    usb otg phy

    Hi

    The main diffrence between USB 1.1 and USB 2.0 standars is the speed....
    USB 1.1 works at 12 MBits/sec while USB 2.0 works at 480 MBits/sec.
    This major increase in speed was due to drastic changes in the standard. The whole hardware also had to be changed.

    Also USB 2.0 must has backward compatability....which means it should be able to comunicate successfuly with other USB 1.1 hardware.


    USB OTG is a new standard from USB-IF that enable host and device roles swapping within the connection. That was not allowed in USB 1.1 and USB 2.0.

    Hope this helps...If you have further questions don't hesitate...also refer to www.usb.org.

    regards,
    Shohdy

    difference between usb 1.1 and usb 2.0otg

    The main difference between USB 2.0 and USB 1.1 is the data speed.
    but USB OTG means OTG stands for on the go
    its mainly used for high speed as well as there is no need of pc interface
    u can directly connect ur camera with printer... like wise
