Hello,

I don’t know if this can be useful here:

I own a X-Arcade Dual Joystick with a serial-to-USB adapter (yeah, more than 10 years of service)
When I use it without Xarcade2Jstick on RetroPie, it’s recogniced as a keyboard, when the service is up, it does nothing.
The system is Raspbian Jessie lite with Retropie from github after fresh install.

pi@arcade:~ $ sudo lsinput

Made some test with strace on xarcade2jstick and he gets exclusive access to /dev/input/event0 as shown in lsof:

xarcade2j 448 root 4r CHR 13,64 0t0 1848 /dev/input/event0

shows intercepted data after using the xarcade device with this error after pushing UP in left joystick:

Hope it helps
