So I tested BT keyboards / mice / PDAs with very mixed results it appears the BTUSB service gets locked down when an UAC event occurs and depending on faith, trust & pixie dust I might get a working BT link back with the device afterwards.

No switching BT on & off via FN+F2 would help only a reboot would fix the issue. Bluetooth audio was - to put it blankly - knackered.

It was User Account Control requesting authorisation to continue, so I clicked OK and - nothing. wifi was off) and was listening to the latest Jean Michel Jarre via bluetooth headphones when suddenly the audio cut off. I was disconnected from my home network (i.e. So, the two radios weren't working together. Whatever Dell Support suggested didn't work, and in the end after numerous blue screens I had to do a factory restore. Straight "out of the box" BT and wifi didn't want to play ball - one would cause the other to drop their link forcing at least a FN+F2 or at worst a reboot. I've purchased an Inspiron 9400 ("The Slab") running Vista Premium with both a 54g and 355 Bluetooth card. (Basically - Widcomm 6.xxx stack flashes the bad software onto the device - I reinstalled that one twenty times, so it is the BT ROM software that is bad, not anything else.) Therefore there is no other choice but to use Dell's stack for Windows XP and stay with it, or upgrade that one to Anycom stack, but not Widcomm 6 offered by Dell for Vista. So therefore, when I reinstall Anycom after Widcomm 6, it doesn't work well. However, Dell's Widcomm 6 also flashes BT, and after that flash, the BT doesn't work as it is supposed to.

When I installed Anycom after that, Anycom didn't flash it, so the old ROM software worked great with new stack and drivers as well.

So I found the problem - When you install Widcomm 5 for XP on Vista, the BT 355's ROM is flashed, and it works good. I reinstalled Anycom and the error was still there. When I reinstalled it, the BT was showing the same error. So I tried what Dell originally offers for Vista, Widcomm 6 for Vista.

Finally I thought, maybe the new stack will provide a driver which would make Dell's stack work nicely. (I think version 6.) The Bluetooth worked great. I uninstalled the Widcomm 5 and installed the Anycom stack. So yesterday I went to anycom website and they had a newer BT stack for their 200-250 USB bluetooth dongles. However, I didn't understand why in the world would the old stack work and the new one not working.
