USB Driver Troubleshooting

If connecting to our products via a USB cable, the PC must have a USB driver correctly installed. The USB driver files are included on the supplied installation CD, as well as the TRsSim software. If the TRsSim software has been installed, the USB drivers are normally located at:

C:\Program Files\Advent\TRsSim\Drivers

If a connection can not be established via a USB connection, the problem is either with the product itself or the installation of the USB driver. Use the following steps to check the status of the USB driver.

Note, the following procedure and screen shots apply to a PC running Windows XP.

1. Open the Control Panel window (click Start then Control Panel)
   
   
2. If in Category view: Click Performance and Maintenance, then click System.
   If in Classic view: Double click on the System icon.
   
   
3. From the System Properties window, click the Hardware tab.
   
   
4. From the Hardware tab settings, click Device Manager.
   
   
5. The Device Manager window provides information on the various devices connected to or are part of the PC. All devices are grouped by category. The category of interested is Universal Serial Bus controllers.
   
   

If the USB driver for our product is correctly installed, it will be listed in this category under the name of FTDI FT8U2xx Device.



If the driver has not been correctly installed but the connected product is working correctly, then the product name should be listed. In this example, the AI-5120 Telephone Line Monitor does not have a correctly installed driver.



To show more information, either double click the mouse on the listed item, or right click and select Properties from the popup menu. This displays a window similar to the following.



Use the following steps to reinstall the USB driver:

1. Click the Reinstall Driver button to display the Hardware Update Wizard.



2. Select No, not this time, and click the Next button.



3. Select Install from a list or specific location and click the Next button.



4. At this point, Windows needs to be told where to look for the driver files. Either insert the CD and check Search removable media, or supply the location of the drivers where the TRsSim software was installed by clicking on the Browse button. Then click Next.



After a few moments…



5. At this point the driver should be installed and the connected device can be used. Click Finish.
