SOLVED: using BT COM Port on Windows host in Windows guest?

Maago · Post by **Maago** » 1. Jan 2009, 23:20

Hi all,

I'm using a Win XP guest running on a Vista host.
Now I'm trying to connect a Bluetooth serial connection in the XP guest but it doesn't work. Virtualbox don't start.

On Vista host the Bluetooth creates several COM ports (one of them is COM40). In VB configuration I tried to setup a serial port COM1 with a host path COM40 but this fails.

How can I route through the Bluetooth serial connection on host to guest?

Any ideas?

Thanks in advance
Maago

If your BT is a USB dongle or the sort, it might be better to use the USB feature of VB to pass the BT dongle to the Guest than to map the serial port.

unfortunally it is not a dongle, it is built in on my laptops motherboard ...

It's still possible they attached it to the USB bus. They do that with build-in webcams too.

this is maybe true .. USB is already enabled in guest but the program which I will use needs a COM port to work.

Ok, at the end now it works

The key was enabling the USB support for the BT USB interface. Then I installed drivers for BT in guest and it works.

Thanks!
