The most common problem regarding the installation of USB devices

Notice

If you have any trouble with the following instructions, please send an email to support@dataq.com for further assistance.

Problem

When you run WinDaq USB, it comes back with the error message: "Could not open data acquisition device." Accessing your Windows Device Manager further reveals that with the DI-700 or 720/730/740-USB connected to a USB port of your PC, you cannot find the device listed. If the device is connected (and turned on for a 720/730/740-USB), it is probably listed under "Other devices" as "USB Device."

Common Cause

When a DI-7xx-USB is connected to your PC for the first time, Windows will detect it and ask for a device driver. (Under Windows 2000, you must be logged in as Administrator or have sufficient privileges to install device drivers.) If Windows cannot find a driver for the device and the user clicks the default button "Finish" or clicks on "Disable the device," the Windows Device Manager puts "USB Device" under "Other devices" and Windows will never prompt you again to install the driver. When installing in Windows XP, Microsoft issues a warning that the software "has not passed Windows Logo Testing to verify its compatibility with Windows XP." If the user stops Installation here, the Windows Device Manager puts "USB Device" under "Universal Serial Bus Controllers."

Without the proper driver, WinDaq will not run.

Solution

Insert the WinDaq Resource CD-ROM. If it auto-starts, click Exit. Then follow the appropriate directions for your operating system below.

Under Windows 98 or Windows ME

  1. Go to the Control Panel (Start>Settings>Control Panel) and open "Add New Hardware." The open window will instruct you to close any open programs. Do this and then click Next.
  2. Click Next again to have Windows search for any new Plug and Play devices on your system.
  3. Click on "Select USB Device" and click Next.
  4. Windows will report that the device has already been installed, but it has a problem. To view properties for the device and to see the problem and proposed solution, click Finish.
  5. Device status will show: "The drivers for this device are not installed. (Code 28)." To reinstall the drivers for this device, click "Reinstall Driver."
  6. When the Update Device Driver Wizard starts, click Next.
  7. Select "Search for a better driver than the one your device is using now. (Recommended)" and click Next.
  8. Under Windows 98, check the "CD-ROM drive" box and click Next.
  9. With di700.inf or di720.inf selected in the root directory of the CD-ROM drive, click Next or OK.
  10. After the wizard copies the files and builds a driver information database, click "Finish" for Windows 98 or "OK" for Windows ME. The DI-7x0 USB ADC Module Properties should be displayed. You can now close the wizard and close the Control Panel.
  11. Access the "Windaq" programs menu and open "WinDaq[7xx] USB0" to confirm that the device has been successfully installed. Always exit the application before disconnecting or turning off the device.

Click "Download device driver only," save the file to disk, and unzip DI700.ZIP or DI720.ZIP to a floppy. In the Device Manager, right click on the device and select "Update Driver...," remove the CD-ROM, insert the floppy, and click Next. In the "Files Needed" box, for "Copy Files From:", type "A:\".
  10. Access the "Windaq" programs menu and open "WinDaq[7xx] USB0" to confirm that the device has been successfully installed. Always exit the application before disconnecting or turning off the device.
