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
Attributes:

  • 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

To to use a hidraw device, the snap developer must add plugs: [ hidraw ] to a snap’s snapcraft.yaml. The snap user can then access a specific hidraw device with an interface connection.

Use snap interface hidraw to see which hidraw devices are available on the system.

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.
