Jstest not working

[vretro]

Hello, I wanted to find the name of an attached USB device, so I typed the following in Terminal:
jstest /dev/input/js0

I also tried replacing js0 with js1, js2, js3, etc.

I installed “Joystick” following the directions in the RetroPie wiki before I started.

I get the following error:
jstest: No such file or directory

Can anyone point me in the right direction, thank you.

If you don't have a /dev/input/jsX device, it means the device is not recognized as joystick/controller. What kind of device are we talking about ?
Run dmesg -w and plug in the device, the system log should give some indication if the device is recognized and configured.

@vretro Could it be using evdev-joystick? Can't remember the syntax offhand but my yoke controller is addressed this way and has a device id: event0, event1 etc.

@james-milroy Could be, but the cause is the same - the device is not recognized as a controller, but some other input device. Using evtest instead of jstest would list the input devices present and would let you pick which one to test.
