I’ve recently bought a Home Assistant Yellow and want to add bluetooth capability. However, when following the guidelines, I always get a message saying there’s no bluetooth devices detected, despite having the bluetooth USB, a Sabrent one which I confirmed is on the compatible bluetooth USBs list plugged in. I tried both ports.
So, as it was not being detected, I went and followed the debugging instructions and logged into the home assistant using serial over USB.
The output from lsusb is as follows:
Bus 001 Device 001: ID 1d6b:0002
Bus 001 Device 002: ID 1a40:0101
And the output from dmesg | grep -i usb is as follows:

I also tried inserting a known good USB storage device, but again, no meaningful change in the output. I confirmed that both devices work fine when plugged in to other computers. I see no output anywhere which suggests the OS can see any USB devices other than the hubs. There are also no meaningful hardware errors that I can see in the full dmesg output. I’ve also tried rebooting on multiple occasions.
At this point I’m thinking I may have faulty hardware, but can anyone else think of any further troubleshooting steps?
