Speculative for https://forums.raspberrypi.com/viewtopic.php?t=371104 based on a past experience with "fast" USB3 UVC devices on "slow" processors, and running out of URBs resulting in dropped image data.

From the lsusb dump in the thread, these are apparently FS devices:

	Line 62:    Port 1: 0000.02a0 5Gbps power Rx.Detect
	Line 733:    Port 1: 0000.0303 lowspeed power enable connect
	Line 734:    Port 2: 0000.0103 power enable connect
	Line 799:    Port 1: 0000.02a0 5Gbps power Rx.Detect
	Line 940:    Port 1: 0000.0100 power
	Line 941:    Port 2: 0000.0103 power enable connect

Bus 3 device 3 could be either of the Port 2 connections.

I couldn't find that detail, hence the suggestion.
It sounds unlikely though, so I'll close this (CI will still complete).
