  • Try this, replace this line:

      strCmd = "net use lpt1 \\"& strComputerName & "\"& PrtName & " /persistent:yes /YES"


      strCmd = "net use USB02PORT lpt1 \\"& strComputerName & "\"& PrtName & " /persistent:yes /YES"

    see where I added the usb port?

    and or try USB002PORT

    Or is this what you want?

      strCmd = "net use USB002PORT USB001PORT \\"& strComputerName & "\"& PrtName & " /persistent:yes /YES"
