The SD adapter 2GB, 4GB and 8GB microSD / microSDHC read. Unfortunately, this is not the case with USB 2.0 card reader. This can only handle 2GB cards. Unfortunately, this is not in the product description and not on the packaging. After I first returned because my 4GB and 8GB cards are only read by the SD adapter, unfortunately I had to realize that even the new USB 2.0 card reader can not. Then I expanded my 2GB card from the phone. Here the USB 2.0 card reader worked.
