QEMU usb-host driver which is the one for passthrough, supports two
options for selecting an USB devices in the host to provide it to the
VM:
- Bus and Device number the device is plugged
- Vendor and Product information of the USB devices
https://qemu-project.gitlab.io/qemu/system/devices/usb.html
This commit allows a user to configure podman machine with either of
options, with new --usb command line option for podman machine init.
Examples
podman machine init tosovm4 --usb vendor=13d3,product=5406
podman machine init tosovm3 --usb bus=1,devnum=4 --usb bus=1,devnum=3
This commit also allows a user to change the USBs configured with
--usb command line option for podman machine set.
Note that this commit does not handle host device permissions nor
verify that the USB devices exists.
