I have OPi 5 plus, not the 5B, but I'm not running into the issue you're describing, the Coral shows up fine.
I can think of two possible issues, though:
- Did you already know that the Google Coral doesn't show up under a sensible USB device ID until you perform an inference for the first time ( https://github.com/google-coral/edgetpu/issues/536 ) ? It presents as USB device ID "1a6e:089a Global Unichip Corp." until you touch it, and then transforms into "18d1:9302 Google Inc."
- The Google Coral takes a ton of power over USB, especially if you're using libedgetpu1-max instead of libedgetpu1-std. Maybe your 5V supply isn't beefy enough?
