Public bug reported:
The internal reader in my Acer Aspire 8943G laptop from O2 Micro
manufacturer doesn't work at all. It doesn't mount any memory card nor
recognize that a card has been inserted (system log doesn't show any new
message when I insert or remove a card).
I have tried using A-DATA 16GB SDHC Class 6 and a very old 16MB long
MemoryStick or whatever it was.
I have also tried some workarounds posted all over the Internet
including adding "options sdhci debug_quirks=0x40" into a configuration
file in /etc/modprobe.d but it didn't work. Somewhere in the Internet,
there had been also a linux driver for the O2 Micro SmartCard reader,
but I don't really think that it is suitable for my card reader and,
anyway, as the driver was quite old, the download link didn't work.
I tried Ubuntu Oneiric Alpha 2 daily build today and again, the card
reader doesn't react on card insertion at all.
