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
