Hi there,

I have several devies with various sorts of memorycards, and want to be able
to read and write to those cards from my Gentoo.

I got a 52-in-one USB 2.0 card reader (NQ-8602) from NorthQ, and started
reading the WIKIs;

http://gentoo-wiki.com/HOWTO_Multicard_reader
http://gentoo-wiki.com/HOWTO_USB_Mass_Storage_Device

The first really gives little help, when I don't know how the various cards,
gets recognised. So I read the second WIKI, and seems to be able to contact
the reader;

ls -l /dev/disk/by-id/usb*
lrwxrwxrwx 1 root root 9 Feb 7
2007 /dev/disk/by-id/usb-Generic_USB_CF_Reader_058F312D81B -> ../../sdb
lrwxrwxrwx 1 root root 9 Feb 7
2007 /dev/disk/by-id/usb-Generic_USB_MS_Reader_058F312D81B -> ../../sdd
lrwxrwxrwx 1 root root 9 Feb 7
2007 /dev/disk/by-id/usb-Generic_USB_SD_Reader_058F312D81B -> ../../sda
lrwxrwxrwx 1 root root 9 Feb 7
2007 /dev/disk/by-id/usb-Generic_USB_SM_Reader_058F312D81B -> ../../sdc

But

cat /proc/partitions

only returns the partitions on my 2 physical HDs.

I also get;

sg_scan -i && sg_map
/dev/sg0: scsi0 channel=0 id=0 lun=0 [em]
Generic USB SD Reader 1.00 [rmb=1 cmdq=0 pqual=0 pdev=0x0]
/dev/sg1: scsi0 channel=0 id=0 lun=1 [em]
Generic USB CF Reader 1.01 [rmb=1 cmdq=0 pqual=0 pdev=0x0]
/dev/sg2: scsi0 channel=0 id=0 lun=2 [em]
Generic USB SM Reader 1.02 [rmb=1 cmdq=0 pqual=0 pdev=0x0]
/dev/sg3: scsi0 channel=0 id=0 lun=3 [em]
Generic USB MS Reader 1.03 [rmb=1 cmdq=0 pqual=0 pdev=0x0]
/dev/sg0 /dev/sda
/dev/sg1 /dev/sdb
/dev/sg2 /dev/sdc
/dev/sg3 /dev/sdd

But whenever I try to mount /dev/sda1,...,/dev/sdd1 I get nothing??. I have
a 512mb Memory Stick Duo Pro, that I know contains file,s but there is no
way I can view them in Gentoo.

I also tried adding a UDEV rule, as described in
HOWTO_USB_Mass_Storage_Device, but was unsuccesfull there too.

The card reader works fine in my dual boot Windows 2000 SP4, so it should be
connected up properly.

Any tips are greatly appreciated.

It seems that if I put the card in the reader, and look at dmesg, I get

SCSI device sdd: 960512 512-byte hdwr sectors (492 MB)
sdd: Write Protect is off
sdd: Mode Sense: 03 00 00 00
sdd: assuming drive cache: write through
sdd: sdd1
FAT: bogus number of reserved sectors
VFS: Can't find a valid FAT filesystem on dev sdd.
FAT: bogus number of reserved sectors
VFS: Can't find a valid FAT filesystem on dev sdd.

But the card came formatted from Sony. I don't want to mkfs it, afraid of my
Sony Ericcson phone not being able to read the card anymore.

It would seem that one might have a proprietary file system?

Nope. But I looked at sg_scan -i && sg_map output, and decided that this was
right. Then set up my fstab like;

/dev/sda1 /mnt/sdcard vfat noauto,user,exec,sync 0 0
/dev/sdb1 /mnt/cfcard vfat noauto,user,exec,sync 0 0
/dev/sdc1 /mnt/smcard vfat noauto,user,exec,sync 0 0
/dev/sdd1 /mnt/mscard vfat noauto,user,exec,sync 0 0

Now I can actually mount a card, and read/write to it. But unmounting
fails.....it's just ignored. Also, I can't mount other cards, once one has
been mounted.

Does the "users" option (instead of "user") work?

Where did you get the disk names from? Usually they are not always the
same, and people are apparently supposed to create udev rules for their
card readers.

An example of such entries is on
<http://www.nasauber.de/linux_know_how/?id=cardreader> (text in German,
but the example rules should be readable for non-German speakers).

You can use something like

udevinfo -a -p /block/sdb

to find the SYSFS (oder ATTRS) entries for your device.

I guess the problem is that he didn't unmount the card, then he can't mount
another on the same device until he has unmounted, the problem do much likely
come from what you already pointed out from the "user" option that should have
been 'users'.

No. I have not been able to mount a card, when "users" are set.

From the sg_scan -i && sg_map, in my first post in this thread.

Yes, if I set up UDEV to handle this(as in
http://gentoo-wiki.com/HOWTO_USB_Mass_Storage_Device), but when I tried,
that failed too.
