Questions:
1) Does the Bluetooth device use the Microsoft bluetooth stack? or a
third-party bluetooth stack?
2) Have you installed the bluetooth software which came with the
device?
3) Is the bluetooth software included with the device recent (i.e.,
this year and Vista-compatible?) If not, go to the manufacturer's
website and download a newer driver, if there is one. If there isn't
a newer driver, you might as well forget about using that device under
Vista.

A few thoughts:
1) Try to avoid the Microsoft Bluetooth stack if possible. Microsoft
has a buggy Bluetooth stack. And there is no work-around. Just make
sure you buy Bluetooth devices which don't use the Microsoft stack, if
at all possible.
2) I've found that Logitech devices have the best control of Bluetooth
under Windows (any version), especially XP and Vista. The Widcomm
stack which was included with Logitech devices previous to Vista works
fantastically well on XP, and not at all under Vista.
3) Vista's networking is buggy, and you might experience your
bluetooth devices dropping during network operations more often than
not. I experience such interruptions in network operations even when
I navigate away from the current Browser page while iTunes is open and
playing a file, or when I open a new file under iTunes while my
browser is open.
4) Vista's native Bluetooth configurator loses contact with various
dongles, etc., quite often. Don't use it, if possible.
5) If your device includes configuration software, use it, rather than
the native Vista Bluetooth configurator.
6) Make sure you've got the latest driver from the manufacturer of
your device. If it is not a native Vista driver, get rid of that
device, and replace it with one which does have recent (this year)
drivers and software.
7) If your device does NOT use Vista's native Bluetooth stack, DISABLE
the Microsoft stack in Device Manager, or it will be guaranteed to
interfere with the stack your device does use.
8) Never use two different Bluetooth stacks. They will interfere with
each other.
