As requested by Mark, I’m making a thread about my stupid Acer Aspire 6920 LF1 and it’s stupid 6 in 1 card reader. It won’t work unless I put in the card of choice and then reboot the damn laptop. And only then it’ll pick up the card. We’ve already tried using instructions to an almost identical problem with the Acer Aspire One.
see here : Clicky
These instructions never worked, so this thread is basically here until Mark has found some mad solution 
Attached is my hardware list (sudo lshw).
can you also post the output from:

Something to try…
gksudo gedit /etc/default/grub
find the line that reads:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
and change it to:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash sdhci.sdhci_force=1"([b]DO NOT[/b] copy/paste the [b]sdhci.sdhci_force=1[/b] from the above quote... for some reason it ends up as [b]sdhci.sdhci_fo rce=1[/b] .. at least it does on my system)
SAVE and exit gedit.
back in the terminal run:
sudo update-grub
Now REBOOT and then see if the card can be hotplugged.
For clarity, you are adding:
sdhci.sdhci_force=1
to GRUB’s boot line.
If that doesn’t work… Can you boot with a card inserted, then run:
lspci -vnnn
and post the output.
also run:
lsmod
with the card inserted at bootup… and again without the card inserted at bootup, but inserted just prior to running lsmod
so we can see if there are any differences in what gets loaded.
Oddly enough I was expecting an AMD chipset with a JMicron controller… but it appears that Acer used both AMD and Intel chipsets on the 6920 series…
Check the attachments.
also run:lsmod
With inserted at bootup…

Try this… without the card inserted at boot (so the card isn’t detected)
Once booted… insert the card and run:
sudo sh -c "echo 1 > /sys/bus/pci/rescan"
and see if the card is detected.
I didn’t even run this, but here’s something freaky… I was taking out the card, and accidentally pushed it in. Laptop detected it straight away, no waiting times. I tried it 3 times, and it works… No idea what’s happened there, but I’ll reboot the system later on, and see if anything changes…
