Failed to connect to USB on chromebook: Permission to access device was denied
问题 I'm writing app for chromebook that has to communicate with specific USB device. The device is present in the list of found devices, that comes from callback: var VENDOR_ID = 5824, PRODUCT_ID = 1159; document.getElementById("request-permission").addEventListener('click', function() { chrome.permissions.request({ permissions: [{ 'usbDevices': [{ 'vendorId': VENDOR_ID, "productId": PRODUCT_ID }] }] }, function(result) { if (result) { console.log('App was granted the "usbDevices" permission.');
