    BusHound Get stall pid when host send "SET FEATURE" CTL command

    xixu_4093676

      When my fx3 device is tested for long time, I can observe number "stall pid" when pc host send "SET FEATURE" Control command.

      For detail, please refer to the attached for screen shot.IMG_4330.JPG

      But the SetupCB(CyU3vinUSBSetupCB) not been called, It seem like the API Library is return stall event.

      I just want to know what's cause the issues?
