Much easier.
Get a cable. plug it into both machines. Configure the RuiDa with 10.10.1.100, 255.255.255.0
Configure the PC ethernet with 10.10.1.1, 255…255.255.0 - no gateway needed on the PC - it already got that from the WiFi and has set up the routing tables for you.
Go to cmd, type ‘ping 10.10.1.100’ and see if you get a return.
Never use USB again
