Unhappy USB Camera Mandy 9.2 and lack of SCSI support - help?


I have just acquired a Digital Dream Enigma1 USB camera, and have spent the last 2 hours Googling and Searching How-Tos and LinuxQuestions. From what I can gather I need to mount the camera as follows:

mount -t vfat /dev/sda1 /mnt/camera

I had already created the camera directory under /mnt with

mkdir -m 777 camera

but on checking the /dev directory there is no sda1

lsmod | grep usb

gives the following:

usb-storage 91616 0 (unused)
scsi_mod 106176 4 (autoclean) [usb-storage sg st sr_mod sd_mod]
usb-uhci 25136 0 (unused)
usbcore 74988 1 [usb-storage usb-uhci]

lsmod | grep scsi

gives:

scsi_mod 106176 4 (autoclean) [usb-storage sg st sr_mod sd_mod]

/proc/bus/usb/devices has the following in it:

T: Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=12 MxCh= 2
B: Alloc= 0/900 us ( 0%), #Int= 0, #Iso= 0
D: Ver= 1.00 Cls=09(hub ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1
P: Vendor=0000 ProdID=0000 Rev= 0.00
S: Product=USB UHCI Root Hub
S: SerialNumber=fcc0
C:* #Ifs= 1 Cfg#= 1 Atr=40 MxPwr= 0mA
I: If#= 0 Alt= 0 #EPs= 1 Cls=09(hub ) Sub=00 Prot=00 Driver=hub
E: Ad=81(I) Atr=03(Int.) MxPS= 8 Ivl=255ms
T: Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 4 Spd=12 MxCh= 0

P: Vendor=2770 ProdID=913c Rev= 1.00
S: Product=USB DIGITAL STILL CAMERA
C:* #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=500mA
I: If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=ff Driver=(none)
E: Ad=81(I) Atr=02(Bulk) MxPS= 64 Ivl=0ms
E: Ad=02(O) Atr=02(Bulk) MxPS= 64 Ivl=0ms
E: Ad=83(I) Atr=03(Int.) MxPS= 1 Ivl=3ms

I am a bit stuck, I think that the standard Mandy kernel that I have installed doesn't have SCSI support loaded, but I don't know how to do this.

Please help.

create sda device in /dev directory

cd /dev
./MAKEDEV sda



or do you use devfs or something like this?

The command

makedev /dev/sda

took 1.5 hours at 99% CPU usage and created approx 8000 entries under the sda directory, one of which was an sda1 which when added to the mount

mount -t vfat /dev/sda/sda1 /mnt/camera

returned

/dev/sda/sda1 not a valid block device

I'm still confused?

Plug in the camera and look at the output of dmesg for messages relating to a mass storage device and sda.

The last few lines of dmesg:

Though the time stamp of this file is when it was booted up the file /var/log/messages contains the following and is written to when the camera is plugged in:
