(a good reason for using RCC when you are a droner is that you can send instructions to multiple drones as one simple action if you use rcc and the drones are slaved to your rcc - you can also jump between drones without spending time to first jump out).
Strictly reading RAW let you slave your devices to your commlink but when you use your commlink for AR or VR it is no longer a device (it is a persona) and a persona can not be a master of a PAN.
...That you only connect your physical device with your physical commlink doesn't really hold water when you continue reading about WANs as there you connect your physical device with a Host - and host does not have a physical representation at all.
However, i firmly believe RAI is that you can (and even
should - they have multiple references to that) - slave your devices to your commlink or even better the team's cyberdeck even if they use the device to form their persona (what decker does not use his cyberdeck to form a persona anyway).
....it get kinda wired though... if your opponent can get hold of a wireless device you have slaved... and then establish a direct connection to it. by RAW he will get marks on the master... and if the master is now a persona... inside a host... well, i guess he would get marks on the persona... by remote. while he is inside a host. as i said, the concept get a bit strange...

....or maybe deckers are supposed to carry a commlink as well as a cyberdeck?
....that you are only supposed to benefit of the sleazes rating on the cyberdeck to run silent when the decker is not actually hacking anything (or running matrix overwatch from AR).
