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