Windows installs the hub driver for hub-class devices so a WinUSB functions won't work.

HI ,

I think, I can update the driver for this External hub and make WinUSB loaded for that.
For many of the USB device there already exists inbox but still we can load our own custom driver using update driver.

Thanks

If you assign the WinUSB driver, the device will no longer receive hub-class requests, etc.
