The Coral TPU driver has basically been abandoned by Google so if you are running a Linux kernel newer than 6.2 it will not function.
https://github.com/google/gasket-driver is the original driver which was archived on April 18, 2026
You can try the driver https://github.com/feranick/gasket-driver or https://github.com/dude84/gasket-driver-coral or search through the forks of the original gasket-dkms driver https://github.com/google/gasket-driver/forks
So in the future your options are to pin your kernel to 6.2, upgrade your hardware, hope that someone will keep a gasket-dkms fork updated for newer kernel versions, or make your own fork to do so yourself.
It’s due to the inner workings of the Coral TPU being basically a black box, so even if the community wanted to, we can’t just reverse engineer a driver.
