so, yes, as far as the input system is concerned, they're the same type of device.
Think I'm going to rewire them - not too hard, the wiring harness has pins I can just pull out and shove into another spot - will just have to figure out what goes where and remember the original layout if I ever want to put it back lol. Thanks for the help though.
On a related note: is the USB controller device order no longer implemented in RetroPie anymore? Seems like the Xbox wireless adapter is superseding anything physically plugged in on a lower USB port number, or maybe I have to reboot and test that again? (i.e. not hot swappable? - I forget if it ever was TBH).
And yes, I'm quoting myself and looking for confirmation on this. Seems like on the RP3 when all 4x USB's were 2.0, the order was something like left bottom 0, top 1, right side bottom 2, top 3.
On the RP4, I think (NOT positive, would like confirmation if possible), they run separately for the USB 2.0 side and the USB 3.0 side. I had my WIRED fightstick plugged into the left side #1, which should have superceeded the 3x WIRELESS fightsticks which were plugged into #2, but I think because the wireless was on the 3.0 side that superceeded the 2.0 side in controller order. Right now I have the wired fightstick plugged into the right side top, and the wireless 360 dongle on right side bottom and the wired one is player #1, and the wireless are #2/3/4. can anybody confirm this is how it works now on a RP4?
