Hi,

Most likely The firmware on your pendrive is not fully SCSI compliant.

Read: http://wiki.freebsd.org/USB

and the section about adding an USB Mass Storage Quirk.

You need to add something like this to "sys/dev/usb2/storage/umass2.c" :

        {USB_VENDOR_MEIZU, USB_PRODUCT_MEIZU_M6_SL, RID_WILDCARD,
                UMASS_PROTO_SCSI | UMASS_PROTO_BBB,
                NO_INQUIRY | NO_SYNCHRONIZE_CACHE
        },

--HPS
