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.

BR
