So class 08 is just "mass storage". According to http://www.usb.org/developers/devclass_docs/usb_msc_overview_1.2.pdf, subclass 06 is "SCSI transparent command set" (very helpful :-( ) and protocol 50 is "Bulk-only transport". So nothing specific for card readers here, I'm afraid. My USB stick is exactly the same.
