hello, how are you?, I tell you, a long time ago I bought a badusb cjmcu, basically it is an atmega 32u4 with an SD reader, it worked fine for me for a long time, I used it in cybersecurity exhibitions, but from one moment to another (after a while I didn't use it) the SD area doesn't work, I tried several of the codes that exist for this or similar ones and the reader it comes with doesn't work.
I don't know if it could be dirt or the SD died due to static, upload the code and it works perfect but only the SD reader doesn't work
