Windows 8

I have tried both a Wemos D1 R32 and a ESP32 UWB, but I can't open a device using WEBUSB

My code is

document.getElementById('getDevices').addEventListener('click', (event) => {
      navigator.usb.requestDevice({
        filters: []
      }).then(function (device) {
        console.log(device);
        return device.open(); // Begin
      })
      .catch(error => {
        console.error(error);
     });
});

The device appears and then when selected the error is

DOMException: Failed to execute 'open' on 'USBDevice': Access denied.

It is currently using the "Silicon Labs CP210x USB to UART Bridge" device driver.

I followed the instructions on this question but when I update the device driver software to point at this inf file I get the message

Select Device

The folder you specified doesn't contain a compatible software driver for your device. If the folder contains a driver, make sure it is designed to work with Windows for x64-based systems.

Rather than trying to use the WebUSB API, since your system already has the right UART driver installed, try using the Web Serial API.
