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

Yep. It was there, but blank.

It was giving me real problems because the current version of OpenMenu will not boot if there is no VMU... and with the blank file, my VMU wasn't working.

Hello!

I was able to create the USB4Maple adapter, and when I connect a USB controller directly, it works correctly. However, I can't get it to work if I use a USB hub.

I've tested all the USB hubs I have—about six of them—some are USB-C hubs, others using a USB-C to regular USB adapter, and in none of them did I manage to get the controller working, nor the USB storage for the VMUs, nor the OLED display.

Any ideas on what it could be?

Regards.

Hello again!

Using an usb splitter it worked fine, but now I have a problem with the oled screen, it works but it's rotated 180º

There is any possibility to add a config file to the usb storage, to make some fixed adjustments?
It would be awesome if we can remap using a cfg file some gamepad buttons, like r1 to l1, and also rotate the oled screen display 180º because of solder position I can't rotate it physically)

Interesting I had a similar situation with 4x4 evolution. Only one game had a flipped OLED screen!

Anyone have a 3d print with OLED screen available. Was wanting to build more.

In my case, it's rotated for all games I tested

I added an internal usb4maple, usb storage and Bluetooth dongle, and for the screen a detachable oled display, that covers the unused port (because of bt dongle)

This is why I was asking a config way to rotate the oled display.

@Quiquonn Can you provide a link to the screens your using?
