PC doesn't recognize USB devices

[b33kewl]

my PC kept saying "USB not recongnized" anyway, I ignored it because my usb stuff worked fine. Until this morning, that's when none of my usb devices worked on my PC. I tried almost everything. Disabling my USB hosts in the control panel, restored my PC to when it was healthy. But nothing seems to work, I need help. I tried plugging my psp, usb thumb dive and even my iPhone, yet none of the will sync with my PC because my PC won't recognize an USB device for some reason. Honestly, all of this started one day when my brother needed help with his GPS he called Garmin n they sent him a USB cable; once I plugged it in and it was fix I left the cable in my pc and that's when all this started. Could that be an issue? Oh and I'm using Win xp. I tried everything I could think of safe mode,dsk chk and plugging everthing out. I need help.

And here's my usb info.

Try going into device manager and uninstalling all USB ports and hubs. Restart your computer and the USB ports will install themselves automatically when Windows boots.

^Okay....

it didn't work.. my computer still can't recognize my devices it will charge them, but it won't recognize any of them.

 

[Baez]

What is your computer model or if it's custom built your motherboard model?

 

[b33kewl]

It's a Gateway GM5072. Windows XP Media Center edition.

 

[Baez]

Get the Gateway GM5072 Chipset Drivers and install them. The motherboard chipset drivers contain the latest USB drivers as well.

^I'll try it now.

Nothing still isn't working. Could I of installed the wrong thing?

 

[Baez]

No I only gave you one file to download . Make sure you restart your computer after the install. Are you plugging the devices directly into the motherboard at the back or through the front or a USB hub?

 

[b33kewl]

^ I plugged it into the front of the pc. And I did restart.

 

[Baez]

Alright try a rear USB port that is directly on the motherboard and see if it works.
