c532", DRIVER=="logitech-djdevice", ENV{UPOWER_BATTERY_TYPE}="unifying"
#ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c52f", ENV{UPOWER_BATTERY_TYPE}="lg-wireless"
LABEL="up_unifying_end"

^Everything commented out but that last LABEL.

On the next reboot, UPower will completely ignore these Unifying devices!
