An USB card reader usually shows up as a SCSI mass storage device.
In that case device entries are created under /dev/scsi/, and some
corresponding entries under /dev/discs/ as well. You can check which
devices where created by looking at the ouput of dmesg, or check the
kern.log or sys.log files in /var/log/.

Don't know of a way to get /dev/usb/cm* entries with devfs.
