The hidraw interface

hidraw enables raw access to USB and Bluetooth Human Interface (hidraw) devices. This interface is restricted because it provides privileged access to hardware devices.

Auto-Connect: no

  • Should specify a single path attribute:
    • path (slot): path to hidraw device node e.g. /dev/hidraw0
  • Or three attributes:
    • usb-vendor (slot): integer representing the USB Vendor ID, must be in range 0 < vid <= 65535
    • usb-product (slot): integer representing the USB Product ID, must be in range 0 <= vid <= 65535
    • path (slot): path where a symlink will be created to the device e.g. /dev/hidraw-mydevice

Snaps that want to consume a hidraw device simply plugs: [ hidraw ] and the hidraw device to connect is specified during interface connection. Available hidraw devices for the system can be seen with snap connections. Once connected, the consuming snap can use the device via the path specified by the connected slot.

This is a snap interface. See Interface management and Supported interfaces for further details on how interfaces are used.
