You need to set baudrate to 460800 & enable rtscts according to the Z2M docs for the zbt2.
I already tried that, but I'll try again when I get home; I'm at work now. Besides that, do you have any other suggestions I might have? I'm following all the instructions; I honestly don't know what else to try. Thanks for your help.
Do that first & see if it works or if the USB discovery error changes.
Hello again, I've found the solution, and I'm posting it here in case anyone else has the same problem.
After following the steps on the official website and manually entering the device address parameters, such as the adapter, baud rate, and enabling RTSCs,
I managed to fix the registry errors and get the network working by deleting a file called "coordinador_backup.json" with a file editor. It's located in the zigbee2mqtt folder. Once deleted, go to plugins/Zigbee2MQTT and click "Start Network," and the new network will be created.
In my case, I then added all the devices so the network would detect them quickly; some of them did it automatically.
This is what worked for me after many failed attempts, but it won't work for everyone, so be careful.
Thanks to those who have helped me.
