Conbee and Bluetooth on virtualbox

Hello,
I have tried to install hassio in virtualbox according to The Hook ups instructions, and it works well.

I connected my conbee II in my computer, added the usb device in virtualbox and started it. Under supervisor → System → hardware I’ll could now see my conbee stick as a serial by-id adress like this.

/dev/serial/by-id/usb-dresden_elektronik_ingenieurtechnik_GmbH_ConBee_II_XXXXXXXX-if00

I installed decons and everything worked fine. I’ll then restarted everything and the virtualbox started with the vmservice. Then the conbee stick wasn’t found anymore, under supervisor → System → hardware the serial by-id adress didn’t show anymore. so i tried with

/dev/ttyS0

instead which worked great even through vmservice. I’m gonna install both a RF-Link anda Z-stick to it so I would want to use the serial by-id adress instead of the /dev/ttyXX adresses. How can I do this?

Another thing I would want to do is to access my onboard bluetooth in my hassio so i can connect some miflora sensors and use bluetooth devicetracker. How do I do this?

My computer is a asus VM62 with windows 10.

Thank you!
