    Intel NUC and USB?

    I am seeing a problem working with a Teensy 4.1 on an Intel NUC running a recent version of Win 10. Basically, I cannot connect to a T41 that was already programmed with an application that talks...

    I'm building grblHAL for Teensy 4.1 and seeing a problem that seems very similar to a problem that was discussed here some time ago. I think it may be related to this problem.
