I received my programming cable from Radioddity today. Cable information is: Model: PC002; SKU: 715-RP-PC002; IC: CH340C; Length: 100cm. I have checked all my connections and communication port settings. Device manager shows port 8. I put port 8 into the software comm port box, but the software returns the message: "Please check all connections and communication port settings". My windows 11 Laptop (bought early this year) is up to date on all software updates. I do not know what else to do. I have followed all the suggestions about turning off/on systems, etc. Nothing seems to allow the laptop to communicate with the Radioddity GM-30 radio for programming it. Has anyone encountered this problem or have any suggestions I can pursue?
