The current driver for Freedom Scientific braille displays uses a DLL from FS to communicate with the displays. To benefit from upcoming improvements to NVDA's braille support such as autodetection (see #1271), a native implementation of this driver is prefered.

I started work on such a driver in the branch at https://github.com/bramd/nvda/tree/freedomscientific-native.
