Which scsi /dev do you use to mount a usb mmc reader/writer to?

Here is my lsmod:

usb-storage            25712   0  (unused)
uhci                   25616   0  (unused)
usbcore                62016   1  [usb-storage uhci]

When I plug in the device, with or without the MMC card in it, dmesg reports:
USB Mass Storage support registered.
hub.c: new USB device 00:10.0-1, assigned address 2
scsi1 : SCSI emulation for USB Mass Storage devices
Vendor: Generic Model: USB SD Reader Rev: 2.00
Type: Direct-Access ANSI SCSI revision: 02
WARNING: USB Mass Storage data integrity not assured
USB Mass Storage device found at 2


Now I try
mount  -t vfat /dev/sda /mmc
mount: /dev/sda is not a valid block device
same with sda1, sda2, etc

Now, one thing I do notice is there is no /dev/sda0, is that correct? I am no expert on scsi. What I have is:
/dev/sda /dev/sda11 /dev/sda14 /dev/sda3 /dev/sda6 /dev/sda9
/dev/sda1 /dev/sda12 /dev/sda15 /dev/sda4 /dev/sda7
/dev/sda10 /dev/sda13 /dev/sda2 /dev/sda5 /dev/sda8


And a scnabus:

I tried usb-uhci and it didn't even recognize the device.

Oh yea, /proc/bus/usb/devices has:

T:  Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#=  3 Spd=12  MxCh= 0

E:  Ad=01(O) Atr=02(Bulk) MxPS=  64 Ivl=0ms
E:  Ad=82(I) Atr=02(Bulk) MxPS=  64 Ivl=0ms

Also, I have SCSI_MULTI_LUN enabled in the kernel.
