OK, the error has something to with build having wrong vendor header, but after workardound works correctly. So the T1 fix is fine.

Noted the issue with vendor header in build in issue #2451.

USB packets have CRC and retransmission (except isochronous mode for real-time like audio), so data won't seem corrupted I'd think. Few times I've seen something was that device looked fine...

That shouldn't happen. The warning should go away when USB is in state "configured". Even with multiple chained USB hubs (like I have) that should be much less than a...

@TychoVrahe that is interesting, since I have exactly the same OS (Ubuntu 20.04 LTS), but probably different hardware, so we can guess the difference is in different USB controller, because...

USB be wild. There exists a great tool for debugging this, unfortunately even if ordered today, we'd get it in December soonest - https://www.crowdsupply.com/great-scott-gadgets/luna (though we might buy it because...
