I'm having a hard time with this one. I have an ACER ASPIRE ONE 756 and installed Ubuntu 12.04 LTS on it.
Everything works (with a little tweaking here and there), but unfortunately the build-in card-reader terrebly fails.
I know that the BCM57765/BCM57785 is a combined card-reader / wired-lan 1gbps module. The wired lan works fine, but the card-reader fails. It seems to be recognised, but I can't access any SD card. As it doesn't even recognise it in tools like MountManager, the problem seems deeper than just an auto-mount problem.
Can anyone help me out? I really need this to work, and there seem to be a lot of people having issues with linux and card-readers, but unfortunately I haven't found a solution yet.
