Description of problem:
Hello.
I have not much of an idea where to start on this one, so logging a bug.

I have a multi-card reader, and I cannot use it under Linux.

Any info on how you solved this would be great.

Comment 4 Pete Zaitcev 2005-09-13 19:22:26 UTC 
How does it actually look, is it a little PCB with an SD connector
which plugs in a Cardbus slot, like a normal CF adapter? Any URLs?
Comment 5 Need Real Name 2005-09-13 21:01:10 UTC 
It's built into the computer, it looks like this:

(sorry for the small pic)

The PDF for the specs is here:

Page 5-2 has an annotated photo of the motherboard.
Comment 6 Dave Jones 2005-09-30 06:12:56 UTC 
Mass update to all FC4 bugs:

An update has been released (2.6.13-1.1526_FC4) which rebases to a new upstream
kernel (2.6.13.2). As there were ~3500 changes upstream between this and the
previous kernel, it's possible your bug has been fixed already.

Please retest with this update, and update this bug if necessary.

Thanks.

'fraid not. Still broken.
Comment 8 Bill Nottingham 2005-09-30 22:02:34 UTC 
What is the modalias under /sys/bus/pci/devices/0000:02:0c.1 ?

Comment 10 Bill Nottingham 2005-09-30 23:36:18 UTC 
OK, so that's not obviously claimed by something.

Presumably, there are no messages in dmesg if you actually plug in a card.

Out of random curiousity, I'm assuming 'modprobe wbsd nopnp=1' doesn't cause
it to magically work?

I suspect it just may be hardware that there's no driver for, yet.
Comment 11 Bill Nottingham 2005-09-30 23:43:00 UTC 
In fact, some looking with Google shows there is currently no driver for this
card reader, and no specs available to write one. If the trick with wbsd doesn't
work (attempting to use the Winbond SD/MMC interface), then I'm not sure there's
really anything we can do until specs become available and the driver is
written. Sorry.

I tried the modprobe suggestion, but unfortunately it didn't work. dmesg stays
silent. Thanks though!
