(**Note:** In the present context, the term "USB stick" denotes any [USB mass storage device](https://en.wikipedia.org/wiki/USB_mass_storage_device_class). In addition to smaller flash memory sticks, this includes things like USB external hard drives.)
Qubes supports the ability to mount a USB stick to any AppVM easily, no matter which VM actually handles the USB controller. (The USB controller may be assigned on the **Devices** tab of an AppVM's settings page in Qubes VM Manager or by using the [qvm-pci command](/doc/AssigningDevices/).)
As of Qubes R2 Beta 3, USB stick mounting has been integrated into the Qubes VM Manger GUI. Simply insert your USB stick, right-click the desired AppVM in the Qubes VM Manager list, click **Attach/detach block devices**, and select your desired action and device.
A command-line tool, `qvm-block`, is also available. This tool can be used to assign a USB stick to an AppVM as follows:
1. The USB stick is now attached to the AppVM. If using a default AppVM, you may open Nautilus file manager in the AppVM, and your stick should be visible in the **Devices** panel on the left.
