SD card reader dmesg, udev

[loux.thefuture]

Hello,
i have a big trouble with my 7-in-1 card Reader,
the hardware is recognised by sg, usb_storage as dmesg give me :
<-
scsi 0:0:0:2: Direct-Access OTi SD CARD Reader 2.00 PQ: 0 ANSI: 0 CCS
sd 0:0:0:2: Attached scsi removable disk sdc
sd 0:0:0:2: Attached scsi generic sg2 type 0
->
But when i plug a memory card inside the slot, nothing happens (not output on dmesg)
so i need to do : mount /dev/sdc /mnt/sdcard (which will not work i know but ...)
and then i got in dmesg :
<-
SCSI device sdc: 1984000 512-byte hdwr sectors (1016 MB)
sdc: Write Protect is off
sdc: Mode Sense: 03 00 00 00
sdc: assuming drive cache: write through
SCSI device sdc: 1984000 512-byte hdwr sectors (1016 MB)
sdc: Write Protect is off
sdc: Mode Sense: 03 00 00 00
sdc: assuming drive cache: write through
sdc: sdc1
SQUASHFS error: Can't find a SQUASHFS superblock on sdc
FAT: bogus number of reserved sectors
VFS: Can't find a valid FAT filesystem on dev sdc.
->
so now i can mount my /dev/sdc1

this is very strange when i plug my sd card for the first time i got nothing on dmesg/udev,

PS : kernel 2.6.19-gentoo-r5
sg/../usb_storage in kernel or in module do the same things !

udevinfo give me : udevinfo -a -p /block/sdc/sdc1
looking at device '/block/sdc/sdc1':
KERNEL=="sdc1"
SUBSYSTEM=="block"
DRIVER==""
ATTR{stat}==" 135 135 0 0"
ATTR{size}=="1983495"
ATTR{start}=="249"
ATTR{dev}=="8:33"

looking at parent device '/block/sdc':
KERNELS=="sdc"
SUBSYSTEMS=="block"
DRIVERS==""
ATTRS{stat}==" 16 139 282 32 0 0 0 0 0 32 32"
ATTRS{size}=="1984000"
ATTRS{removable}=="1"
ATTRS{range}=="16"
ATTRS{dev}=="8:32"

I get somewhat similar results, but the mount command yields nothing and I can't get the sd card recognized at all -- is this a udev problem?

[loux.thefuture]

i think it's a kernel/module trouble and not udev one,
i remember older kernel hadn't this trouble,
but nobody care don"t they ?
see you

I have discovered that things work much better if I set
CONFIG_SCSI_MULTI_LUN=y
This made the card reader work and it saw all the devices
in the reader which it had never seen before.

[loux.thefuture]

i have already set that CONFIG_SCSI_MULTI_LUN=y
and the kernel see my 7 in 1 card SD/MS/...
but not when i insert a card
