    what is differnce bet usb, usb2.0, usb3.0

    Hi
    The obvious diffrence is in speed usb2 480 Mb/sec. But about the protocols you can read usb1 and usb2 specs. Also there are many books on USB that you can find in ebook section.
    Good luck.

    the phy for 2.0 is very complex than 1.1, 1.1 phy is only two buffers. and the protocol is very different.
