virt-xml: Attach host USB hub to a running VM (See: tldr lsusb).

virt-xml

$ virt-xml ${domain} --update --add-device --hostdev ${bus}.${device}

try on your machine

This command is used in a virtualization environment, specifically with the "virt-xml" tool, to update and add a host device to a specified domain.

Let's break it down:

"${domain}" is a placeholder for the name of the domain or virtual machine you want to update/add a host device to. You need to replace "${domain}" with the actual name of your domain.
"--update" is an option that tells "virt-xml" to update the specified domain.
"--add-device" is another option instructing "virt-xml" to add a new device to the domain.
"--hostdev" is used to specify the type of device to add, in this case, a host device. The following part "${bus}.${device}" is further substituted with the actual bus and device numbers of the host device you want to add.

In summary, the command is used to update a domain and add a host device to it using the "virt-xml" tool. You need to specify the domain name, use the "--update" and "--add-device" options, and provide the bus and device numbers of the host device.
