    Standard UVC control

    wallace.tseng

       Hi,

         

      I'm trying to send standard control requests such as brightness adjustment via AMCAP.

         

      I've modified PU descriptor for supporting brightness control..

         

      After adjusting brightness in AMCAP, I suppose there should be a callback sent to CyFxUVCApplnUSBSetupCB but I got nothing.

         

      The only callbacks are received while UVC initialing those are GET_INFO, GET_MIN, GET_MAX, etc.

         

      May I know is there any thing I missed and what value should I return to host when receiving GET_INFO?
