Transfers data to/from USB MSC endpoints.

Parameters
b_readMemory to USB, if true
blockBuffer on Internal RAM to send or fill
block_sizeBuffer size to send or fill
callbackFunction to call at the end of transfer. If NULL then the routine exit when transfer is finish.
Returns
1 if function was successfully done, otherwise 0.
