Gentoo USB serial passthrough KVM

I have a Conbee II Zigbee receiver. After a restart the USB passthrought stopped working (on the guest VM I always get errors like:

usb 2-2: new low-speed USB device number 25 using uhci_hcd
usb 2-2: Invalid ep0 maxpacket: 64 usb
usb2-port2: unable to enumerate USB device

So I decided, passthrough the USB serial. It’s a little tricky 🙂

    <serial type='dev'>
      <source path='/dev/ttyACM0'/>
      <target type='isa-serial' port='1'>
        <model name='isa-serial'/>
      </target>
    </serial>

The trick is the serial type because it is dev.
