    So lately my macbook "forgets" that has usb 2.0 and makes my ipod and my external hd work at snail 1.1 speeds:mad:. Happened in Snow Leopard and now in Lion.
    I did a pram / smc reset and I've already clean installed Snow Leopard and Lion and the problem still persists.
    Any ideas?

    Are you certain it's the USB that's the problem? Does it say in the System Profiler that it's connecting at the lower speeds? If so, it sounds like a bad logic board. Otherwise, a bad internal hard drive could cause the same "slow data transfer" symptoms.
