Find usb controller for particular device

[proxwolfe]

Hi,

I would like to pass through an entire usb controller to a VM.

Is there a way to find the usb controller for a particular usb device? (I want to find out which usb ports would be passed through together with the usb controller. So I was thinking I would plug in a device in port after port and write down to which controller it connects...)

Thanks

Hi Matrix,

I had seen this page but discarded it as not relevant for my venture - I do know how to pass through USB devices.

But I gave it another look and found the mention of the command "usb-devices" which gives a lot of info and, apparently does not only show all usb devices connected to a usb bus but also the host controller behind it - exactly the Information I was looking for. So thank you for tip!
