Solved: USB drive flashes like crazy, can't remove it for 2 or 3 mins:verclsid.exe to

[Saussure]

My laptop runs on Windows Vista Home Premium with all the latest patches (exept for SP1, still need to install that one). When I plug in a USB drive, no matter which brand, the light of the USB stick starts flashing non-stop, and the mouse cursor, the standard arrow with that Vista-specific blue circle (equivalent of an hourglass, I guess), flickers along just as crazily. If I try to disconnect the USB drive (via safely remove hardware), I am told that another program may be using it, although not a single file on the USB drive is open. I can't disconnect the USB drive for a good two or three minutes until all the flickering and flashing has stopped. So I ran a HijackThis scan during the flickering and flashing. I have already saved an earlier HijackThis scan of my computer (no nasties, everything clean), and when I compared the two, I saw one process which had popped up during the USB "flamenco":

C:\Windows\system32\verclsid.exe

It disappeared after the flickering and flashing. What on earth is that? Isn't the entry above actually part of a Microsoft patch?

Never tried out safe mode. There are no nasties on the computer - HJT log was evaluated. It's a quirk which the computer got after a Windows Update, I think. I'm not quite sure. Could be something else.

Uhm...any answers? Suggestions as to how to fix this verclsid.exe/USB problem (if, as I suspect, verclsid.exe is responsible for the laptop's weird behaviour when plugging in a usb stick)?

Is Readyboost on for that drive?

Is Readyboost on for that drive?

Only on one of them, Sony Microvault. But I don't use ReadyBoost, and there is no U3 or portable apps on the drives. I would also like to add that my USB drives work perfectly on my other computer, a sony-vaio desktop running on windows xp home sp2. They also work fine on the university computers which run on vista business service pack 1.

Install service pack 1?

Install service pack 1?

Can't (as yet) - my SigmaTel audio driver version is listed as incompatible. Funnily enough, Windows Update has been trying to push SP1 out to me since last month - even though I've got an incompatible driver. That's a whole other story, and it has got its own thread.
I would also like to add that Windows Media Player crashed just a few minutes ago when I removed my USB drive. Now I'm wondering if WMP is to blame. Again, that is in another thread. I thought that this one was dead and no one was answering/knew an answer; and I thought that the title, which I cannot modify, sounds misleading, because it may not be that verclsid.exe process to blame in the end.

Okay, verclsid.exe doesn't seem to be the culprit. Installing Service Pack 1 for Vista seems to have solved the problem.
