32GB Micro SDHC is not recobnized by Samsung Galaxy Tab2

I just bought a 32GB Micro SDHC UHS Speed Class 1-Class 10 and inserted to Samsung Galaxy Tab2 10.1 but it could not been detected.
When I checked to setting - storage, its just said “insert sd card”.
What should I do?

Is it inserted al the way? My 1st guess based on your error msg. is that it is not.

I think I have inserted all the way.

There is only one way to insert (gold face down) & I have pushed it until a soft “click sound” heard and when I tried to plug off, I need to push it again until its slightly bounced.

I have the same issue for my TF700T. (Asus Transformer Infinity)

I have the Sandisk Ultra Mobile UHS-1 card and checking the dmesg log in the tablet (using a terminal client) shows it is getting read errors trying to read the FAT.

It sais it is trying to use DDR mode which must mean DDR-50 as that is the only mode supporting DDR.
