I just got myself this
Belkin mini Bluetooth adapter, it's not listed as a linux compatible device and isn't initially detected by the system. However, if you create a new configuration file in /etc/modprobe.d it works flawlessly.
i.e.
In
/etc/modprobe.d create a new file
belkin-btusb.conf and edit the file to contain only the following line
install usb:v0A5Cp21E8d*dc*dsc*dp*ic*isc*ip* /sbin/modprobe btusb; echo 0a5c 21e8 > /sys/bus/usb/drivers/btusb/new_id
Reboot the computer and the device will become active and hot pluggable
