USB is a (quite complex) master-submaster-slave protocol with each device negotiating for speed and bandwidth with the one 'above'. The electronics of a USB hub shares out the bandwidth it is offered to its slave ports and must talk to its master through the input port/cable, in this case the C socket. The (sub-)master in a PC must connect to the hub and its slaves through the designated input cable, it cannot talk to other slaves while plugged into one of the slave ports. -- Joe
