UPDATE: Aside from the dongle recognition issue, I just manage to do some trouble shooting...
Dongle 1024EC (SIUDI 5C):
Platinum 5R w/ Software version 1.1 works fine
Platinum 5R w/ Software version 1.0 works fine
Dongle 1024EC (SIUDI 5A, recognized 2048EC):
Platinum 5R w/ Software version 1.1 DOES NOT GET SIGNAL COMMANDS
Platinum 5R w/ Software version 1.0 works fine
Might the version 1.1 for platinum spot 5R be the problem??
