Ok I rebuild the kernel and use atausb instead of umass.

Here is the dmesg output, so it is not working either.

atausb0: <USB Mass Storage, class 0/0, rev 2.00/2.00, addr 2> on usb2

If I use umass,

umass0: <USB Mass Storage, class 0/0, rev 2.00/2.00, addr 2> on usb2
umass0:  SCSI over Bulk-Only; quirks = 0x0000
umass0:0:0:-1: Attached to scbus0

cd0 at umass-sim0 bus 0 target 0 lun 1
cd0: <NATIONAL FLASH DISK 2.00> Removable CD-ROM SCSI-2 device

cd0: cd present [30720 x 2048 byte records]
GEOM_LABEL: Label for provider da0s1 is msdosfs/NATIONAL.
GEOM_LABEL: Label for provider cd0 is iso9660/NATIONAL.

[mcuee at freebsd7 /usr/home/mcuee]$ sudo mount_cd9660 /dev/cd0 /media/usbcd/
mount_cd9660: /dev/cd0: Invalid argument

Something is strange here.
