This question already has an answer here:
I've got a WiiU/Swtich GameCube USB adapter that I'd like to plug into my computer (device 1) as well as my Nintendo Switch (device 2) and have both devices recognize that USB adapter and the controller plugged into it.
I have seen some products that allow you to switch between the two devices but they won’t work for what I'm trying to do unless I can trick it to broadcast data to both connections. It is not advertised on box as a feature so it is probably not possible.
Those switches look something like this Kensington ShareCentral 2 (K33900US) and can be picked up for $9 to $20 bucks at my local Fry’s electronics shop:
I was reading up on folks with similar situations and ran into this other Super User post, “Connect USB storage device to 2 computers at a time.” not exactly what I'm trying to do but it had lots of good information including this possible solution from @UğurKırçıl using 2 spliced USB wires.
Thats so simple -if you know a little bit soldering- first get one female usb socket then get two usb cable solder two cables GND,DATA+,DATA- pins together solder 2 piece diodes for 2 cables + pin then connect flash drive to female socket and connect 2 cables to 2 pc NOTE 1 : why we use diode , because we didnt want burn anything NOTE 2 : NEVER OVERLOAD FLASH DRIVE IN THIS MODE
Well I do know some soldering and the guy at Fry’s seemed to think it could work. He also suggested splitting the USB on the GameCube adapter and going that route.
So my question is the above answer describes a solution that would splice 2 wires together to produce a single female end and a 2 pronged male side. Would this cable configuration properly transfer USB data to both devices that it is plugged into? Why not do something like this if I have all the kit? Anything glaringly obvious I'm overlooking with USB 2.0 vs 3.0?
I also noticed that the answer shown above seems to only reference a few of the cables in the USB 3.0 diagram. So I am ssuming this description is for USB 2.0?
