Hi,
When enabling the -device usb-host option support for adding automatically USB devices from the host to the guest, only one device gets detected.
Yes. -device usb-host creates a *single* virtual usb device instance. When a matching device on the host is found the virtual device is plugged in, otherwise it is plugged out. In plugged out state qemu looks now and then (every two seconds IIRC) whenever a matching device was plugged into the host.
Try -device usb-host twice if you need two virtual usb devices. cheers, Gerd
