This is yet another occasion of " Look! I've solved it! It works now.....errrr...Wait, no it isn't working after all".
That just confirms my summary of the overall observations a few posts ago.I fear that in order to really achieve a true solution, the actual root cause needs to be understood, not just assumptions made. To that end, I guess the best approach would be to analyze the USB stream on the physical bus.
That requires following things:
- Someone with a USB analyzer.
- Someone with USB expertise to understand the traces and identify what is going wrong in the stream.
- Someone with kernel USB know-how to track down the responsible code location and fix it.
I have none of the above things, though I had contemplated on buying a USB analyzer, just bcos I was frustrated that we are not making progress. But even if I would spend that much cash, I would still be lacking #2 & #3.
So, here's a new suggestion:
We all donate a number of bucks towards someone we identify as knowledgeable in #2 & #3. That person could then buy a USB analyzer from our donation and provide a true solution.
As reward for the effort, that person now owns a USB analyzer
Any thoughts on this?
I can contribute, i can put 50/100€. But Motu seems to be interested in solving the problem...
"Hi Piermarco,
I am sorry to hear about all the issues you have been having with linux. I am an engineer at MOTU and I have been working on and off with Takashi Iwai, the maintainer of the snd-usb-audio to try and improve our compatibility with the linux kernel. We have already made some changes made that were incorporated into the 5.11 kernel, but there are still issues for sure. I have been working on resolving those, but the work is still in progress. If you still have this hardware and can build and test kernel modules, would you be interested in testing some patches?
Best,
Dylan"
