Trouble w/ USB card reader [SOLVED]

kiss-o-matic · Guru Joined: 19 Jul 2004 Posts: 423 Location: Tokyo

I have a multi-card (Memory Stick, SD, etc.) card reader that I'm having a hard time getting to work.
I followed this, but dmesg isn't really telling me what I need to know.

This is how I configure my fstab for my multi-card reader.

But I don't have any device like that... that's the issue.
I have... sdb... and that's about it.

Does your kernel support multiple LUNs?

I've got
* Device Drivers->SCSCI device support

That should cover it, no?

This falls under devices like usb sticks. At least I have that enabled in my kernel.

Well, I've enabled just about everything I can think of in the kernel, still to no avail. It works fine on my other (worse) linux box which I'm trying desperately to decommission. Basically the machine knows there's a USB device there, but has no clue what to do with it.

EDIT: Now, I guess I've gone back a step.
Plugging the device in, I no longer have /dev/sdb
dmesg only shows this:

Partially solved.
I wasn't booting the right kernel. I now haev /dev/sdb1 when my Compact Flash card is in the multi-card reader, but it doesn't pick up SD cards. They work on other machines though. :/

I have a very similar problem. I had the "classic" Gentoo/Gentoo Wiki USB mass storage setup, enabling a simple plug-and-play of the USB device, it appears on my KDE tray under media, drop and drag files, and so on. I haven't used my Gentoo box for a few weeks, but do remember upgrading udev a the time ...

Now, none of my USB sticks or drives are automounted. I no longer have any sdX under /dev.

I have Gentoo Sources 2.6.22-r8.

My issue was solved. The "scan multiple LUNs" option under SCSI devices in the kernel was the last kernel.
I think you have a different issue... I never got any type of errors.
