"Cannot run two device installations" problem persistent

I cannot add any new hardware on Vista Home Premium. Whenever I connect a new
hardware (USB memory stick, DV camera, anything basically) Vista won't run
the Add Hardware wizard and if I manually select "Add Hardware" from Control
Panel I get a pop-up window saying "Cannot run two device installations" and
it says another device installation is underway. However, I have checked all
possibilities (hidden and non-hidden) from Device Central in Normal and Safe
Mode and removed all the devices that were not working properly (a Bluetooth
dongle that was apparently not vista compatible) and the problem still
exists. Googling for this I found a few postings that were for XP, and
relating to deleting a registry key, but those reg keys are not in Vista.
Thank you in advance.

Can someone kindly respond to this query because I'm also experiencing this
same issue.

I still have the same problem, but only sometimes now. Installing every
single hotfix I could find and rebooting before and after plugging in any
hardware seems to do the trick. But that's only for some devices, a lot of
the devices I try to plug in won't work. And since I need to prototype
hardware on my computer I find this extremely frustrating. My only choice is
to use my old computer with XP. This is sad, because I bought a new computer
to work more efficiently, but most of my days are now spent with trying to
fix all the problems Vista has.

Finally figured out that the problem is my firewall. So to femi just turn
off your firewall for a while and the problem should go away. At least it did
for me.
