Byte 7 of register CSD v2.00 is so composed: the first 2 bits for "reserved3" and the remaining 6 bits for "c_size_high". Because of how the bits are arranged on little-endian systems, "c_size_high" must be positioned before "reserved3" in order to have "c_size_high", "c_size_mid" and "c_size_low" arraged contiguously.
Type of csd.v2.c_size_mid is uint8_t (8 bits). In order to left shift by 8 bits csd.v2.c_size_mid without losing informations (bits), is necessary to cast the variable to uint32_t.

Fix position of "c_size_high" in struct "csd2_t" and cast 8 bits variable ("csd.v2.c_size_mid") to allow left shift by 8 in cardSize() method.
