Problem with USB driver

I am trying to install the USB driver that came on the CD with my BOE bot to a Windows 98 computer. I went to the software section, but when I select the USB driver the word "install" on the button turns gray meaning it is not an option. Can somebody please tell me what is/I am doing wrong. Thank you in advance.

    It may be that the driver is not for Windows 98. Make sure you have 98SE since the earlier versions didn't have good USB support. I also recommend that you download a "fresh" copy of the driver from the manufacturer's website (or Parallax's) and make sure you have a version for Windows 98.

    I downloaded the driver from Parallax, but when I tried to open it I got an error message that said

    "The DPINST file is linked to missing export ADVAP132.DLL: ConvertStringSecurityDescriptionToSecutityDescriptorW."

    Does anybody know what I should do

    P.S. I only see one driver on Parallax's site.
    Also, are you saying that only certain versions of Win98 will work?

    Thanks

    Since I have this problem with the driver, could I use a Serial to usb converter to go from the computer's serial port to my BOE's usb port?

    (Although I would like to solve the problem through software)

    You cannot convert from serial to USB…It just won’t work. As for the driver, on the website it states, “Windows NY2000/XP only”. Windows 98 is not supported by that driver. If you want a Windows 98 driver you will need to download it from the FTDI website at the following link. We will be unable to support installation of this driver, however.

    Thank you very much for your help and the link, That was exactly what I wanted!

    Doesn't the stamp's FTDI chip change serial to USB?

    When I downloaded and unzipped the driver from FTDI's site I got the same files as when I copied them from the Parallax CD (Dec 2006 version, the driver on the CD says it works with 98).

    The files are:
    1) 906Releaseinfo.DOC 2) ftdibus.cat 3) Ftdibus.inf 4) ftdiport.cat 5) Ftdiport.inf 6) FTDIUNIN.exe 7) Ftdiunin.ini 8) ftsermoui.cat 9) Ftsermou.inf

    Usually an install wizard pops up when things need to be installed, but it did not. How can I install these files without the wizard/access the wizard to install this?

    Thank you in advance for any suggestions, I'm not really a computer expert.

    You need to go into the Device Manager and find the entries for the hardware that are not recognized. They will probably be under ‘Other Hardware’. The USB cable will need to be plugged in to see this. Double click on the entry and select the driver tab and then re-install driver. That should bring up the wizard. Take care.

    Hi all,

    Can I use USB-to-Serial cable for my Basic Stamp 2 ?
    My laptop doesn't have a serial port only USB.
    Thank you.

    If·you mean a usb caable to a USB to serial adapter, yes.· But, I think a serial connection is 12V and the stamp is 5V.· Check the stamp documentaion for a schematic to interface them.· If you are using a serial mdevelopment board like BOE or homework board I think that this conversion is built in.· Also, not all serial adapters will work, you might have to purchase one from parallax.· Lastly, make sure that you get the driver from the Parallax site.· If you are running Win98 then you have to get it from www.ftdichip.com.

    Yes, IF the USB to Serial cable implements all the hand-shake signals properly. Which means the cheapest "PDA" interface cables don't usually work. KeySpan, and FTDI, and Parallax all sell USB to Serial cables which work.

    And the BS2 implements 12 volt RS-232 to 5 volt BS2 signal conversion already on the 'programming port' DB-9, so you don't need to worry about that aspect. If you want to use SEROUT/SERIN to a PC on other BS2 pins, then you will need an adaptor with a MAX232 or equivalent to convert the BS2 5-volt signal to an RS-232 +- 10 volt signal. And another DB-9 connector.

    Thank you guys for your response.
    Sorry if I wasn't clear in expressing my problem..
    The scenario is this:
    Before, I use Serial Port to program and debug BS-2.
    But now, my new laptop computer comes with No Serial Port.
    This new laptop only have USB Ports.
    Now I'm not sure if I can use a USB-to-Serial cable for programming BS-2. cry.gif
    I'm only using the BS-2 chip alone, no other experimental boards.

    Hello,

    We carry a USB to serial adapter that can be used in place of a Serial Cable. Please see the link below. Take care.

    Go to pg 29 of the basic stamp manual ( http://www.parallax.com/dl/docs/prod/stamps/web-BSM-v2.2.pdf ) and it shows you the circuit for programming a bs2 with a serial port. It would be the same as the serial side of the usb to·serial converter.· You might need a·male to·male·adapter to plug the wires from the stamp into the cable.··It is pretty simple.
