Sometimes if you are not using a Profilic (probably spelled way wrong) original driver but a 3 rd party driver, you have to delete the driver and install the 3rd party driver.? This seems to happen to many almost? every time win 10 updates.

This may explain it.

I think my USB port drivers were changed.? When I try to run the KD8CEC Memory Manager or to upload a newly compiled? ubitx_20 version
I do not see the COM4 port any more. The Windows Device Manger shows an "Unusable Parallel Port (LPT3) where I previously saw a COM4
Serial Port.

Does anyone know what happened or how to undo it?
