Windows 7: Dreaded USB device not recognized

I'm also not sure this is power related. Any device I plug in on top of the 4th has power to it. For instance, my phone will charge as normal.

what is your legacy device setting on in BIOS
Do you have a USB hub you can try out and see if it is possible to add more devices that way?
Do all USB ports work if you plug your 4 devices in in other ports?
If you add a 5th device with its own power supply does it work?

Pooch, I'll check my legacy device settings in the BIOS after this post.
I do have a USB hub I'll try out.
All my USB ports work. I've already tried plugging the 4 devices into various ports and they all work fine.
One of my 4 devices is a 2TB external drive with it's own power supply. It works fine but doesn't work if I plug it in as the 5th device.

Ok, I guess I don't have a USB hub to try. I thought I did.
I don't have the option in the BIOS menu for USB legacy options.
Any more ideas I could try before I wipe it clean and start over?

Ok I think a New install could potentially save time Before you do that can you confirm these BIOS settings, assuming I have the right manual. See attachment.
Do you use the easy energy saver? if yes be aware and I am guessing here that it might limit power to the USB ports.
Check in Device Manager that Power Management is turned off for all USB Devices

All my settings mirror the ones you've posted. I'm really baffled. I can't help but wonder if this may be a faulty MB. I'll probably be forced to do a fresh windows install. Whats the best way to do that?

I believe you,

Last try at a fix. I can't think how you could have plugged the front/extra USB ports in wrongly and they still work, but best check them again, maybe unplug and replug them, then try the new install if you still have no joy

Have a look here; Clean Install Windows 7

You should be able to get the board checked by a reputable dealer, then you will know for certain if it is a faulty MB

Let us know how you get on

I did double check that I had the USB ports plugged into the MB correctly. It definitely wouldn't hurt to check them again.
As far as the mother board goes, I'm an American living in Italy. Italians aren't exactly technologically savvy. I'll have an extremely hard time finding a dealing to check the MB. MB's aren't really all that expensive so I could just buy another. Before I do that, I'll try a clean install. When I first got the system up and running I installed windows and ran it without the chip set drivers for a good bit of time. Maybe 2 weeks went by before I realized that I needed to do that. So, once I did that, the USB drivers worked better but not great. I did a repair install of windows, and the USB functions got better yet. So here I am. They work but they're not working perfectly. I'll let you know how the clean install goes after I get everything backed up.
