Coral TPU not detected by HA blue for Frigate

[fspatt (Frank Spatt)]

I’m having a similar problem. I am running HA on an old MacPro and VirtualBox. The device is seen by VB however when I include the detector in Frigate, it says it’s not there.

Removing the pass thru on VBox doesn’t work either.

[fspatt (Frank Spatt)]

Thought I had this working. Found that I had to load the VBox Extension Pack to get USB 3.0 loaded. Doesn’t seem to matter though.

If I delete the USB device Filters, no difference.
If I disable protection mode, no difference

Help!

I’m running HA on a HA blue. In order for Frigate addon to recognize my Coral USB I had to:

1. Uninstall “Frigate” addon and replace it with “Frigate (Full Access)” addon.
2. Unselect “Protection mode” on the Frigate (Full Access) addon page configuration->addons->Frigate (Full Access)

(I do not have any power issues. I’m running Coral on the top left USB and a Z-Wave controller on the bottom right.)

Also, remember that Frigate (Full Access) addon uses a different URL than the standard addon. The integration must probably be reinstalled in order to change the URL to http://ccab4aaf-frigate-fa:5000

[fspatt (Frank Spatt)]

Thank you. I’m also running Full Access. My system is now working correctly. Seems the MacPro was cycling the USB port for some reason.

[Tanjohnson99]

I alsao have the same issu, the Google coral is not reconized in Hardware…

[luisrival]

The same problem, I´m running in Hass OS in a intel NUC, and it doesn´t recognize my USB Coral, I try in the 3 usb ports and nothing Any idea? Also I try using an usb powered hub and nothing

If you have problem with

Coral USB and Frigate Full Access turn off security mode
frigate.edgetpu INFO : TPU found

[csader (Chris)]

Hate to revive an old thread, but I’m having the same issue. I have a powered USB hub, have tried all ports on the HA Blue, and still get “No EdgeTPU was detected”. Tried rebooting, tried disabling protection mode in Frigate (Full Access), no luck.

Any more ideas?

[Ranzor (Jörgen)]

I have the same problem, how did you get it working?

[dharvey24 (David)]

I had the same problem and fixed it by replacing the USB cable that came with the Coral. Now tried in both the RPI and my separate Frigate Server both can see the Coral without a USB powered hub or anything.

[CrocMonster (Johan)]

Jup, that’s IT

edit: Oh! and both my HaBlue’s 5v usb 4 ports are broke, so it works with the micro-usb OTG on the front with 4 port usb passive hub with conbeeII, aeotec z-wave and han/P1.

[derekngibbs]

I’m having the same issue with NUC, HAOS, and Frigate. I have Frigate FA and protected mode off. Frigate is still complaining about not seeing the TPU. Is there a LED on the Coral? Also, what fixed your problem?

[CrocMonster (Johan)]

Welcome!
It’s been a while…hard to remember
Yes the Coral has a led, blinking when working.
Add-on : Frigate(Full Access), protection mode - off
Edit: Mine is connected to a passive external 4port usb hub (in front) due to the HA Blue Odroid N2+ SBC 5V power to usb 4port usbs (in back) breaks by power spikes or switching your houses fuses off and on. Happened to both my HA Blues
