:title: Incus USB devices
The `usb` device type is supported for both containers and VMs.
It supports hotplugging for both containers and VMs.

USB devices make the specified USB device appear in the instance. For performance issues, avoid using devices that require high throughput or low latency.

For containers, only libusb devices (at /dev/bus/usb) are passed to the instance. This method works for devices that have user-space drivers. For devices that require dedicated kernel drivers, use a unix-char device or a unix-hotplug device instead.

For virtual machines, the entire USB device is passed through, so any USB device is supported. When a device is passed to the instance, it vanishes from the host.

Device options

usb devices have the following device options:

Key Type Default Description
gid int 0 Only for containers: GID of the device owner in the instance
mode int 0660 Only for containers: Mode of the device in the instance
productid string - The product ID of the USB device
required bool false Whether this device is required to start the instance (the default is false, and all devices can be hotplugged)
uid int 0 Only for containers: UID of the device owner in the instance
vendorid string - The vendor ID of the USB device
