EDIT: I've found the thread you were talking about. it seems I didn't read the original post properly it was a problem with the MS troubleshooting methodology being pragmatic I'd argue its just general inferior troubleshooting. Though Linux has its fair share of demons also.
Well I'm not going to complain about inferior tech support or poisonous people within a community as it happens everywhere and I'd be here all day.
However if you still have problem try this
Code:
sudo dmesg
sudo lshw
both before and after you insert a card and post the output, Linux version and the card reader type would be helpful also
Failing that try this
Code:
sudo rmmod tifm_sd
sudo rmmod mmc_block
sudo rmmod sdhci
sudo rmmod tifm_7xx1
sudo rmmod tifm_core
sudo rmmod mmc_core
sudo modprobe -r tifm_sd
sudo modprobe -r tifm_7xx1
sudo modprobe -r tifm_core
sudo modprobe -r mmc_core
sudo modprobe -r mmc_block
sudo modprobe -r sdhci
sudo modprobe tifm_sd
sudo modprobe tifm_7xx1
sudo modprobe tifm_core
sudo modprobe mmc_core
sudo modprobe mmc_block
sudo modprobe sdhci
A bit big but just to be thorough.
Insert the card and see if it works
