USB Audio drivers load inconsistently depending on whether I am booting or rebooting

This may sound a bit crazy, but I'm not even sure if this bug is worth reporting. It could be happening only on my system: Dell XPS laptop 9710 (has 4 USB-C ports) with Ubuntu 20.04. $ uname -r reports 5.11.0-37-generic

After a lot of study, I have noticed 3 different behaviors with respect to starting up

1. When I power on my machine from a cold off state with devices unattached

My external keyboard and mouse almost always work fine. My monitors occasionally do not start correctly. Sometimes I get a black undetected monitor, other times it starts but in very low resolution mode, like Ubuntu forgot what display resolutions are available, or the order and arrangement are reset USB Headphones are not detected, even after waiting a long time. They literally do not show up in lsusb

2. When I power on my machine and have devices connected via USB-C hubs

I have tried at least 5 or 6 different manufacturers of USB-C multi-function hubs. Booting occasionally will hang at the black screen if certain devices are connected requiring a force power down, unplug USB devices comlpetely, wait for 10 seconds and retry booting My monitors occasionally do not start correctly. Sometimes I get a black undetected monitor, other times it starts but in very low resolution mode, like Ubuntu forgot what display resolutions are available, or the order and arrangement are reset USB Headphones are not detected, even after waiting a long time. They literally do not show up in lsusb, same output as above

3. When I startup normally with no devices plugged in, login, plug in devices, then reboot

This has proven to work the best for me. In this case, the USB Audio drivers are loaded fine, every time, usually monitor settings are preseved as well

If you noticed, the "reboot" option properly shows Plantronics as one of the devices. Those are my USB headphones.

Why would cold power on be different from reboot, with respect to loading USB-connected drivers?
