The TASCAM US-122L, in previous versions of Ubuntu worked okay, with an occasional xrun reported by jackd, running with default settings (sample rate: 48000, frames/period: 1024). In Ubuntu 21.10 the device loads without problem, playback is perfect, but when the system load increases, it immediately crashes.
dmesg:
[ 218.607518] xhci_hcd 0000:00:14.0: ERROR unknown event type 37

Bus 001 Device 003: ID 0644:800e TEAC Corp. TASCAM US-122L
$ lsb_release -rd
Description: Ubuntu 21.10
Release: 21.10
Reproduction steps:
1) Start jackd
2) Start OBS with an USB webcam at 1080p
3) OBS monitor out goes to jackd/us-122L system port
4) Start Zoom, Thunderbird etc to generate some load
5) Immediately crashes
Crash occurs even quicker when adding and actively using another 4 channel USB audio device(same sample rate and period size). So the issue seems related to the load on the USB subsystem as well as the CPU load. I've tried just about anything to find out if the issue is hardware related. Changed cables, used different hubs, no-hub, used different USB ports on the laptop, etc, etc, etc. Same result every time. Also normal playback using PulseAudio instead of Jack suffers from the same. Each time a reset of Jack is needed to get the US-122L to work again.
I've tried, besides the default Ubuntu kernel(5.13.0-28-generic) the latest upstream mainline kernel(5.17.0-051700rc3-generic) as well as the low latency kernel (5.13.0-28-lowlatency). Same result.
If more information is needed, please let me know. Any help is much appreciated. Thank you in advance.
