HIDpath error

[justTravis]

I am getting the following error:

I have a Logitech G910 keyboard.

This is a new one, I have never seen this error before :V

It did work for you in the past, can you maybe say a bit more about when this happened? Did you unplug the keyboard or go to sleep / hibernate?

[justTravis]

I added myself to the "docker" group so I wouldn't have to sudo docker commands. It didn't seem to work, so I rebooted to see if it would, and it did, BUT.... this error appeared with keyboard-center.

Docker was already installed, I just wasn't in the group to allow using it without sudo.

[zocker-160]

Can you please check with id command in terminal, that you are still part of the plugdev group?

The exception above is a bug, it should show a proper error message, but libhidraw not working is a permission issue on your side.

[justTravis]

hmmm, no I am not.

and the group doesn't even exist - should I just manually add it and then add myself to it?

[zocker-160]

If the group does not exist, then creating it will probably not fix the issue.

Can you check if running as root also gives that error? If not then this is 100% a permission issue.

Please check that the udev rules are still in place. I sadly do not know why docker would break something like this, but it did work in the past, so something took away the read permission from your user.

You could also try reinstalling as the install does trigger udevadm, so it could fix it.

[justTravis]

sudo gives the same error. I tried uninstalling and reinstalling, no dice.

[zocker-160]

Did you install any other software which does access keyboard?

I need the output of sudo ls -l /dev/hid* and sudo evtest

[justTravis]

I didn't install anything in between when it worked and when it stopped working. I do have another piece of software called input-remapper that works with a Razer Tartarus, but it has never interfered before that I know of.

The output of the ls command is: crw-rw----+ 1 root root 240, 0 May 17 16:44 /dev/hidraw0 crw-rw----+ 1 root root 240, 1 May 17 16:44 /dev/hidraw1 crw-rw----+ 1 root root 240, 10 May 17 16:44 /dev/hidraw10 crw------- 1 root root 240, 12 May 17 16:44 /dev/hidraw12 crw-rw----+ 1 root root 240, 2 May 17 16:44 /dev/hidraw2 crw-rw----+ 1 root root 240, 3 May 17 16:44 /dev/hidraw3 crw-rw----+ 1 root root 240, 4 May 17 16:44 /dev/hidraw4 crw------- 1 root root 240, 5 May 17 16:44 /dev/hidraw5 crw------- 1 root root 240, 6 May 17 16:44 /dev/hidraw6 crw-rw----+ 1 root root 240, 7 May 17 16:44 /dev/hidraw7 crw-rw----+ 1 root root 240, 8 May 17 16:44 /dev/hidraw8 crw-rw----+ 1 root root 240, 9 May 17 16:44 /dev/hidraw9

And the output of the evtest is: No device specified, trying to scan all of /dev/input/event* Available devices: /dev/input/event0: Sleep Button /dev/input/event1: Power Button /dev/input/event10: HDA NVidia HDMI/DP,pcm=7 /dev/input/event11: HDA NVidia HDMI/DP,pcm=8 /dev/input/event12: HDA NVidia HDMI/DP,pcm=9 /dev/input/event13: python-uinput /dev/input/event14: Valve Software Steam Controller /dev/input/event15: HID 0c45:7403 /dev/input/event16: HID 0c45:7403 /dev/input/event17: Razer Razer Tartarus V2 /dev/input/event18: Razer Razer Tartarus V2 Keyboard /dev/input/event19: Razer Razer Tartarus V2 /dev/input/event2: Power Button /dev/input/event20: Razer Razer Tartarus V2 /dev/input/event21: Logitech Gaming Keyboard G910 /dev/input/event22: NexiGo HD Webcam: NexiGo HD Web /dev/input/event23: Kingston HyperX Cloud Stinger Wireless Consumer Control /dev/input/event24: Kingston HyperX Cloud Stinger Wireless /dev/input/event25: Kingston HyperX Cloud Stinger Wireless /dev/input/event26: Kingston HyperX Cloud Stinger Wireless /dev/input/event3: Eee PC WMI hotkeys /dev/input/event4: HDA Intel PCH Front Mic /dev/input/event5: HDA Intel PCH Rear Mic /dev/input/event6: HDA Intel PCH Line /dev/input/event7: HDA Intel PCH Line Out /dev/input/event8: HDA Intel PCH Front Headphone /dev/input/event9: HDA NVidia HDMI/DP,pcm=3

Thank you so much for the effort!

[zocker-160]

I pushed a new version, it will not fix your issue, but it should fix the broken error message.

As for your issue, I need even more information, as the shown above looks ok to me, can you pls provide the output of this script (run as user, not root):

#!/bin/bash

FILES=/dev/hidraw*
for f in $FILES
do
  FILE=${f##*/}
  DEVICE="$(cat /sys/class/hidraw/${FILE}/device/uevent | grep HID_NAME | cut -d '=' -f2)"
  printf "%s \t %s\n" $FILE "$DEVICE"
done

It maps the HID endpoint to a physical device, this one should show which endpoint is related to the G910 keyboard.

