We go over some quick fixes to make sure your system recognizes USB devices.

I have a problem with my USB ports. Say I plug in my digital
camera to upload some pictures to the tower or plug in my iPod to put music on
it, my system won't recognize that they are plugged into the USB port unless I
restart the entire system. This can get very annoying having to restart the
computer every time I want to upload pictures, use my webcam, put music on my
iPod etc. I have asked many of my friends if they have the same problem with
their USB ports, but they don't. My system won't recognize anything that is
connected into USB unless the system is restarted.

USB is great when it works, but as you're experiencing, it can still be a
pain when it doesn't.
USB's really only been around for a few years, and while most of the kinks
have been worked out, not all of them have. Especially if you're on an older
machine or operating system version.

Since I don't have the specific configuration of your system, I can only
make some general suggestions. USB functionality can be affected by many, many
things.
"USB functionality can be affected by many, many
things."
- Make certain that your version of Windows is up to date by visiting
Windows Update. There have been updates to the USB
support in almost every version of Windows, especially the 9x and Me
versions.
- Make certain that your system BIOS is up to date. BIOS support is an
important part of USB support, and just like the operating system, there have
been updates. Exactly where and how to get an updated BIOS will vary depending
on the manufacturer of your computer - check with them.
- Make certain that your USB hardware drivers are up to date. The drivers are
the hardware-specific interface between Windows and the USB ports. Getting
updates to these drivers will depend on the manufacturer of your computer, or
the manufacturer of your USB port add-in if the USB ports are on an expansion
card, so you'll need to check with them.
- If you're running Windows XP, run the system file checker to ensure that
Windows itself is not damaged: What is the System
File Checker, and how do I run it?.
- An up-to-date spyware and virus scan wouldn't hurt either.
- If any software came with the devices you're having trouble with, make sure
that's up to date, and installed properly.
The problem is that any or all of the above items could possibly impact your
USB problems.

My problem is that my laptop does not recognize one of my USBs only. It detects all the others fine. There is nothing special about this one except that it has a built-in camera (to help me catch critters eating my plants at night!) The first time I plugged it in, the laptop did recognize it. But after that one time, it never did again.
