Developer ischeinkman has been working on basic file transfer to & from the Switch via USB C cable. It’s still a WIP as it can be very slow to transfer file and sometimes it can screw up the transfer.
To use NXUSB download the nxusb_server.nro and put it on your micro SD card like any other homebrew you use.
Run nxusb_server.nro on the switch and connect it to the PC via USB C. Then use a client to transfer files to the PC or Switch via cargo build -p client and the –push and –pull command.
“At the moment, the client executable is called simply client, so it’s what will be used, although this may change in the future.”
