      Description

      PATH=src/gui/embedded
      FILE=qmousepc_qws.cpp

      class QWSPcMouseSubHandler_intellimouse : public QWSPcMouseSubHandler {

      int tryData()
      {
      if (nbuf >= packetsize) {

      //int overflow = (buffer[0]>>6)& 0x03;

      if (/overflow ||/ !(buffer[0] & 8))

      { badness++; return 1; }

      }

      Any reason why the variable int overflow is commented out and not used in the if statement check condition?

      I encountered a mouse wheel up overflow issue for intellimouse driver running on an Arm platform. I uncommented the code mentioned above and it resolved my issue.
