[winusb_open] unsupported API call for 'open'

[Massimiliano-solutiontech]

I have problems with open_device_with_vid_pid on Windows. My goal is to write data using control transfer (the device is a CP2102N)

let handle = context
    .open_device_with_vid_pid(0x10c4, 0xea60)
    .expect("Failed to open device");

the program panics with this stack trace and debug log
