Re: [tlug] SD card reader not reading SD cards

Botond ,

Thanks for responding.

Strangely, my SD card is now functioning again, though I'm not 100 
percent sure what I did to solve it.

In the kernel, I confirmed that I have CONFIG_SCSI_MULTI_LUN=y, so the 
kernel should be ready to accept support a multiple card reader. But it 
was already set before I checked it.

I also read on the web about how SD cards are considered SCSI devices 
and such.

It seemed to be the case that I needed to edit a file called 
/etc/lilo.cnf and set "max_scsi_luns=6". But I couldn't find a lilo.cnf 
on my system, and so I was going to ask about it in this message.

So I don't think I actually did anything to change any settings, but I 
put the card reader to see what, if any, dmesg output there would be for 
the purpose of responding to your posting. And I was fully expecting at 
best errors but most likely nothing at all.

Much to my surprise, an icon appeared on my desktop, and dmesg said:

Huh. That's good, I guess.

I can't seem to reproduce the problem of the SD card not working, even 
though it definitely was not before.

I wonder if I should worry that it will go away again.
