Just FYI on the performance benchmarking using three different generic USB drivers.
HW: Cypress CYUSB3KIT-003 EZ-USB® FX3™ SuperSpeed Explorer Kit
Host SW to compare libusbk vs WinUSB:
Cypress data: from AN86947
From the data, libusbk and WinUSB are pretty close. But WinUSB is a
bit picky for the host when it comes to SuperSpeed isoc transfer compared
to libusbk, based on my testing. Cypress driver may still have an edge
in this aspect.
Info about libusbk project: open source USB driver and library. The
library supports WinUSB, libusbk kernel driver and libusb-win32
