Faulty or intermittently working USB Dongle

If you're experiencing issues with your Trimble Business Center (TBC) USB dongle, such as it not being recognized or working intermittently, you can follow these steps to troubleshoot the problem:

1. Check Dongle Connection.
   First, ensure that the dongle is properly connected to a USB port on your computer.

   • Test on Another Machine.
     To rule out issues with drivers or ports, try testing the dongle on a different machine. This will help to determine whether the issue is specific to your computer.

   • Check Dongle LED Status.
     The LED on the dongle provides valuable information about its status. If the dongle is operational, the LED will typically emit a steady light. If it's blinking or not lighting up at all, it could indicate a problem.

   • USB Ports Check.
     Verify the functionality of your USB ports by connecting other devices to them. This can help identify whether the issue is related to the port itself.

2. Update Dongle Drivers.
   Download and install the latest Sentinel LDK drivers for your USB dongle. You can find these drivers on this page under the Sentinel LDK runtime drivers section. Download the latest Sentinel HASP/LDK Windows GUI Runtime Installer.

3. Refer to Troubleshooting Guide. 
   For more in-depth troubleshooting, refer to the HASP troubleshooting PDF provided by Trimble. This guide can be downloaded below and may contain specific steps to address common dongle-related issues.

4. Check Maintenance Agreement.
   If your dongle is found to be faulty and needs replacement, please note that replacements are typically covered under an active maintenance agreement. Make sure to verify the status of your maintenance agreement before proceeding.

   By following these steps, you can diagnose and potentially resolve issues with your USB dongle's functionality. If problems persist, contact our support team for further assistance.
