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