USB Physical Port Mapping

Currently (Stable verstion is Proxmox 1.9) it's possible to map hardware usb port in a following way:

1. Find out physical port parameters (bus and port)

 qm monitor NNN
 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

2. Add the device to the particular VM (/etc/qemu-server/NNN.conf)

 args: -device usb-host,hostbus=3,hostport=1        # add Aladdin HASP device to VM (bus 3, port 1)

3. Power off/power on VM and check

 qm monitor NNN
 qm> info usb
