Describe the bug

I can't initialize anything, i cant do a damn thing.

Commands executed

$ liquidctl initialize all
ValueError: The device has no langid (permission issue, no string descriptors supported or device error)
$ liquidctl status
ValueError: The device has no langid (permission issue, no string descriptors supported or device error)

Output of all relevant commands with `--debug` flag

There (likely) are a few problems here:

The liquidctl driver needs to bail out from setting up the bulk device for LCD control if there aren't enough permissions to do (specifically, to read the serial number and pick the corresponding bulk device); we should use a similar mechanism than what we use for ASUS GPUs, allowing list (and possibly other commands independent from the bulk device) to continue to work.
The Linuxbrew formula probably doesn't install any udev rules since, IIRC, it hasn't been adjusted from the Mac one. Please verify and report this upstream, to Linuxbrew.
You need to fix your permissions. One way to do that is with the udev rules I mentioned in (2). In any case, check the Allowing access to the devices section from the README. Also be aware that AppArmor and other sandbox/confinement mechanisms may require additional, specific, configuration.

There (likely) are a few problems here:

1. The liquidctl driver needs to bail out from setting up the bulk device for LCD control if there aren't enough permissions to do (specifically, to read the serial number and pick the corresponding bulk device); we should use a similar mechanism than what we use for ASUS GPUs, allowing `list` (and possibly other commands independent from the bulk device) to continue to work.

2. The Linuxbrew formula probably doesn't install any udev rules since, IIRC, it hasn't been adjusted from the Mac one. _Please verify and report this upstream, to Linuxbrew._

3. You need to fix your permissions. One way to do that is with the udev rules I mentioned in (2). In any case, check the [Allowing access to the devices](https://github.com/liquidctl/liquidctl/#allowing-access-to-the-devices) section from the README. Also be aware that AppArmor and other sandbox/confinement mechanisms may require additional, specific, configuration.

Hey thanks for the reply. I took what you said and did some udev rules and i managed to get it fixed. I have a question thats out of scope for this thread though. I have a NXZT Kraken z63 aio and i cant figure out how to control my AIO. I am and to set the lcd screen to the liquid temperatures but nothing else.

Have you looked at https://github.com/liquidctl/liquidctl/blob/main/docs/kraken-x3-z3-guide.md?

I have not! Thank you for this, much appreciated!

You're welcome.

Reopening the issue because

'permissions-related issues setting up the bulk device' - this has peaked my interest; could this be a possible cause of discussion #621 ?
