    Hi, I have a MX27 Lite Kit and I cannot get USB OTG to work in peripheral mode. We are not required to work in host mode.
    So far when I connect the Lite Kit to my Linux FC5 laptop, the PC does not detect it.

    Can someone take a look at my config below to see if I am missing something?

    Also the Lite Kit uses the SMSC USB3311 transceriver chip. Does anyone have the programming manual? I only have the Data Brief. I am not sure how different it is from the Philips 1504 chip, which the MX27ADS board uses. If anyone knows much about the differences between these 2 chips in terms of programming, can you advise?

    Sorry I am posting a MX27 question on the MX31 forum. The MX27 forum does not have much activities.

    Thanks a million!
