WSL2 is backed by an actual virtual machine, so it comes with the limitations of its hypervisor (Hyper-V). Hyper-V doesn't support full USB passthrough. AFAIK it does support passing down USB volumes though.
You can mount partitions/drives but something like a yubikey, mic, etc you can't right now
Ah, ok. I was trying to follow a support thread and it wasn't clear about that. It made it sound like WSL2 didn't support USB at all.