[justTravis]

I installed the new version and as you said it still fails. The error message is now: [root] ERROR: 18.05.2023 07:41:00 AM Traceback (most recent call last): File "/usr/lib/keyboard-center/main.py", line 52, in window = MainWindow(app, devmode, not bgmode) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/keyboard-center/mainUi.py", line 68, in init self.initBackgroundService() File "/usr/lib/keyboard-center/mainUi.py", line 153, in initBackgroundService self.service = BackgroundService(self.configparser, not self.devmode) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/keyboard-center/service.py", line 85, in init self._initKeyboard() File "/usr/lib/keyboard-center/service.py", line 126, in _initKeyboard self._getHIDpaths() File "/usr/lib/keyboard-center/service.py", line 171, in _getHIDpaths raise NoEndpointException() service.NoEndpointException Traceback (most recent call last): File "/usr/lib/keyboard-center/main.py", line 52, in window = MainWindow(app, devmode, not bgmode) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/keyboard-center/mainUi.py", line 68, in init self.initBackgroundService() File "/usr/lib/keyboard-center/mainUi.py", line 153, in initBackgroundService self.service = BackgroundService(self.configparser, not self.devmode) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/keyboard-center/service.py", line 85, in init self._initKeyboard() File "/usr/lib/keyboard-center/service.py", line 126, in _initKeyboard self._getHIDpaths() File "/usr/lib/keyboard-center/service.py", line 171, in _getHIDpaths raise NoEndpointException() service.NoEndpointException

[zocker-160]

Thanks for the output, yeah there is a bug somewhere which prevents the script of finding the right endpoint, which is weird since it seemed to be working in the past.

Also could you send me your log file? (should be located in ~/.var/log/keyboardCenter.log)

I sadly am a bit out of ideas, I need to add a more logging to find out what is going on.

I know it might sound weird, but could you try to reboot without the Steam Controller plugged in?

I have a suspicion that I have a bug in the code which fails to detect the keyboard when the hidraw id is > 9

[justTravis]

hmmm I can't reboot just yet due to I'm in the middle of meetings at work. but I will later! and here is the log you asked for.

keyboardCenter.log

[zocker-160]

Ah this log is very useful. So the problem is, that it fails to find a read endpoint and only find the write one. This is further evidenced by the fact that in your output above it does indeed only list one endpoint instead of two.

Now my first reaction would be to guess that your keyboard only uses one endpoint for both (which some do), but since it did work in the past for you means that something has changed in the way the keyboard registers in the system, which is really weird....

[justTravis]

sadly the "reboot without the steam controller" didn't help.

I re-ran the script you gave and got this output: hidraw0 HID 0c45:7403 hidraw1 HID 0c45:7403 hidraw2 Razer Razer Tartarus V2 hidraw3 Razer Razer Tartarus V2 hidraw4 Razer Razer Tartarus V2 hidraw5 Logitech Gaming Keyboard G910 hidraw7 Kingston HyperX Cloud Stinger Wireless

and running (as sudo) the keyboard-center app shows this: [root] ERROR: 19.05.2023 07:03:33 AM Traceback (most recent call last): File "/usr/lib/keyboard-center/main.py", line 52, in window = MainWindow(app, devmode, not bgmode) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/keyboard-center/mainUi.py", line 68, in init self.initBackgroundService() File "/usr/lib/keyboard-center/mainUi.py", line 153, in initBackgroundService self.service = BackgroundService(self.configparser, not self.devmode) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/keyboard-center/service.py", line 85, in init self._initKeyboard() File "/usr/lib/keyboard-center/service.py", line 126, in _initKeyboard self._getHIDpaths() File "/usr/lib/keyboard-center/service.py", line 171, in _getHIDpaths raise NoEndpointException() service.NoEndpointException Traceback (most recent call last): File "/usr/lib/keyboard-center/main.py", line 52, in window = MainWindow(app, devmode, not bgmode) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/keyboard-center/mainUi.py", line 68, in init self.initBackgroundService() File "/usr/lib/keyboard-center/mainUi.py", line 153, in initBackgroundService self.service = BackgroundService(self.configparser, not self.devmode) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/keyboard-center/service.py", line 85, in init self._initKeyboard() File "/usr/lib/keyboard-center/service.py", line 126, in _initKeyboard self._getHIDpaths() File "/usr/lib/keyboard-center/service.py", line 171, in _getHIDpaths raise NoEndpointException() service.NoEndpointException

[zocker-160]

Thank you for this, so my original suspicion did not materialize. I will create a special debugging build for you.

I would however be interested in the following output to see what kernel log says while registering the keyboard: sudo dmesg | grep G910

[justTravis]

that command returns nothing. if I ignore the grep and just scan the output there is no mention of the G910 or Logitech or anything identifiable to me.

as a side note. I am now dual booting into ArcoLinux and it works fine even with all updates. But I experimented with a few other distros, and it is worth noting that NONE of the debian flavors work. Kubuntu, Mint, MX, and some others... I've not yet seen the .DEB file work at all. This is what is keeping me on Arch based distros even though I think I may not be the target audience for the instability.

[zocker-160]

that command returns nothing. if I ignore the grep and just scan the output there is no mention of the G910 or Logitech or anything identifiable to me.

This is weird, I am so confused. On all of my machines I can see how the keyboard is being detected and registered in the hidraw system by the kernel. It should look something like this:

Regarding the deb, it is build for Ubuntu LTS and I am personally running it on Kubuntu. Do you have any error etc when trying to run on Ubuntu LTS? I hope I have not messed up the deb, but it does install fine for me.

I cannot speak of derivates like Mint or MX as it would be very time consuming having a test setup for all of them.

[zocker-160]

Did you manage to make it work or is there a way I could help to debug the issue?

[justTravis]

I switched to Arco Linux and to XFCE and it's working fine. Some games run less well than they did on Garuda but keyboard center works so that's a better deal for me :) I have just started a new job so have not yet had time to make a side install of Ubuntu or any Debian based system to test again with. Now that I'm reading this again, I recall I do have a laptop around with Kubuntu. I'll try to give that a shot today.

[justTravis]

It is working fine on my Kubuntu. It seems like the problem is one-off on my particular Garuda installation :( Probably not worth more of your time. I do very much appreciate your efforts though!

[zocker-160]

thank you for testing!

closing this issue then
