The USB dongles themselves are stupid and don't have operational
firmware in them.
It's a cost-saving measure. By using uploadable firmware, the
manufacturer (Dlink, Linksys, whoever)
doesn't have to make a Windows version and a Mac version and a Linux
version.
They just make one type of device and then ship the appropriate
firmware blob on the drivers CD.
So the real reason you need the BlueZ firmware is that the driver has
to upload the right firmware(in this case, for Linux) into the
bluetooth module itself, otherwise it won't work.
HTH,
