My Windows 10 PCs got an update to 1903. After rebooting I started SDR-Console with no success.
Reason: The Update replaced the RTL drivers. Solution: running the ZADIG tool again.
I'm using an old Prolific 2303 USB to RS232 converter for my FT-100 CAT Interface.
You have to use an old driver version not the actual to get the converter running.
This was replaced as well.
(my driver package has this file name: PL2303_Prolific_GPS_1013_20090319.exe)
