I know this is about USB drives, but I think the problem is actually with my computer, or windows.

It started with my iPod; it just stopped recognizing it one day. I tried reinstalling it, ect, but nothing worked. Now I just got a digital camera for Christmas which won't work with my computer. I know it's not the ports themselves, becauseI have a wireless keyboard/mouse, and my internet are plugged into them and they work fine.

Has anyone had this problem at all and know how to fix it?What computer or motherboard make/model/ Where are the USB ports on your system? There may not be ENOUGH power on the front ports for all of this, while the back ones have more. Strange to say, butr they are NOT all the same. Are these all USB 2.0 ports? Operating system and service pack? Other issues with the machine? How many USB device are you using in total? Details please.I hope I am giving the right information here.

MOBILE AMD Athlon(tm) XP-M, 2800+, 2.13 GHz, 192MB of RAM

Windows XP, home ed, v. 2002, SP2

Two ports on the front and 2 on the back. (Tried all of them). All 2.0 as far as I know. I only use 2 at a time, just for my mouse/keyboard and the internet.

I'm positive it's a refurbished computer, but I have had it for a year before it stopped recognizing my iPod. It is as if it doesn't want to connect with anything that it has to transfer files to and from.  I can't even pin it to something specific because I wasn't doing anything or had installed anything around the time that it stopped working.

With both my camera and my iPod, they wil show up in the tray in the right hand corner, but not as the...E? drive in My Computer.Look in Device Manager in Control Panel/System and see if any exclamation marks are present to identify any problems. I would try the iPod in the back USB and the mouse/keyboard in the front ones for this drill. What happens now? Then remove the iPod and see if JUST the camera is functional in the same USB slot. Then do the whole procedure in the other.

It is important to eliminate all of the variables except one at a time to isolate where the problem really is.

This is a laptop or desktop? What is the make and model number of the computer or motherboard?

There are no exclamation points, and plugging them in other places doesn't work/do anything different. It is a desktop. I can't find a model or make...but I just found a booklet for my motherboard in a box and it mentions limitations with the USB ports...so... I'll type out what it says and hopefully this is my problem.

"USB 2.0 Driver Limitations: 2-1. The USB 2.0 driver only supports Windows XP and 2000. 2-2. If you connect a USB 2.0 hub to the root hub, plugging USB devices into this hub, the system might not successfully execute certain USB devices' connection because it could recogd not recognize these devices. Currently we are working on a solution...ETC."

Would that there have been a problem from the start or could it just randomly start happening?
