Why isn’t my interface recognized by my PC?

We have seen some of these silently delete files or block the installation of files due to false positives through the software’s heuristic virus detection.

Try this first:
Connect the interface to another machine and check if it is possible to use it.

Then follow this procedure:

  1. Disconnect the unit.
  2. Uninstall the drivers using Control Panel
  3. Reboot the PC
  4. The logged in user on the PC must have Administrator rights for the remaining steps.
  5. Turn off any virus/firewall protection software. We have seen some of these silently delete files or block the installation of files due to false positives through the software’s heuristic virus detection.
  6. Download and install the latest driver version (5.26 2019-02-04)
  7. Connect the unit to a USB port and wait for the Found New Hardware wizard to complete.
