Problem Description:
I purchased a transcend usb multicard reader, the question is that when I
configured the device, the system only found one of the three slots (Yes!! I
enable the option 'probe all LUNS in each scsi device' in the kernel).
To get the problem solved, I edited the usb-storage driver (usb.c), and changed:

case US_SC_8020:
                        ss->protocol_name = "8020i";
                        ss->proto_handler = usb_stor_ATAPI_command;
                        ss->max_lun = 0;
                        break;
                                                                               
                                              
for  
 case US_SC_8020:
                        ss->protocol_name = "8020i";
                        ss->proto_handler = usb_stor_ATAPI_command;
                        ss->max_lun = 2;
                        break;
                                                                               
                                              
when i change the zero for the two and recompile, it works.
I don't know why the number by default of max_lun is zero. Because of this i
report this fact.
