    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)?

    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.

    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.
