How can I get more detail on what USB device is constantly disconnecting?

Just noticed a notification (and I don't have the grab of it or wrote down the message before I clicked-to-launch) about a USB device constantly disconnecting and that this would cause problems with BTT.

How can I find out which device? I don't have many and I wish I'd written the time down but I've been away most of the day. I have a bluetooth keyboard but I don't know if it's a catchall description.

I'm not sure if this is the best way, but I would use the System Information app (built in).

Select USB for USB information and keep refreshing it with ⌘R

Should have mentioned but now obvious, my machine was asleep before I saw the notifications. It wasn't flickering, just happened to scan through them.
