I have problem with USB OTG function on the AM3354 and Win CE 7.0, I don't need OTG function, only HOST.

Is it possible to disable the OTG functions in the Win CE 7.0 BSP and onyl support USB HOST ?

Thanks

    Hi, Steve


    Of course , you can do this.

    You can disable usb otg function through modifying the registry of usbotg.

    Best regards,

    Dear Steve,

    Greetings!!!

    Steve, no need to disable the OTG function. You can do one thing,
    Go to Drivers/USB/USBOTG/Resources and then open
    usbotg.reg file and comment usbOtg1.

    When driver will try to create the instance during the time of Initialization, it won't create any instance and in this way your USBOtg will be disable.
