I have setup Proxmox now. I Have installed and setetp a CT (Ubuntu server template) .

Now to get a program what i am using to work, I need to have access to a BD Dongle.

lsusb is showing the BT device:

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 0451:16a8 Texas Instruments, Inc.
Bus 001 Device 002: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)
Bus 001 Device 004: ID 0403:6001 Future Technology Devices International, Ltd FT232 Serial (UART) IC
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

How can I access the BD dongle ( Bus 001 Device 002: ID 0a12:0001 ) to a CT?

hcitool scan shows:

Device is not available: Address family not supported by protocol

When i setup a VM and assigned the USB device ID the the VM, it is working fine.. But I want to use a CT due the resources.

This was extensively discussed in our german forum (link), here's the gist of it:

Bluetooth devices register themselves as a network interface, so passing through the USB /dev node is useless. Sadly, the BT network adapter is not namespaceable, meaning it can't be assigned to a container the way regular network interfaces can.

So in essence, it's highly likely that you're use-case will not work the way you envision it. I suggest just using a VM, with KVM and ballooning configured a VM is pretty lightweight too these days.
