MMC card reader -- howto configure?

[beijingjj]

I have a new Area51 laptop. It comes with a built-in MMC reader. When I insert a card in Linux (FC3) the system sees nothing, so obviously it must not be configured. Does anyone know how to configure it? I'm not even sure which, if any, of the devices from lspci it is (below)

I have never done it but it is possible that this may help you: http://www.cs.sfu.ca/~ggbaker/personal/cf-linux

I think this addresses using an external USB mmc reader, which works fine without any extra configuration. Thanks, though.

Good news and bad news

First the good news

I found a driver for this device.
http://www.musclecard.com/sourcedrivers.html

under
O2Micro Smartcardbus PCMCIA Smartcard Reader
ftp://scrdriver:scrdriver@209.19.104...nSource.tar.gz


Now the bad news

This driver was written for the 2.6.13 linux kernel and I'm using the 2.6.16 kernel. The pcmcia structures have changed and I'll have to hack a bit before I can get these drivers working

I did a make in the kernel module directory and got error messages like so
/root/test/OZSCR_2.0.3_Kern_2.6/src/ozscrlx-2.6.13/ozscrlx.c:205: error: unknown field ‘attach’ specified in initializer
/root/test/OZSCR_2.0.3_Kern_2.6/src/ozscrlx-2.6.13/ozscrlx.c:206: error: unknown field ‘event’ specified in initializer
/root/test/OZSCR_2.0.3_Kern_2.6/src/ozscrlx-2.6.13/ozscrlx.c:207: error: unknown field ‘detach’ specified in initializer

and saw some articles mentioning the relevent changes in pcmcia_driver stucture

it looks like .attach has been replaced with .probe
.detach with .remove

and .event has been moved out of this structure into the unified event handler
(I have no idea what this is and how to use it)

I'm sure some others that have more experiance with writing device drivers than me could solve these issues in a jiffy but this is going to take me a while and I'll have to recrute some more experianced people to help.

I tried a quick replace and built a module when I tried loading I got these errors in my dmesg

ozscrlx: Unknown symbol pcmcia_deregister_client
ozscrlx: Unknown symbol pcmcia_register_client

So those need fixed also

I found information on these changes here
http://lists.infradead.org/pipermail...er/002604.html
and
http://lists.infradead.org/pipermail...er/002612.html

if someone can help me out building it correctly I would greatly appriciate the help thanks.

p.s.

to install the drivers you'll need to get
pcsclite from http://pcsclite.alioth.debian.org/
it built and installed with no issues for me
