You probably already saw the post from 2018, but did you try this?
Step 1: Right click on start menu and select device manager
Step 2: Go to Ports (COM & LPT)
Step 3: Delete all COM Drivers by right clicking on each one and selecting uninstall
Step 4: Restart Your System and Open Device Manager again to see Which COM ports appears (because some of the systems has multiple attachments attached that’s why multiple COM ports might appear)
Step 5: Download this driver package: https://drive.google.com/file/d/1MS1AHeaHXwG0DQmIWHlHhhbm4MExJdw9/view?usp=sharing
Step 6: Extract it and Run “ VCP_V1.4.0_Setup.exe ” (Make sure you run it as Administrator)
Step 7: After Installation, Connect your FOCBOX to the system
Step 8: Check Device manager if STmicroelectronics appear with COM PORT Number Under Ports (COM & LPT) note that number in your mind
Step 9: Run BLDC/VESC tool and select that COM port from the drop down which you’ve noted in your mind.
Didn’t work for me though
