I have managed to hook up and utilize a HIMS Syncbraille display with NVDA on my laptop, and even a few tablets using NVDA 2020.3. But it will not run on my desktop pc.
I installed the drivers recommended on the user guide of NVDA, but nothing is happening.
I don't see specific display drivers listed in Braille settings for HIMS any longer as in prior versions of NVDA. So I have selected automatic. This works with the laptop etc. But nothing on the PC. Odd thing is that I can get the native windows screen reader to see it and work with it on it.
