Gaming DSi won't read 8 GB or 16 GB microSD-card with adapter

[Namesnipe]

So, I've been attempting to brew my DSi XL, and when I put my sd card back in [in the flipnote studio data management step], it didn't read it. Then, I inserted the 16 GB microSD to test if it was a problem with my DSi's SD card slot, and they both gave me a ? and a message stating that "The device inserted in the sd card slot cannot be used." I later formatted it, and still nothing. Here's some extra information. They're both SDHC, in FAT32 format. I have not attempted putting it in with no files.
EDIT : I have attempted putting it in with no files and it still does not read it.

Swipe the lock key up or down on the adapter side, if it's on locked position, will not read at all.

They aren't locked.

Does it work in another software (system settings, camera, etc)?

Assuming it works in another device, bad slot/connection to motherboard/processor

Nope, I just gave up and assumed my card reader broke because it's my childhood DSi.

These adapters have a tendency to be unrelieable

MicroSD are shit for DSi, Use a full size as they are alot more reliable and work better with the DSi. did it for mine
