Say Y if you want support for Logitech Unifying receivers and devices.
Unifying receivers are capable of pairing up to 6 Logitech compliant
devices to the same receiver. Without this driver it will be handled by
generic USB_HID driver and all incomming events will be multiplexed
into a single mouse and a single keyboard device.
