@sleve_mcdichael said in Oricutron key mapping - is it possible?:

It can be a lot to process. How far in before you got lost?

Look for an entry that represents your device. Scan for the line marked H: Handlers=, and make note of the event number. Example:

pi@retropie:~ $ cat /proc/bus/input/devices I: Bus=0003 Vendor=046d Product=c21f Version=0305 N: Name="Logitech Gamepad F710" P: Phys=usb-0000:01:00.0-1.2.2/input0 S: Sysfs=/devices/platform/scb/fd500000.pcie/pci0000:00/0000:00:00.0/0000:01:00.0/usb1/1-1/1-1.2/1-1.2.2/1-1.2.2:1.0/input/input73 U: Uniq= H: Handlers=event0 js0 B: PROP=0 B: EV=20000b B: KEY=7cdb0000 0 0 0 0 0 0 0 0 0 B: ABS=3003f B: FF=1 7030000 0 0 I: Bus=0003 Vendor=046d Product=c315 Version=0110 N: Name="Logitech Logitech USB Keyboard" P: Phys=usb-0000:01:00.0-1.2.4/input0 S: Sysfs=/devices/platform/scb/fd500000.pcie/pci0000:00/0000:00:00.0/0000:01:00.0/usb1/1-1/1-1.2/1-1.2.4/1-1.2.4:1.0/0003:046D:C315.0030/input/input74 U: Uniq= H: Handlers=sysrq kbd leds event1 B: PROP=0 B: EV=120013 B: KEY=10000 7 ff800000 7ff febeffdf ffefffff ffffffff fffffffe B: MSC=10 B: LED=1f

Truthfully? Here.

(But thank you very much for trying :))
