I’ve been trying to connect the CC2531 dongle to Home Assistant. The USB device is detected. But when I start the addon, it won’t be able to connect to it. Here are the logs:

I’ve tried /sys/devices/pci0000:00/0000:00:06.0/usb2/2-2 and /devices/pci0000:00/0000:00:06.0/usb2/2-2 
without much luck. Am I missing something? Or do I have to do an extra step to the dongle? I just received it and plugged it in.
