Your app cannot do this automatically since this this procedure requires root access. This file should be owned by group "plugdev" and have group write permissions.
Run lsusb to find the bus and device numbers.You can check if device permissions are set correctly by following these steps: Then, just restart the udev daemon: service udev restart. If no devices are found, the array will be empty.Įxample: function onDeviceFound ( devices ) ="", MODE="0664", GROUP="plugdev" The detail of the identifier is opaque and subject to change. It will not change until the device is unplugged. The device property is a stable identifier for a connected device. The callback will be executed with one parameter, an array of Device objects with three properties: device, vendorId, productId. Your manifest must declare the usbDevices permission section listing all the vendorId and deviceId pairs your app wants to access.Ĭalled when the device enumeration is finished. The interfaceClass property can be combined with the vendorId property to get access only to USB devices from a specific vendor, as demonstrated by the following example: "permissions" : [Īn object specifying both a vendorId (long) and productId (long) used to find the correct type of device on the bus. implement a USB interface of a specific interface classįor example, the following usbDevices permission would grant an app access to all USB devices that implement a printer interface (interface class code 7), and to USB hub devices (device class code 9): "permissions" : [įor the list of acceptable interfaceClass values, see USB Class Codes.For kiosk apps, you can use the interfaceClass permission property to request permission to access USB devices that: Since Chrome 57, the requirement for declaring all the device types in the app manifest is relaxed for apps running as Chrome OS kiosk apps.
