snd_usb_audio: Logitech USB Headset Causes Softlockups During Meetings

[Matthew Ruffell]

[Impact]

I have a Logitech H340 USB Headset and a Logitech C270 Webcam I use for meetings.
I access Google Meet with Firefox.

During a meeting, or immediately after one, and especially so if I join a second meeting after one finishes, my input devices start acting up and my system becomes unstable.

Things start with my Headset getting reset:

[ 3153.811599] usb 3-3: reset high-speed USB device number 2 using xhci_hcd

This happens multiple times.

Then I get a long list of suppressed callbacks:

[13468.808356] retire_capture_urb: 133 callbacks suppressed

From there, things timeout and I get this stack trace:

hid-generic 0003:046D:0A38.0005: input,hiddev2,hidraw4: USB HID v1.11 Device [Logitech Inc. Logitech USB Headset H340] on usb-0000:06:00.0-2/input3

This is then followed by:

[14262.566484] xhci_hcd 0000:06:00.0: ERROR Transfer event TRB DMA ptr not part of current TD ep_index 1 comp_code 1

During this time, video stutters and audio coming to the headphone stutters and repeats. It sometimes makes having meetings difficult.

This has happened since 4.18 on cosmic, and was just as bad on 5.0 disco. When I moved to 5.3 eoan things got better, but I still experience these problems.

Usually these problems make Firefox unusable too, but for this particular snapshot of logs, Firefox continued to work fine.

If I unplug the headset and move it from a USB 2 port to a USB 3 port I can usually get through the meeting okay.

[Test Case]

Use a Logitech H340 USB Headset with Google Meet on Firefox. This is not always reproducible, and I am still determining how to reliably reproduce.
