Okay, you know how when you plug a device into your computer (well, a PC, I don’t know about Macs), you get a little icon in the lower right tray? Windows (I have Vista) makes a little dum-DUM noise, too. Then, when you unplug the device, it makes the reverse noise: DUM-dum.
Well, since yesterday, my computer has been showing that icon for about two seconds and making those two noises in succession every thirty seconds or so. It was so annoying that I disabled the sound files that are attached to plugging in and unplugging devices. When I tried to right-click the icon to see what imaginary device it would open, it disappeared.
Obviously this is not the end of the world. But the icon constantly appearing and reappearing is distracting, like something blinking out of the corner of my eye.
Is it a laptop? My laptop makes the same noise when I unplug the power cable, and says it is now safe to remove hardware. My thought is that if your power connection is going in and out that might be the problem.
If you have some devices attached wirelessly – keyboard and mouse, say – you might want to check their battery levels. It’s possible that there is a wireless signal fluctuating around its communication threshold.
This was the only post that’s applicable to the situation, so I gave it a shot. Turns out, every time the icon pops up, ALL of the devices in the Device Manager disappear. As soon as the icon disappears again, they reappear.
Really? I’m of the camp that believes that Macs fail less often specifically because the OS and hardware are built specially for each other.
Then again, garbage in, garbage out.

Kyla, failing in finding any conclusions by looking at the Device Manager, let’s try the Event logger. You can’t turn the darn service off (at least, not in Windows XP), so we’ll see if it actually recorded anything regarding your problem.
At best, you’ll be faced with a bunch of gibberish… (memory access fault in 0x000003B? EE 0A 6B???), but that’s where google comes in, hopefully with a solution.
When asking for this type of advice it is good form to supply all relevant information like computer type / brand / model / other relevant hardware details as well as OS details rather than having posters asking questions one by one and having to resort to waterboarding to extract information in a long and painful process.
Assuming the problem is indeed with USB, it is not necessary for anything to be plugged in outside the computer as many different internal devices can be connected. My laptop’s PCMCIA card and DVD-ROM drive appear as USB devices even though they are internal and are not even really USB. Other computers have internal USB card readers or other devices. If any of those malfunction they could cause such symptoms.
So the first question is whether there are any USB devices connected, internal or external.
If there are NO USB devices connected and the USB is having problems then we need to look closer at the drivers / controllers.
Well, sorry. I’m not a computer expert and I figured that the OS would be enough. Besides that, I’m using a four month old Dell Inspiron 1525.
I think I may have figured it out, though - I unplugged the power cord and it stopped. The power cord isn’t a USB device, is it? It doesn’t usually make any noise or show that icon when I plug or unplug the power cord, so I didn’t think that could be the cause.
After about twenty minutes of leaving the cord unplugged, I just plugged it back in and so far, no blinking icons.
I looked through the FAQ and the Forum but didn’t find anything right away but that looks like the best place to start.
ETA: I see there have been a few replies since I loaded this page at 2pm. Kyla, I think tzimmerman was trying to point you toward the power cable in post 3, but it sounds like you figured it out.
The fact that the sound is the “USB sound” is only a rough indication. The sound can be configured for other things as well. If you go to the control panel - Sounds , you can see what events have that particular sound and if there are several then configure different sounds so that each one has a different sound any you can know what event is causing it.
It seems you have already identified the cause though. It may be a power cord which was making bad contact.
