ZHA - Nortek HUSBZB-1 error - Inappropriate ioctl for device

I’m getting the above error when trying to add the zha integration via configuration.yaml:

          usb_path: /dev/NortekHUSBZB-1
          database_path: /home/me/.homeassistant/zigbee.db

where /dev/NortekHUSBZB-1 is a symlink to the Nortek HUSBZB-1 device created by a udev rule, although I get the same error when I reference the direct path (/dev/bus/usb/001/007) in configuration.yaml.

I’m also not sure if I’m linking to the right device. The manual says it should appear as two devices, but I’m not sure how to access each individually.

dmesg | grep USB:
[292801.415493] usb 1-10: new full-speed USB device number 7 using xhci_hcd

ls /dev/bus/usb/001/
001  007

Looks like it’s getting found, but I only see one device but it doesn’t seem to work with the zha or with Z-Wave integrations. What am I missing?

I contacted Nortek support about this and they told me the HUSBZB-1 requires a firmware update that is no longer available due it not being sold or supported in the last five years. I sent it back and replaced with a Conbee II on an extension cable and a Aeotec Z-Stick and both of them showed up as serial devices (/dev/ttyACM0, /dev/ttyACM1–unlike the HUSBZB-1 which only showed up as a USB device like above.) and the integrations work better now.
