Qubes OS supports the ability to attach a USB drive (or just one or more of its
partitions) to any qube easily, no matter which qube actually handles the USB
controller. (The USB controller may be assigned on the **Devices** tab of a
qube's settings page in Qubes VM Manager or by using the

You may also mount one partition at a time by using the same command with

**Warning:** when working with single partitions, it is possible to assign
the same partition to multiple qubes. For example, you could attach `sdb1`
to qube1 and then `sdb` to qube2. It is up to the user not to make this
mistake. The Xen block device framework currently does not provide an easy
way around this. Point 2 of [this comment on issue 1072][1072-comm2] gives
details about this.
