nokia 3300 MMC usb-storage

[Chineseyes]

I have a nokia 3300 cell phone with a 64MB MMC usb-storage recognizes the card but when I try to mount the drive I get

localhost lun0 # mount /dev/sg0 /mnt/nokia/
mount: /dev/sg0 is not a block device

vfat msdos and the rest of the drivers are loaded I just can't mount the drive
