I'm troubleshooting a very strange USB issue.

The computer I'm working on is a run of the mill Dell Inspiron desktop model. It has this weird problem of not working with all USB devices, especially storage devices. The peripherals that are currently installed are completely functional, but a simple WD Passport drive simply wasn't recognized.

The client recently tried using a basic PNY flash drive, but the drive wouldn't show up in Computer. It showed up in Device Manager, but with a driver issue. The problem is that these are, of course, plug and play devices with no drivers available. It should be built into Windows.

Any ideas?
