FATAL: Module uinput not found.

[Wei Man Chim]

Hi guys,

I want to use my Playstation 4 controller (DS4) to control my Roomba. I thought the CI20 would be a good candidate, doing the interfacing of all.

So far I've managed to pair my DS4 to my ci20, this is done via bluetooth.
I want to use ds4drv, get a joystick device.
https://github.com/chrippa/ds4drv

But when run ds4drv, I'm getting the following error:
ci20@ci20-3374:~$ ds4drv
[error][controller 1] Failed to create input device: "/dev/uinput" does not exist or is not a character device file - verify that the uinput module is loaded

It seems that need to load up the module, but uinput cannot be found:
ci20@ci20-3374:~$ sudo modprobe uinput
FATAL: Module uinput not found.

so... at this point I'm stuck. Do you guys have any suggestions?

many thanks,
weiman

Hmm, as this is a kernel module my first check would be to see if it exists at all.  My CI20 is in a box right now and I have other pressing projects, but this might get you started.

https://unix.stackexchange.com/questions/184877/how-to-list-all-loadable-kernel-modules

If it does not exist, a kernel build might be in your future.  I know very little on the subject, so I may not be much help.

It's not looking good for me. I guess I need to compile something, I've no idea where to start
