 "title": "Luckfox Pico Zero over USB: the 2207:0019 'rk3xxx' gadget is RNDIS+ADB with no DHCP on either end - give the host 172.32.0.100 with nmcli, no sudo needed",
 "symptom": "lsusb shows 'Fuzhou Rockchip Electronics rk3xxx' 2207:0019 and a new enx... interface (driver rndis_host) appears, but NetworkManager sits in 'connecting (getting IP configuration)' indefinitely, the interface never gets an IPv4 address, and ping 172.32.0.93 fails. The board does not answer IPv6 link-local either (ping ff02::1 on the link returns only the host itself).",
