1 year ago I am also having this issue with my mini PCI-E Coral. The device is listed as "Global Unichip Corp. Coral Edge TPU" as expected, however /dev/apex_0 does not exist. Platform is a HP DL360p server.

Hello all,
I have installed DEBIAN "bookworm" in the latest version: 5.18.0-3-amd64 #1 SMP PREEMPT_DYNAMIC Debian 5.18.14-1 (2022-07-23) x86_64 GNU/Linux on my computer.
Until recently I was able to use the M2.Coral card, but now (after kernel update) the system can no longer find this card and I can no longer activate it.
What can I do or is there already a remedy for this? Best regards Z. Matthias
