Thank you very much Kevin for this finding regarding the USBAUTO=¡±false¡±.
It fixes exactly my problem with my Pi4, GPS dongle ublox7 and IC-7300 & 7100 radios for CAT control.
Indeed I dont understand why gpsd attach pps1 and pps2 to /dev/ttyUSB0 and 1 (which overrides the CP210x UARTS in the? ICOM ).
