Dear support team,
I’m really enjoying my Logic 8 pro, however, since I switched to linux 6.7.8 kernel version, anytime I try to start a capture, I get the “ReadTimeout” even in 1MS/s. Switching back to linux 6.3.x, without touching wiring, and everything works like a charm up to 250MS/s.
I haven’t found any previous topic related. Hope I’m not mistaken.
Cheers;

@akatopaz Sorry to hear that. It sounds like the newer kernel version you are testing changes something with regards to USB communication. For quick reference, the cause of ReadTimeout errors is described below.
In short, the newer kernel version may be limiting USB throughput somehow.
What Linux distro are you using? We develop and test our software on Ubuntu 18.04.5+ (64-bit).
Hey Tim,
Thanks for reaching out.
My distro used to be an ubuntu. But I’ve switched to devuan (daedalus currently). It’s worth noting that everything works like a charm. Except when I switch to newer kernels.
I build them so that there are no deps.
If I read you correctly, I’ll have to wait for some times before I can switch kernel. That’s fine. At least I do have some hints.
Cheers
@akatopaz Thanks for describing your setup. Based on the information you’ve shared so far, the issue does seem to point to your newer Linux kernel, given that switching back to a previous version completely resolves the issue.
I’m not sure if devuan / daedalus has something to do with the error either. Again, with regards to Linux, we only test and validate our software on Ubuntu.
Would you mind sharing your machine ID with us? Perhaps we can take a look at your uploaded error logs in case that helps us look into this for you as a starting point.
@akatopaz thanks for reporting this. We focus our testing on Ubuntu LTS releases that are still in their support window, so at the moment that’s just Ubuntu 20.04 and 22.04. A quick google search shows that 22.04 shipped with kernel 5.15 but I haven’t double checked my install yet.
Ubuntu 24.04 is coming out next month, and it looks like it will ship with Kernel 6.6.
We’ll see if we can do some quick testing with the daily build live image before it ships to see if there are any obvious problems.
Also, if there is a live image you can direct us to that uses Kernel 6.7, we can give that a try too.
Unfortunately we can’t publicly commit to much more than that right now. We’re a tiny team (3 developers) so we need to pick our Linux related battles carefully, given the enormous surface area of the Linux ecosystem.
Lastly, in the past, USB issues like this can sometimes be a combination of a specific kernel version and a specific USB host controller. (Back in the early days of USB 3.0 and the 3.x kernel, we saw a LOT of problems that were specific to certain host controllers)
Can you send us which host controller(s) you have? lspci -k prints out everything, you can either send it all or filter it down to just the USB host controller(s).
Dear @timreyes and @markgarrison
Bulls eye @Tim, clearly Daedalus has nothing to do with the error, as it works out nicely with a kernel change.
No problem for me that you only test with ubuntu as their distro is pretty solid.
I’m afraid I’ve not dug into distro that have a cutting edge kernel with a live image, I just grabbed this one Galileo Neo with Kernel 6.7.1, Plasma offline and Calamares fixes – EndeavourOS which can possibly fill the job.
About the tests, here is my machine ID : 60a75586-3ef3-46c9-9644-d08fd46af186, I hope it does not changes with the kernel or version of the sw.
I’m also willing to test any release you might have, and/or provide you with a .deb of my own kernel builds (6.7.x), they are tailored for intel laptops, but should definitely rock on regular intel desktops.

Regards,
@akatopaz Thanks for the link to a Kernel 6.7 distro! We’ll test out Kernel 6.6 first (Ubuntu 24.04) as a validation step before that releases. Afterwards, we’ll look into the distro you provided. I’ll provide updates again here.
