    I've just gone back and had a look at the project I used.

    I made one change in the file usb318xcfg.h

    It was originally:

    #define OTG_1301_DEV_ADDR 0x5A

    I changed it to:

    #define OTG_1301_DEV_ADDR 0x58

    Also I made a note of:

    "SDRAM ***MUST*** be initialised for USB sample code to work"

    I only ever did this to test the circuit and some principles, it was not (and still is not) necessary for me to do anything further with the USB. You might like to follow them up though.

    As Andy suggested, you might want to contact Phytec about it - Or at least check their website. They have a few pages of FAQs about their boards.

    Yes, I have contacted Phytec and currently waiting on a response. I have had a look at their FAQs relating to this example (running on one of their other boards) but none of them seem to be relevant to this board.

    I had changed that device address but the SDRAM point is interesting, I will follow that up next.

    Thanks very much for your help, much appreciated.
