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)

 qm monitor <VM_ID>
qm> info usbhost
 Bus 3, Addr 2, Port 1, 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

Add the device to the VM

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

 args: -device usb-host,hostbus=3,hostport=1

Or this line (as Proxmox 2.x supports usbN in vm.conf): 

 usb0: host=3-1

Reboot the VM

Check that the USB device is 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 0.4, Port 2.1, Speed 1.5 Mb/s, Product HASP 2.17
