I've been fighting what may be this issue since I got my 2020 MacBook Pro.
I have a caldigit usb-c pro dock (which shows as thunderbolt 3 on my Mac), and my external USB2 (which show up as USB 2.1) mechanical keyboard and mouse (through a USB switch, which I've replaced) will suddenly stop responding and will not work again until I unplug the dock from the Mac and plug it back in. Disconnecting and reconnecting the USB devices themselves does nothing and system profiler shows them as still connected.
My Apple USB extended keyboard and logitech mouse (instead of the mechnical keyboard and logitech mouse) do not seem to exhibit this symptom.
I have not yet tried the mechanical keyboard connected directly to the dock w/o the USB switch(es); nor have a tried my little stand alone USB-C to USB-A adapter. Still narrowing down specifics.
