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.

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.
