Host USB ports assigned to guest

[0badc0de]

Hi all.
I need to assign some USB ports to one of the guests.
This is to allow unknown USB device to be "seen" by the guest when inserted in those specific ports.
I am reading this guide but I am not sure to fully understand it.
I would expect to only make some actions on the host.
I cannot match the output for "info usbhost" before and after the power cycle of the guest with the data I see.
I need to be sure on what I do as the shutdown+restart should be done only once in my case.
Any hint?

can you a bit more specific what you want to do?
if you want to pass through a usb port, you simply need to configure that

the example on the guid you linked is rather clear on how:

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

Well, the example actually lead me to the solution. Just did a few extra tests.
I used the details from "lsusb -t" .
Thanks.
