I dont really know much about electronics and I tried to seach online if this specific thing im thinking of doing has ever been posted and i cant find anything exactly the same.
So what im trying to do is make a makeshift powered usb hub. Ive seen several online but they are made differently. Basically, i wish to just connect the data + and - from the computer to the hub, disconnect vcc and gnd from the computer by cutting the ends of those wires coming from the pc, and finally connect a 5v 2a power supply from a tablet charger to the hub vcc and gnd.
Is this viable? I just thought this could be cool because since only the charger's power is connected to the hub, i wont need a diode since there is no possibility that voltage will be sent to the computer as that line is cut. Will this allow the pc to send data to the hub?
I hope this is not a dumb question. Thanks in advance!
