[Support]: 1 out of 4 Edge TPUs not detected
Describe the problem you are having
I have 2 Dual Edge TPUs installed in MBS's PCIE adapters. I'm running Frigate as a Hassio addon for Home Assistant.
Frigate consistently reports for pci:2 "No EdgeTPU was detected. If you do not have a Coral device yet, you must configure CPU detectors."
This occurs at pci:2 even when the 2 dual TPUs & adapters are swapped, so I'm not convinced it's a hardware issue.
Linux shows all 4 apex devices:
dmesg | grep apex
[ 11.051976] apex 0000:04:00.0: Apex performance not throttled due to temperature
[ 11.051984] apex 0000:03:00.0: Apex performance not throttled due to temperature
[ 11.306691] apex 0000:08:00.0: Apex performance not throttled due to temperature
[ 11.310702] apex 0000:09:00.0: Apex performance not throttled due to temperature
ls /sys/class/apex/
apex_0 apex_1 apex_2 apex_3
I suspect it might be a permissions issue, but the permissions on the devices are all identical:
ls -l /dev/apex*
crw-rw---- 1 root apex 120, 0 Jul 26 16:17 /dev/apex_0
crw-rw---- 1 root apex 120, 1 Jul 26 16:17 /dev/apex_1
crw-rw---- 1 root apex 120, 2 Jul 26 16:17 /dev/apex_2
crw-rw---- 1 root apex 120, 3 Jul 26 16:17 /dev/apex_3

You need to use the beta addon to support 4 corals, currently stable only supports 3
That might not matter for the full access addon. Is it always the same one that fails? Does it work if you only configure the 3 that work?
Yes, it works if I comment out the Coral3 block (the one that fails)
I'll try tomorrow commenting out the coral4 block and seeing if it still works in that configuration.
Commenting out Coral4 but leaving Coral3 fails:

Also interesting that it's pci:2 which I imagine maps to apex_2, figure it would be apex_3 that wasn't found if it was related to https://github.com/blakeblackshear/frigate-hass-addons/pull/72
