can anyone please help me . ive been trying to figure out how to fix my usb. when ever i plug in something like a camera,ipod,cellphone it wont read it. and usually when i plug in my ipod it charges right away but not this time. i might have uninstalled something in my computer. also my printer it doesnt work too. maybe i have a usb port problem? i really dont know help please. and i check my device manager the universal serial bus (usb) contoller has a exclamation mark next to it. what do i do? i want to put new pictures in my computer but it wont read it. help please.

If Santo's method doesnt work,you will need to download and install the correct controllers.

my friend bought a product that helped him a lot.. its an online guide about iPod repair.. maybe you guys might wanna check it out
