BMW Nav VI not recognized using macOS Big Sur with BaseCamp v4.8.12.

I recently purchased a new MacBook Air that runs macOS Big Sur, version 11.6.  I installed the latests version of BaseCamp (v 4.8.12), but when I hooked up my BMW Nav VI GPS via USB, the GPS unit isn't recognized so I could transfer routes.  Had to use my old Mac and old version of BaseCamp to transfer the GPX file.  Is there ia fix for this?
