I am USB printing because i have bought a new memory card due to the last one getting corrupted but when i put it in the slot it just slides in and doesn't read so i would give it a weak little pull to make sure its in and it just slides out and it doesn't detect it as connected. (i have tried making sure the card is valid and it is the right size i have a reader on my computer)
Edit: I checked when I plug it in it does in fact click
