Public bug reported:
My Toshiba A70 laptop's SD card reader with PCI ID 1524:0550 (part of
an ENE CB-710/2/4 Cardbus Controller) doesn't work with Linux. I
haven't tried Ubuntu pre-gutsy, but it hasn't worked with Gutsy, Hardy,
or Intrepid. I've never seen it work under Linux, so AFAIK this isn't a
regression. This hardware is a few years old...
There are various bug reports on very similar hardware, but most
reporters haven't been careful to report PCI IDs, or even choose non-
generic titles, so the SD card reader bugs are a mess. I'm opening a
new one that's just about this specific hardware, instead of trying to
revive one of the old bugs.

(see attached dmesg output for the full thing. I can attach a full lspci -vvnn
if anyone wants.)
When I insert an MMC or SD card, the light on the card reader flashes for a
second, then goes out. Nothing is reported in the kernel log, and no /dev/mmc*
appears. The hardware works with these cards under another OS, so it's the
hardware is physically ok. Inserting a card increases the IRQ count for mmc0
by 2, removing a card generates 1 interrupt.

Other than that, a whole lot of nothing happens. Unloading and reloading the
module hasn't helped, so it's not an intermittent problem.
This is _not_ the same hardware that Leu has on bug 31440. I think I
have the same hardware as the original submitter (who left -nn out of
his lspci args, so I'm not sure), but since that bug has been closed
(wontfix) based on Leu's hardware, it would probably be confusing to
reopen it.
It's also not the same hardware as bug 99648, since mine only has 4
subdevices (.0 - .3), not 5 (.0 - .4). And the PCI device name is
different, although that might just be an older PCI name database...
Someone thinks this hardware has never worked under Linux:
"The 1524:0550 is a dead Dodo. I've never seen any reports of it working at
all." from http://osdir.com/ml/linux.drivers.sdhci.devel/2007-09/msg00026.html
But someone else does seem to have had success:
http://marc.info/?l=linux-kernel&m=116758515323702&w=2
So maybe I should go try an old livecd on my laptop, if I haven't
overwritten my CDRWs...
