I've got a basic USB device here - a USB CDROM. I'm installing it on a brand new Dell workstation. One would think the process would require no more than plugging the thing in (that's what "plug and play" is for, right?). Well, no such luck. After I connect the thing to the computer, it tries to start installing the driver. But it always fails and ends up with this error:

An error occurred during the installation of this device

The installation failed because a function driver was not specified for this device instance

I've searched MS's site and didn't find anything helpful. I've Googled it, and am not optimistic because I have found several mentions of this error, and in each of them the person went as far as formatting and reinstalling Windows, and they still got the error!

Any ideas?
