The user can only experience the bug if she pairs 6 devices to a Unifying
receiver. The sixth paired device would not work.
The value changed is actually a bitmask that enables reporting from each
paired device. As the sixth bit was not set, the sixth device reports are
ignored by the receiver and never get to the driver.

There is a bug where a device with index 6 would write out of bounds in
the array of paired devices.
This patch fixes that problem.

With this driver, all the devices paired to a single Unifying
receiver are exposed to user processes in separated /input/dev
nodes.
Keyboards with different layouts can be treated differently,
Multiplayer games on single PC (like home theater PC) can
differentiate input coming from different kbds paired to the
same receiver.
Up to now, when Logitech Unifying receivers are connected to a
Linux based system, a single keyboard and a single mouse are
presented to the HID Layer, even if the Unifying receiver can
pair up to six compatible devices. The Unifying receiver by default
multiplexes all incoming events (from multiple keyboards/mice)
into these two.
