But let's cover a basic thing about USB devices. You can't plug in most things and have it work. My printer would fail if I did that. I have to follow the instruction for each device.
Your post didn't reveal if you did that.
I have the same issue (USB) with my Dell Ispiron 1000 with XP (sp3). I couldn't figure it out so I ended up paying a lot of $$ for one of these online companies that did nothing more than remove and re-install the drivers. When the USB detects an additional it attempts to install the driver but errors out. "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)" I'm broke now... please email me at email@example.com.
