Same problem for me: I upgraded my NanoPC T4 and spent a lot of time to configure everything. At the end I noticed USB-C is not working to connect my essential backup drive. I spent many hours for nothing, because I thought a "stable" release means that at least basic I/O functionality was tested. I understand that testing takes manpower and money. But if it is missing the releases should me called "stable" for a referenced device. I do not know how many other users run into the same problem and waste their time.
