Do you need a usb if you just want to watch plugin channels?



Hello there

I have a NETGEAR nighthawk x10 and the plex server can be added from the admin dashboard but I am unsure if I need to plug in the usb straight away to the router or if it’s only required to access libraries of media?

Also does the usb/ hard drive need to be empty for the plex setup?

Thanks in advance.
