 While `uhubctl` compiles on Windows, USB power switching does not work on Windows because `libusb`
 is using `winusb.sys` driver, which according to Microsoft does not support
 [necessary USB control requests](https://social.msdn.microsoft.com/Forums/sqlserver/en-US/f680b63f-ca4f-4e52-baa9-9e64f8eee101).

 After powering down USB port, udev does not get any event, so it keeps the device files around.
 However, trying to access the device files will lead to an IO error.
