USB 2 Serial Driver (Virtual Com Port on Macintosh)

Hi everyone, I am using a product on Windows that uses RS232 communication, but the device is USB, so we are using USB 2 Serial Communication driver for the purpose. It works fine for the devices that we are using. What is there on Macintosh, that can provide the same functionality.

 

Thanks,
Kapil

    Hi,

    I am using a Mac for development, too. I use Serial2USB adapters from FTDI, they provide USB drivers for Mac as well. Have a look at http://www.ftdichip.com/FTDrivers.htm

    Hi Spachner,

    My device is not using FTDI chip set. Will the drivers would work? I think no. I am talking about usb 2 serial communication driver (similarily like umpusbxp.sys) but on macintosh. I am using Mac Mini that does not have any serial port.

     

    Thanks,
    Kapil

    When there is no OS X driver for your device it will not work natively under OS X. Think about using VMWare (or similar like Parallels) and a XP installation. I am doing this, too. Works great.

    I didn't develop any driver for windows also, using the driver umpusbxp.sys on windows with modifications in ini file for PID and VID, the device is working perfectly on windows. I need a similar kind of stuff on Mac. I think TI has something that can be related to umpusbxp.sys . Can you tel me what is umpusbxp.sys ?

    Probably I have not understood what you are doing correctly. It the mentioned "USB 2 Serial Communication" added by you or does the device come with a build in "USB 2 Serial Communication"? In the latter case you need a driver from the manufacturer for OS X. If it comes only with the umpusbxp.sys when it will just work under Windows. umpusbxp.sys is the USB driver specially written for Windows. I do not have certain knowledge about the umpusbxp.sys driver, so I cannot help further.
