The main reason to use physical USB port mapping is to be able to connect several usb devices which have the same IDs to different virtual machines (device-1 to VM1, device-2 to VM2, etc).


To map hardware usb port use the following instructions:

The main reason to use physical USB port mapping is to be able to connect several usb devices which have the same IDs to different virtual machines (device-1 to VM1, device-2 to VM2, etc).

Map hardware USB port

Find out physical port parameters (bus and port)

Through Qemu/KVM tool (simpler)

qm monitor <VM_ID>
qm> info usbhost
 Bus 3, Addr 2, Port 1.2, Speed 1.5 Mb/s
   Vendor Specific: USB device 0529:0001, HASP 2.17
 Bus 5, Addr 3, Port 2, Speed 12 Mb/s
   Class 00: USB device 0624:0248, USB Composite Device-0
  • Example: Bus 3, Port 1.2 => 3-1.2

Or from the host

lsusb -t
/: Bus 05.Port 1: Dev 1, Class=root_hub, Driver=uhci_hcd/2p, 12M
/: Bus 04.Port 1: Dev 1, Class=root_hub, Driver=uhci_hcd/2p, 12M
/: Bus 03.Port 1: Dev 1, Class=root_hub, Driver=uhci_hcd/2p, 12M
    |__ Port 1: Dev 4, If 0, Class=vend., Driver=usbfs, 1.5M
    |__ Port 2: Dev 5, If 0, Class=vend., Driver=usbfs, 1.5M
/: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=uhci_hcd/2p, 12M
/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=ehci_hcd/2p, 480M
    |__ Port 1: Dev 2, If 0, Class=hub, Driver=hub/4p, 480M
        |__ Port 3: Dev 5, If 0, Class=comm., Driver=usbfs, 480M
        |__ Port 3: Dev 5, If 1, Class=data, Driver=usbfs, 480M
  • Example 1: Bus 3, Port 1 => 3-1
  • Example 2: Bus 1, Port 1, Port 3 => 1-1.3

Add the device to the VM

Proxmox 2.x and later

Edit the VM's configuration file /etc/pve/qemu-server/<VM_ID>.conf and add this line:

  • Example:
 usb0: host=3-1.2
  • Examples 1 & 2:
 usb0: host=3-1
 usb1: host=1-1.3

Proxmox 1.x

  • Example 1:
 args: -device usb-host,hostbus=3,hostport=1.2
  • Example 1:
 args: -device usb-host,hostbus=3,hostport=1
  • Example 2:
 args: -device usb-host,hostbus=1,hostport=1.3

Stop and restart the VM

Stop and start the VM (a reboot is not enought).

Check that the USB devices are seen by the VM: 

qm monitor <VM_ID>
qm> info usb
 Device 0.2, Port 1, Speed 12 Mb/s, Product QEMU USB Tablet
 Device 0.3, Port 2, Speed 12 Mb/s, Product QEMU USB Hub
 Device 1.1, Port 1, Speed 1.5 Mb/s, Product HASP 2.17
 Device 1.0, Port 2, Speed 480 Mb/s, Product USB Host Device
