Title: USB Switch for my logitech wheel going to my PC and PS2
Post by: SegaOutrun on February 28, 2014, 01:19:06 am
I need some input from people who know more than me regarding USB connections. Im using my Momo Logitech for my PC wheel and it is a ps2/ps3 compatible wheel and I am curious if something like this usb switch would work in my cabinet as an easy way to add more games without having to move the cabinet, unplug the wheel and replug into the ps2/ps3?

http://www.amazon.com/Plugable-One-Button-Swapping-Between-Computers/dp/B006Z0Q2SI/ref=sr_1_1?ie=UTF8&qid=1393567591&sr=8-1&keywords=usb+switch (http://www.amazon.com/Plugable-One-Button-Swapping-Between-Computers/dp/B006Z0Q2SI/ref=sr_1_1?ie=UTF8&qid=1393567591&sr=8-1&keywords=usb+switch)

it has one input and two outputs. My understand is that I need something that is passive (essential working only as an extension cable) and not something like a standard usb hub because it will not recognize the wheel.

Am i correct? Will this work? will something else do what i need? or am I SOL for (x) reason?

I can't really attest to this particular product, but if I were to make a switch I would just disconnect the ground and 5v line from the usb device not in use.  Even for passive usb devices, if that ground wire doesn't get a specific range of power back the device isn't detected.  The disconnection of the serial lines aren't nearly as important, because without power they can't really transmit anyway.

I think it should work... usb, for all it's mystery  is a 5v powered serial port, but the only way to know for certain is to try it.

Swoosh is a sound I heard over my head. But if Im reading it correctly, you giving it a "maybe". I looked at the questions asked page on amazon and some one said that they were using an ext hdd with this switch so it seem like it would provide enough power? or is that unrelated to what you say?

Well what I was getting at is how It probably operates is to kill the 5v and ground line connections on the pc not in use.  So it should be harmless to try but depending upon the wheel itself and how it operates it may or may not work. 

Every wheel I've ever seen gets it's power for the logic pcb via the usb port, so in theory when you cut those lines it should reset itself... but again it depends upon how the switch is constructed.
