Hello,

Qemu upstream had achieved USB Passthrough Device Autoconnect Feature for the guest.

Such as a USB device is unplugged from the host then plugged back in to the same USB physical port.

 

the patch was:

However, Libvirt has not provided such an interface that identifies a USB device for pass through with physical port, rather than the device number.

 

Do you have any ideas or plans about this problem? Thanks in advance.

Best Regards,
