The first thing I would check is to see if the bluetooth dongle is a
supported USB device. If you look in /proc/bus/usb/devices for the
device, and check if it has a driver. Here are two examples of what
to look for.

Unsupported IrDA device:
T:  Bus=02 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 12 Spd=1.5 MxCh= 0
D:  Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs=  1
P:  Vendor=07d0 ProdID=4959 Rev= 1.00
S:  Manufacturer=Kingsun CO.
S:  Product=USB to IRDA
C:* #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=100mA
I:  If#= 0 Alt= 0 #EPs= 1 Cls=ff(vend.) Sub=00 Prot=00 Driver=(none)
E:  Ad=81(I) Atr=03(Int.) MxPS=   8 Ivl=1ms

Supported mouse:
T:  Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#=  2 Spd=1.5 MxCh= 0
D:  Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs=  1
P:  Vendor=045e ProdID=0040 Rev= 3.00
S:  Manufacturer=Microsoft
S:  Product=Microsoft 3-Button Mouse with IntelliEye(TM)
C:* #Ifs= 1 Cfg#= 1 Atr=a0 MxPwr=100mA
I:  If#= 0 Alt= 0 #EPs= 1 Cls=03(HID  ) Sub=01 Prot=02 Driver=usbhid
E:  Ad=81(I) Atr=03(Int.) MxPS=   4 Ivl=10ms

The S: lines will usualy give you an idea of what the device is. The
I line will show you the driver for the device. If there is no
driver shown, then you will have to see if you can find a driver for
it. This will probably not be easy is there isn't one in the current
