I thought USB routers were for devices, not PC connecting, which is by network stuff (NIC). I know squat but I'd guess you're connecting 5 volts on one PC to 5 volts on the other PC through the router, which trips the 5v current limit on USB of the PC.
I'm trying to setup a network between my two pc's with a router. The router is Ontop of one of the pc's across the room and the other is joines by a 5m USB extension to the router, everytime I plug in the USB Extension to the other PC it gets shut off, is it too much of a power drain?
