Scarlet Focusrite 2i2 not being recognised as a USB sound card

zoso · 2022-04-28 00:22:07

Hi all,

I'm new to Arch Linux and completely love it, I'm learning so much new stuff. I came from Ubuntu initially which I used for years. Ubuntu is great, but so much is handed on a plate to you that I didn't really need to learn quite as much. Still, beats Windows. Anyway, I got a bit stuck with my Scarlet Focusrite. On Ubuntu, I used it as an external USB sound card, partly because there were only third party drivers for the sound card I had in my laptop at the time, but also I just needed to record a lot of stuff so it was useful. Anyway...

I plugged it into my Arch system and it all lights up as it should but I can't seem to get it recognised as a sound card. I cant see it in pulseaudio or in the standard audio settings. I did do a bit of googling and found it might be related to a driver (snd?) but that's just a bit too far beyond my understanding to sort it alone without support from the community I'm afraid.

I don't even recognise it in the output of

lsusb

Once it's recognised as a sound card, I plan to use it to record and play back audio.

Does anyone have any ideas? I have a pretty basic understanding so thank you in advance for your patience but I am keen and love to learn so any input is appreciated (:

Thank you

If you plug it in, then look at what is printed to dmesg, it may provide some more information about what is happening.

V1del · 2022-04-28 00:34:05

If you can't see it in lsusb it's likely something more low level, maybe not enough power on the bus or so.

zoso · 2022-04-28 00:41:30

Hi @jasonwryan, thanks for that. I ran dmesg in a terminal (I think that's what I was supposed to do? sorry, noob here) and got this:

dmesg: read kernel buffer failed: Operation not permitted

@V1del Thanks for your input - how would I resolve this if this is the issue? I tried various different USB C cables and a couple of different USB ports and none of them gave a different lsusb output

jasonwryan · 2022-04-28 01:04:15

You need to run dmesg with elevated privileges.

V1del · 2022-04-28 09:25:22

Is this standard USB-C or actually a thunderbolt plug? Thunderbolt plugs need to enable some authorisation potentially: https://wiki.archlinux.org/title/Thunderbolt

But really to make a proper statement we'd need a dmesg.

Hi,

I have the same card which I use with Pipewire without any problem, or having had to set anything up. You can try switching to pipewire instead of Pulse audio.

that's irrelevant, the device does not exist as far as the system is concerned currently. Something has to be very wrong for a device to not appear in lsusb this is way before pipewire or pulse becomes remotely relevant (side info pipewire's device detection logic is directly copied from pulseaudio, they will generally run into the same problems in that regard)

makes sense...

for reference if it helps to compare, here are the outputs on my (working) setup, Focusrite 2i2 3rd Gen, with the provided USB A to C cable :

Greetings,

As it so happens, I am experiencing the exact same issue with the Scarlet Solo 3rd Gen. I know that the device is functional and the lights are on but its not recognized. Tried using different USB ports, and enabled the driver at module load time by adding the "device_setup=1" option to insmod/modprobe, however, that doesn't matter as the device isn't even showing up in the system.

Here's my dmesg:

I did some research but to no avail.
I wondered if they got it working as the thread just cut off rather unexpectedly. Unfortionally I am a bit clueless as to why the issue seems to occur primarily on arch. Under Debian-based distros it just happens to work without any problem.

If the OP found a solution to this or if anyone has any Idea on how to troubleshoot the given issue, please let me know.

Thank you and have a nice day.

[Edit]

Update: As it turned out, there actually was a problem with the energy supply on all the USB-A ports on my machine. Connecting it via a USB-C connector did the trick, although I could swear that it worked on the USB-A ports back when I was using it under Windows... however, it works now and this is all that matters.

I know this is an older post, but I registered specifically to say thank you for this update. This happened to me as well on a Dell Inspiron 5502 laptop. The built-in USB-A ports give enough power to light the device up, but I guess not enough for it to fully function. I have a USB-C dock that I was able to plug the interface into, which caused it to start getting recognized by the system and became usable. Thank you!
