I'm experiencing a strange phenomenon. Every now and then (perhaps once per hour on average) my Win7 box emits the "Device connected" system sound (the one you get when you plug in a USB device) for no apparent reason. This can happen several times in a session, and there never is a "Device removed" sound in-between. I have no idea what's causing this. I'm not sure, but I think this only started after I had installed Dropbox.

Is there any way to find out which device Windows thinks has just been connected when it plays that sound?

I've seen this question, but the WDK requires me to install Visual Studio first, and I don't want to do that if possible. Isn't there something I could do with Sysinternals or some other tool?

+1 - I have experienced this too. Very annoying. But I have found no connection to Dropbox. I usually get it to stop by unplugging all my usb devices and reconnecting them. Sadly it doesn't always work. – Nifle Aug 24 '12 at 6:25
