Hi,
I want to design a pcb which will connect with a tablet (slave) either an Arduino PCB (host) and either with a PC (host). At the below image i took a senario where of a trouble shouting all devices will connect together (for instance because all relays are damge). My question is if and the three VDD of three devices (below picture) will connect parallel (two USB host devices parallel connected with a slave device-tablet) this will cause a damage to the devices or just there will not be a valid connection between them?
