    • USBH initialized with CDC device driver failed to detect device description.

      Hi,

      Recently we tried porting the eval software of embUSB- Host from ATMEL SAMA5D3-Xplained board to ATMEL SAMA5D3x-EK .
      We have created the project in IAR EW 8.2. we merged the USBH & USBH_CDC driver start script to a basic embOS project.
      When we tried to run the project we are getting USB host controller initialized and device driver initialized, but when i connect a cdc device like mouse or keyboard i am getting error messages like

    • Hi Santhosh,

      the Eval version is not designed to run on the EK board.
      Furthermore - mice & keyboards are usually not CDC devices.
