You can check the device name to which they are attached by checking the
dmesg or /var/log/messages. This is from attaching a card reader with
multiple slots, but only one of them holding a card (sd4):
$ dmesg
...
umass0 at uhub0 port 12 configuration 1 interface 0 "Generic USB Storage"
rev 2.10/12.09 addr 9
umass0: using SCSI over Bulk-Only
scsibus5 at umass0: 2 targets, initiator 0
sd2 at scsibus5 targ 1 lun 0: <Generic, MassStorageClass, 1209> removable
sd3 at scsibus5 targ 1 lun 1: <Generic, MassStorageClass, 1209> removable
sd4 at scsibus5 targ 1 lun 2: <Generic, MassStorageClass, 1209> removable
sd4: 30608MB, 512 bytes/sector, 62685184 sectors
sd5 at scsibus5 targ 1 lun 3: <Generic, MassStorageClass, 1209> removable
If in doubt, you can then check which partitions that disk holds using
disklabel:
$ disklabel sd4
...
# size offset fstype [fsize bsize cpg]
c: 62685184 0 unused
i: 62676992 8192 MSDOS
In this case, a single MSDOS partition (i) that you can then mount:
# mount /dev/sd4i /mnt
