Making USB drives work for Profiles

Hey, I've looked everywhere but I can't find a way to make this work. I've been trying to get USB Flash Drives working on StepMania 5.0.9 (I recently switched to this version because the one I was using was obsolete) on my theme, I've plugged in my USB several times but I still don't see an option to create a profile through USB Flash Drives. What do I do?

Extra-Info: What I'm trying to achieve is a system similar to Pump it Up Infinity's one, which is basically a copy from Save/LocalProfiles/[PROFILENAME] files. After plugging in a USB on the title screen, the game detects it and, after playing a session, the profile is created automatically on the USB. I believe I can make that work, but I need to know how to make the normal USB system work first.

EDIT: A solution has been found. Saving for future reference.

I'm just gonna bump this and say that this has been already answered.

Really? Almost a year and not a single answer?

Yeah I came across that thread recently, but it wasn't there when this thread was created. However you're the only one that offered any kind of help. Thank you!
