Hi all,
Here at SonTek we are aware of this issue and are working on gathering data and writing up a technical service bulletin (TSB). Our tech support group will distribute this TSB to all customers registered in our database. I will also post the TSB here once completed in the next few days. Until then, for those who have admin rights on their PCs I’ve attached instructions on how to change your FTDI driver.
Testing to date indicates the incompatible versions of the FTDI driver are v 2.14.1.8, 2.14.1.6, 2.14.1.2. These come installed on new Dell Latitude 5430 Rugged and Latitude 7330 Rugged Extreme laptops.
The most current driver provided on the FTDI website (v 2.12.36.4) works well. We recommend reverting to this version of the driver if possible.
