ZBT-1 not recognized after restoring from backup

Configuration Zigbee
1

Hi,
I just had to reinstall my HA OS after the SD card died. I’m running on a Raspberry Pi 400, I installed the latest HA OS, and restored from backup after initial installation. So far so good.
The ZBT-1 is connected to the RP400, but it’s not showing up anywhere. I also didn’t find it under Settings->Hardware.

Plugging it into my desktop I get the following from dmesg:

[ 4905.940980] usb 1-1.1: new full-speed USB device number 7 using xhci_hcd
[ 4906.063765] usb 1-1.1: New USB device found, idVendor=10c4, idProduct=ea60, bcdDevice= 1.00
[ 4906.063775] usb 1-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[ 4906.063780] usb 1-1.1: Product: Home Assistant Connect ZBT-1
[ 4906.063784] usb 1-1.1: Manufacturer: Nabu Casa
[ 4906.063786] usb 1-1.1: SerialNumber: 2886367beacaed11955dc171cda106c3
[ 4906.066192] cp210x 1-1.1:1.0: cp210x converter detected
[ 4906.076338] usb 1-1.1: cp210x converter now attached to ttyUSB0

It also showed up with lsusb:

Bus 001 Device 007: ID 10c4:ea60 Silicon Labs CP210x UART Bridge

So I think the dongle itself is working. But this was on my laptop, not on the Raspi running HAOS.

I tried to enable host SSH access using the CONFIG usb drive method, but that just didn’t work. So unfortunately I can’t see what dmesg or lsusb say there.

I’ve rebooted multiple times, but so far the ZBT-1 integration just isn’t showing up. ZHA is sad with “Failed setup, will retry”, and is basically stuck there. It still shows all my Zigbee devices, but offline, of course.

Any idea what I can do to fix this, or at least debug more?

OS release 17.2 had an issue with the Pi4 not recognising usb devices. Not sure if this issue also extends to the Pi400, but the fix for this is to update the eeprom in the Pi.

Thank you, that did the trick!

I didn’t realize that the entire USB subsytem didn’t work. That also explains why I wasn’t able to setup the host ssh access using the USB drive. Both the ZBT-1 as well as ssh work now :slight_smile: thank you!
