    UVC extension class

    alex.j_1416716

      Hi,

         

      I am very new to  cypress FX3 and UVC and currently i am working on UVC Extension unit feature.

         

      In PC side i am using AMCap player (windows).

         

      my question is -

         

      By changing the extension unit descriptor, will it work with AMCap player?

         

      If yes , what  changes are required in above descriptor ?

         

      I also confused with  GUID for extension unit. whether it should match with player side GUID ?

         

      thanks in advance.......

          For XU (extension unit), GUID from both side should match each other.

             

          we can implement a number of XU for a single device with different GUIDs.   Using GUID and terminal ID (windex) , we can identify corresponding XU.

             

          In player side, user should add additional plug-in to invoke XU. This plug-in should verify corresponding XU GUID.
