Which key/mouse is it? I have a few I can test.

Logitech m315 nano-receiver (non-unifying)

Code:

usb 1-1.2: New USB device found, idVendor=046d, idProduct=c52f
usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=0
usb 1-1.2: Product: USB Receiver
usb 1-1.2: Manufacturer: Logitech

Sounds like the mouse may be generating too many interrupts.

@edwr: Try measuring them so we can compare.

Sure. How do I do this?
