0.2.2. --- erratic behavior

[LittleCannon]

Describe the bug After daemon is started and X52Pro connected, on display, mode status (1,2, 3) starts rapidly blinking. Also in game X52Pro is erratic ( it feels like it is repeating inputs, rather then holding constant value).

To Reproduce Steps to reproduce the behavior:

1. Just start x52d 0.2.2
2. take a look at LCD display
3. Blinking mode status number
4. Soon as x52d is stopped, hotas is working normally.

Expected behavior Normal behavior

Screenshots If applicable, add screenshots to x52evtest-output.txt help explain your problem.

Environment (please complete the following information):

• OS: Debian Sid
• libusb version: libusb-1.0
• X52 type: Bus 001 Device 004: ID 06a3:0762 Saitek PLC Saitek X52 Pro Flight Control System

Additional context In attachment x52evtest output,without touching hotas. It starts soon as hotas is connected.

As of version 0.2.2, the daemon doesn't do anything but control the brightness, clock and LED states. The mode status number is also controlled in hardware, not by the daemon. I'm not sure why you are seeing the problem only when running the daemon.

Can you also attach the x52d logs? If you are using the released .deb package (or if you've built from source with the default configuration), then you'll need to edit /lib/systemd/system/x52d.service, and update the ExecStart line from -v to -vvvv. Then you can capture the logs by running sudo journalctl -b -u x52d.service.

If you're running the service manually, then you can append -vvvv -l /tmp/x52d.log, and attach that file.

[nirenjan]

Also, without starting the daemon, can you capture x52evtest output? Also, please run x52test led - this is a program which will exercise the hardware (just the LEDs) and make sure that the device is working as expected. The output that you attached is showing flapping on the MODE_3 button, which leads me to think that either the button sensor is not working as expected, or (more likely), the PS/2 cable connecting the throttle and stick is bad. I had to replace the cable on my own joystick several years ago, and I suspect that this might be the more likely reason you are seeing issues.

[LittleCannon]

Tnx for really quick reply

My first thought was also that switch or even cable might be faulty, but as you can see from evtest with daemon stopped, it is not.

Please let me know if I can do anything more to assist.

[LittleCannon]

oh, I forgot, I've built it from source.

[nirenjan]

OK, unfortunately, the journalctl logs are getting cut off, can you please capture the output using sudo journalctl -b -u x52d.service > journalctl_log.txt and attach that output please?

[LittleCannon]

journalctl_log.txt

[nirenjan]

Huh... the journal logs are showing an error which was fixed before I released 0.2.2, what commit are you at?

[LittleCannon]

I downloaded source from latest release. 0.2.2. I guess?

Also I tried with deb package as well. Same thing.

[nirenjan]

I think I may have found the issue. Can you try with the latest commit on branch check-device-attached and see if you still see the problem?

[LittleCannon]

You got it! It works as expected now.

Thank you very very much!

[nirenjan]

Thank you for the confirmation. If you can provide the verbose daemon logs when unplugging and reinserting the X52, I'd appreciate that very much.

[LittleCannon]

Of course!

Here it is. journalctl_log.txt

[nirenjan]

Thank you. One last request - can you share the contents of libx52/x52_stringify.c? The log messages that you shared indicate another fault which I thought I fixed in that file.

[LittleCannon]

Yes no problem.

Oh btw, if I can assist more, please let me know. Really it is no trouble for me.

Thank you, if I need more help, I'll raise a separate discussion and tag you.
