Not long after writing this I stumbled on this page people.canonical.com/~kernel/info/.... It maps ubuntu kernel versions to actual kernel versions. It turns out the kernel version I was using was 5.4.41! See this image, the ubuntu kernel version was 5.4.0-37.

Ubuntu kernel version map for ubuntu 20.04

I reverted to this kernel and all is well! So this was likely caused by an issue in the bad USB port, which means it is possibly another driver at fault. I might investigate this if I have time, it's interesting.
