Permission issues on RPi

[PMK]

I'd like to use my good old Logitech Formula Force EX (Product ID: 963357-0914 , Link, red PC-Wheel, 12 buttons, two pedals) to my PS4 via Gimx 6.9.1 "Stretch" on a RPi3 running Raspbian Stretch.

I've installed everything using this tutorial and tried some of the hints posted here.

Despite many attempts I still have problems with the permissions.

Code: Select all

libusb/gusbhid.c:480 claim_device: libusb_open failed with error: Access denied (insufficient permissions)

seems to be fixed but

Code: Select all

linux/uhidasync.c:249 guhid_create: open failed with error: Keine Berechtigung

still causes headache...

It would be great if one of you could check what needs to be done to make it work.
Thanks a lot in advance!



Here you will find some more detailed information from my console:

[Matlo]

You can safely ignore these messages for gimx-launcher.

[PMK]

I'd love to. But everytime I press the "Auto-detect" button in the config editor, the editor window freezes with the auto-detect button pressed.
Could this issue be related to the "insufficient permissions" error message?

The notification that the controller was not found is a minor problem but but I'm worried about the immediate freeze on auto-detect.
The wheel is powered and connected as well as the powered off DS4.

[Matlo]

Error message says "Resource is busy". This very likely refers to your wheel. Another app must be using it.

[PMK]

Could this be another instance of GIMX? For example, if I start GIMX according to the tutorial automatically at boot and also via SSH (to get the UI via Putty)?
And could this be the reason for the freeze when I try to auto-detect the device in the configuration editor?

What I can help to simplify your troubleshooting, for which I thank you very much.

[Matlo]

Absolutely. You should kill it to have appropriate access to devices. It is not a valid use case to use the config editors while gimx is running.

[PMK]

Sounds plausible.

I would prefer to disable autostart of GIMX.
Is that's the right way to do?

Code: Select all

sudo systemctl disable gimx

[Matlo]

Yes, this will disable it if it is run as a service. Maybe you also need to stop the service (replace 'disable' with 'stop').

[PMK]

We are getting closer:

After tweaking my configuration (my "EX" wheel was detected as "RX"), I can say that everything works like a charm.

Not sure why "chmod 666 /dev/uhid" changed anything because I did it yesterday already.

Thanks for your great support and GIMX.
