I just received today my Steam Deck Oled! It’s my first Deck and so far really happy with it.

I’ve been tinkering with desktop mode and installed EmuDeck, so easy to configure it.

I want to use the tool it comes with to copy ROMs from a USB drive to the Deck but I can’t manage to get the USB drive to mount or even appear in the OS. I’ve tried formatting it in NTFS, exFAT and Fat and none of them works. I’ve also tried connecting a USB mouse and it isn’t working (don’t know if this is relevant) Am I doing something wrong? I’m sure it’s something very basic but I just can’t figure it out.

Thanks in advance!
