Dear Sirs,

I would like to control power per port in windows as I can do in Linux (tested).
I have compiled uhubctl for windows and tried with usblib 1.0.21 and compiled also 1.0.22rc2 and activating debug I see there is with both an error on libusb_open the usb hub device:

[ 0.187506] [000002d8] libusb: debug [libusb_open] open 1.0
[ 0.187506] [000002d8] libusb: debug [winusb_open] unsupported API call for 'open' (unrecognized device driver)
[ 0.187506] [000002d8] libusb: debug [libusb_open] open 1.0 returns -12

Default driver of the USB HUB (D-Link DUB-H4 H/W Ver.: D1) is USBHUB3.SYS, I have tried also to replace it using zadig-2.3 by libusbK, libusb-win32, and WinUSB having same error.

Any chance to have this working?
Is it not possible to read/write directly the hardware?

Best regards,
Manel
