[SOLVED] Streamdeck unable to open /dev/ device

I installed streamdeck-ui via the pip install instructions on the author's git page, and via the AUR package, but I am seeing the same behaviour either way.  When I launch it, I get an error saying:

A Stream Deck is attached, but it could not be opened.
Check installation instructions and ensure a udev rule has been added and loaded.
https://github.com/timothycrosley/streamdeck-ui

I did make sure the udev file was created when I installed via pip.  the AUR package installed the udev rule for me.  Either way, the result is the same. Also I see this in the system logs:

I do see the device with lsusb:

Bus 001 Device 014: ID 0fd9:0080 Elgato Systems GmbH Stream Deck MK.2

One curious thing I did notice is that as long as streamdeck-ui is running, the /dev/input/event19 device it is looking for doesn't exist.  However it does exist immediately before and gets re-created once I exit streamdeck-ui.

Don't do that.
The pip version of streamdeck-ui doesn't work well on archlinux when it's installed as user* partly because it interferes with systemwide settings.
It also clashes with the aur package and mixing them causes all kinds of issues.

Remove both, then decide which one you want to use : the pip managed version per user or the aur version sysemwide managed by pacman.

Whichever you choose : stick to your choice.




* installing stuff with pip systemwide on archlinux is a guarantee for problems.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

Re: [SOLVED] Streamdeck unable to open /dev/ device

Lone_Wolf, I had uninstalled the pip version before I installed the AUR version.  I didn't have both installed at the same time.  I'd rather use the AUR version honestly, and I'll stick with that for now.  I just need it to actually work.

Re: [SOLVED] Streamdeck unable to open /dev/ device

Fix your hostname, https://wiki.archlinux.org/title/Networ … e_hostname

the /dev/input/event19 device it is looking for doesn't exist

Do you know that because you checked the path or only from the error message?

ls -l /dev/input
sudo udevadm monitor

and attach the streamdeck.

Are you by any chance trying to run streamdeck-ui as root?

Re: [SOLVED] Streamdeck unable to open /dev/ device

Fix your hostname

My hostname is actually correct.  I manually changed it in the output for sanitization purposes

Do you know that because you checked the path or only from the error message?

Yes, I ran 

watch ls -l /dev/input/

in another terminal while I ran streamdeck-ui

ls -l /dev/input
sudo udevadm monitor

and attach the streamdeck.

Are you by any chance trying to run streamdeck-ui as root?

I am running streamdeck-ui as my normal user

Re: [SOLVED] Streamdeck unable to open /dev/ device

Sorry, the format made is look like to run ls before attaching the device but oc. it only makes sense while the device is attached.
Is your user in the "input" group? (Yes, should™ not be required w/ systemd)

Keep udevadm monitor running and start streamdeck-ui, does that trigger anything?
You can also audit access to the device file, https://wiki.archlinux.org/title/Audit_ … ies_access

I was not in the input group, so I added myself just in case and rebooted, but the result was the same.  This is what I see when I run 

sudo udevadm monitor

and then launch streamdeck-ui. These messages repeat every couple seconds. 

$ sudo udevadm monitor

I added an auditctl rule for /dev/input/event19, and this is what I see in the audit logs after I run streamdeck

Re: [SOLVED] Streamdeck unable to open /dev/ device

The device starts to flicker on access (disappears, reappears, disappears, reappears, …)
Can you try a different USB slot?

The audit (you posted) just shows the monitoring process (I think, if you want to be sure, match the PIDs)

Re: [SOLVED] Streamdeck unable to open /dev/ device

Not sure why I didn't think to try a different USB port.  That was it.  I switched to a different one and now it's working as expected.  Sorry for the waste of time and thank you for the assistance!
