Did this change with hardware?
I bought a cardreader about 2004 when I got a digital camera, to read
cmpactflash cards. It was fine, read different types of cards though I
never used it with others.
Then I started with SD cards. The reader worked initially, then with
other cards didn't. Then I realized the cardreader was so old that it
didn't know how to handle SD cards larger than 2gigs. I had to buy a
newcardreader.
And even then, I had problems. Linux saw the cardreader but not the card.
I fiddled and then discovered I needed to configure things so it would see
more than one of the card options. SOmething about setting the number of
luns, I found it in a text about using multi-card readers with Linux.
I did what the article said, and bam, the cardreader worked.
It also solved the problem I had of not being able to see the microSD card
in my Sansa Fuze when the latter was mounted. It was the same issue.
So if this problem came up because of new hardware, or a new install of
Linux, I'd look into this LUNs business.
