USB4MAPLE adapter

I just discovered a new bug with the VMU2.

On your flash drive, there is a file called "last.cfg". This file keeps a memory of the last memory card you opened.

If however, this "last.cfg" file is empty, and you boot into an OS without VMU2 support, then whatever software you are running will never register with VMU support. Basically, memory card support is dead. The solution for me was to simply plug the flash drive into my PC and add "openmenu.bin" to the file, and everything started working again.

when installing a clean flash drive, a vmu.bin file is created on it, if it is not created, then your flash drive has compatibility issues with the rp2040.
unfortunately, the rp2040 has compatibility issues with some USB devices

It wasn't a new card. It was the card I've been using for the past few weeks. For some reason, the last.cfg file was empty, and because of that, the VMU wouldn't work... until I edited the file.

that is, the last.cfg file itself was present, but it was empty?
in this case, I will add a check for the length of the line to avoid such problems. most likely, at the moment of saving last.cfg, the console or usb4maple was disabled, so the file did not have time to be written
