Hi all i was recommended this website from another forum 
Right I have a problem, at the weekend i replaced my motherboard and cpu all is fine but for my USB ports its a strange problem because there is power running to them, however, i will install the drivers (or so it says) for the usb lead/input but will NOT appear as a removable disc for my ipod, digital camera or PSP. Even though they are clearly responding and there is power running through because it will charge my ipod.
I have my usb mouse and keyboard running fine from it (from its power of course).
I have also gone into the bios and made sure they are all enabled.
So ive tried everything, ive even been on the apple website and forum to try and find an answer, but the only help there is singling out the ipod, and it isnt only the ipod which is the problem.
Also yes i have been into the BIOS to make sure they are enabled.
Id appreciate any help
Thanks in advanced.
