Nope, can't put the dongle on a RCC, because it is for comlinks. Something about how Riggers shouldn't be allowed to do anything with marks.
So basically Riggers are drek out of luck when theres a decker near by and starts putting marks on your RCC cause you cant even delete Marks off your RCC cause its a limit [attack] action and RCCs dont have an attack attribute best case you can reboot your RCC while drone are running and pray to the digital gods the Decker didnt reformat your RCC before hacking it to all hell
Also cause a Rigger using a RCC assumes a persona on the RCC he cannot slave it to a cyber deck for matrix protection so riggers are basically SOL unless they are slaved to a host which apparently doesnt break the rules
"There are also wide area networks, or WANs, with
multiple devices slaved to a host. This is the world of
that special kind of rigger, the security spider. They slave
their RCC to the building’s host and connect to the entire
security system, including all of its slaved drones. When
you’re inside a host, your effective “physical distance” to
drones slaved to that host becomes zero, even if you’re
on the other side of the world. The spider-rigger is often
teamed up with a spider-decker to help against hacking
intrusions on the security system"
