I use a Dual PSX Adaptor. the exact device definition is the following:
009: ID 0810:0001 Personal Communication Systems, Inc. Dual PSX Adaptor
(check that by using $ lsusb)
I use jstest /dev/js0 and jstest /dev/js1 to test them but they behave very strange. If i press the Analog Button on one controller the little red LED lights up. For some reason i can’t have them both activated but only one at a time. now the buttons work even if the red LED isn’t shining, but the axes can only have the maximum/minimum values 3740 and -3740 and nothing in between. If one of the controller’s red LED shines though the axes can be precise and can have values between.
Did someone get 2 controllers to work with such a dual psx adaptor? maybie the reason is because i have 1x PS1-CTRL and 1x PS2-CTRL each ..
@mike you recommended using them, do they work for you?
OK I got it working. Reboot got it working in ES, then I found someone with the same issue and the solution was to manually edit the TwinUSBJoystic.cfg file with the same button assignment as a PS3 controller (minus the bottons a ps1 pad doesn’t have)
actually im not sure my previous cfg file modification did anything. I was originally using what i thought was port one on the usb adapter ps2 input and i switched to the other port and I think this is what got me results. I then have to presume I have the same issue as you with only one pad working. I don’t actually have a second to test them both at the same time.
