I see there are several quirk entries for Sony cameras. Could you try to 
change "UMASS_PROTO_RBC | UMASS_PROTO_CBI" into "UMASS_PROTO_DEFAULT" for all 
DSC entries?

        {USB_VENDOR_SONY, USB_PRODUCT_SONY_DSC, 0x0600,
                UMASS_PROTO_RBC | UMASS_PROTO_CBI,
                RBC_PAD_TO_12
        },
