VirtualBox USB passthrough

Quick steps to get USB passthrough working in VirtualBox.

Prepare the host

Install VirtualBox Guest Additions in the guest. If the in-app download fails, grab the ISO from download.virtualbox.org/virtualbox, mount the ISO in the VM, and run the installer from C:/.

Add your user to the vboxusers group on the host, then reboot so the permission change applies:

sudo usermod -aG vboxusers $USER

Verify USB visibility

After reboot, confirm that VirtualBox sees USB devices:

VBoxManage list usbhost

Optional: Extension Pack

Install the Extension Pack if you need extra USB controller support (run on the host with the matching .vbox-extpack downloaded):

sudo VBoxManage extpack install Oracle_VirtualBox_Extension_Pack-7.2.2.vbox-extpack
