    KBA228228 with AN75779: This device cannot start. (Code 10)

    LeGa_3963206

      Hi all,

       

      I'm trying to add multiple FPS values to Uncompressed VS frame descriptor as described in KBA228228 but id doesn't work - device manager reports "This device cannot start. (Code 10)".

      According to serial log output it not even get to probe get/set stage.

       

      Here is my SS descriptor:

      const uint8_t CyFxUSBSSConfigDscr[] __attribute__ ((aligned (32))) =

      {

          - In this descriptors the descriptor size should be according to the Macro enabled so please add for descriptor size as done after Default frame interval i.e descriptor size should be 0x1E for one fps and 0x2A for 4 fps.

          -  Also, the  multiple fps defined in descriptor should be in decreasing order

           

          Please let me know if any queries on this

            Hi Rashi,

             

            The decreasing order solved the problem

             

            Thanks a lot!
