[Detector Support]: Hailo 8 driver not installed in HAOS, but should be

[emackinnon1]

Describe the problem you are having

I was directed here after opening an issue in the Frigate HA integration repo.

I am a novice with vision models, NVRs and Frigate; apologies for any dumb questions. Happy to post this somewhere else, but figured I'd start here. Until now, I had a coral TPU and then OpenVino using Intel's iGPU. Now I am wrestling with getting a Hailo 8 in an NVMe enclosure plugged into the thunderbolt port working with the default yolo model (and then hopefully yolov8 or v9). From what the logs say, it seems that the hailo driver is not installed. However, I was under the impression that due to the wonderful collaboration and efforts of the Home Assistant, Frigate and Hailo communities, HAOS now comes with the driver installed (referenced here on hailo's forums).

Main errors I notice in the logs are:

frigate.detectors.plugins.hailo8l ERROR : Inference error: [HailoRT] [error] Can't find hailort driver class. Can happen if the driver is not installed, if the kernel was updated or on some driver failure (then read driver dmesg log)
[HailoRT] [error] CHECK_SUCCESS failed with status=HAILO_DRIVER_NOT_INSTALLED(64)
frigate.detectors.plugins.hailo8l ERROR : [INIT] Failed to initialize HailoAsyncInference: libhailort failed with error: 64 (HAILO_DRIVER_NOT_INSTALLED)
Saw this similar issue but I haven't made much headway after surfing hailo forums and github issues so hoping someone here might be able to help.

Hardware info:
Running generic x86-64 bare metal HAOS on a GEEKOM Mini PC with 13th Intel Core i7, 32GB DDR4 RAM and 1TB PCIe Gen4 SSD and with plenty of thunderbolt ports. Hailo 8 is in an ORICO M234C3-U4 enclosure. I haven't eliminated the enclosure or something physical as the problem as the hailo does not show up after running lspci and I believe it should do so (but enclosure/chip lights up when plugged in). Running dmesg shows nothing.

Unfortunately trying to set Hailo 8 as the detector causes Frigate to fail, so here is camera tab with Intel iGPU and OpenVino running as detector.

I am not sure which one the General tab is, but didn't see it in the Home Assistant add on.

Any other information that may be helpful

Thank you in advance for any help.

The core issue here is that your Hailo 8 device is not being detected at the hardware level—lspci shows nothing and dmesg is empty. This indicates the problem is occurring before Frigate or the Hailo driver can even interact with the device.

The Thunderbolt/USB-C enclosure is likely the issue. The Hailo-8 and Hailo-8L modules are designed to connect via PCIe (either M.2 or through a PCIe carrier board). (1) Connecting through a Thunderbolt-to-NVMe enclosure introduces additional complexity:

1. The enclosure must properly expose the PCIe device to the host
2. Thunderbolt devices often require explicit authorization in Linux
3. Not all NVMe enclosures properly pass through non-storage PCIe devices

Troubleshooting steps:

1. Check if Thunderbolt is recognizing the enclosure at all:

cat /sys/bus/thunderbolt/devices/*/device_name

2. Look for any Thunderbolt authorization issues:

cat /sys/bus/thunderbolt/devices/*/authorized

3. If the device shows but isn't authorized, you may need to authorize it manually or configure Thunderbolt security settings in your BIOS.

Regarding HAOS and Hailo drivers: The Hailo driver is included in Home Assistant OS, but the driver can only work if the hardware is visible to the system at the PCIe level. (2) Since lspci shows nothing, the driver has nothing to bind to.

Recommendation: Before troubleshooting software/drivers further, confirm the Hailo device appears in lspci. If it doesn't, the enclosure may not be compatible with passing through the Hailo as a PCIe device, or there may be a Thunderbolt authorization issue. You might need to test with a direct M.2-to-PCIe adapter in an internal slot rather than an external Thunderbolt enclosure.

@inkeep is there another way to show the authorized thunderbolt ports or enclosures? The

cat /sys/bus/thunderbolt/devices/*/device_name

command is not the right approach. I have tried dmesg and lspci to find the enclosure, but it does not show up.

[inkeep-ai-assistant[bot]]

I don't have specific information in my sources about Thunderbolt device enumeration commands—this falls outside of Frigate's documentation scope.

However, since the device isn't appearing in lspci or dmesg, this is a hardware/OS-level issue that needs to be resolved before Frigate can detect the Hailo. Some general approaches to investigate Thunderbolt devices on Linux include:

• boltctl list - if bolt is installed, this shows Thunderbolt devices and their authorization status
• ls /sys/bus/thunderbolt/devices/ - to see if any Thunderbolt devices are enumerated at all
• Check BIOS/UEFI settings for Thunderbolt security mode (some systems default to "No Security" while others require explicit authorization)

Since the enclosure lights up but nothing appears in system logs, the issue is likely either:

1. The Thunderbolt controller isn't recognizing the enclosure as a valid device
2. The NVMe enclosure doesn't properly pass through non-storage PCIe devices (many are designed specifically for SSDs)

For Thunderbolt-specific troubleshooting beyond Frigate, you may want to check the Home Assistant community forums or Linux Thunderbolt documentation.

Check out these potentially useful sources: [Detector Support]: I have DKMS built and I can see /dev/apex_0 but Frigate cannot see the TPU

Would you like me to try to provide a general answer about Thunderbolt device detection on Linux?
