As Virtualbox does a direct usb passthrough to the client I could instal=
l the bluetooth adapter in windows with the original broadcom bluetooth =
driver.
Once I opened the settings there and "saved" theses, the adapter finds b=
luetooth devices nicely under windows AND linux.
Sadly I have no idea what the broadcom driver did to "activate" the adap=
ter.
Does this make sence? For me not, but it works now.
When someone is interessted in any details, I will answer any question a=
s good as I can!
Perhaps someone can integrate the vendor id and product id in the kernel=
source btusb.c file.
The broadcom driver names the adapter 'Broadcom BCM20702 Bluetooth USB D=
evice'.
