Welcome to the forums
You've "uninstalled and reinstalled" what, exactly? The chipset drivers? The OS itself?
From experience, I've found that: “Beauty is in the eye of the beer-holder”!!

i have reinstalled the os and the chipset
none of the usb devices work they will charge but thats it
Did you resolve this yet? I've just had this problem and eventually discovered that if I unplugged some of the devices already using USB ports, then new devices would work! E.g. I unplugged my printer and keyboard and then plugged in a digital camera - worked. Same thing for digital photo frame, etc. Must be a power supply issue. That being said....my keyboard has two USB ports in it and when I plugged stuff in there, it also worked! Who knows!
