Xhci may be the culprit.

Everything about latency. This section is mainly user/consumer discussion. (Peer-reviewed scientific discussion should go in Laboratory section). Tips, mouse lag, display lag, game engine lag, network lag, whole input lag chain, VSYNC OFF vs VSYNC ON, and more! Input Lag Articles on Blur Busters.

none, except i don't ned to replug mouse after boot to get stable polling rate, there is some uefi - os pre-boot handshake bug where mouse polling rate won't go higher than 1000 or even go lower unless you unplug and plug your mouse back.
Well, thats disheartening. More than likely back to the drawing board then.

Get a PCI/PCIe adapter and PCI USB card. There's far more PCI USB 2.0 cards available, new and used. Windows drivers might be a problem though.
