Question SD slot not working on Acer aspire one with Ubuntu 10.10 desktop


My sd slot is not working at all, doesn't recognize it. I think it may have something to do with having the desktop version installed but I could be wrong. I was only introduced to linux 4 weeks ago and am not very familiar with it, but already know I like it more than windows!

Any help as to a driver I could install or something to make it work would be great! I have tried three different sd cards and they all work in my other laptop with Windows 7.

Are you getting the message - MMC:0 UNRECOGNIZED CONTROLLER VERSION (XX). MAY CAUSE PROBLEMS. - when you start up? (XX representing a numeral, 16 or 02 or whatever). Also what kind of system do you have? what card are you using? try starting the terminal and typing:

You should get something that looks like this:

06:03.0 CardBus bridge: O2 Micro, Inc. OZ711MP1/MS1 MemoryCardBus Controller (rev 20)
06:03.2 SD Host controller: O2 Micro, Inc. Integrated MMC/SD Controller
06:03.3 Bridge: O2 Micro, Inc. Integrated MS/xD Controller
06:05.0 Network controller: Intel Corporation PRO/Wireless 2915ABG [Calexico2] Network Connection (rev 05)

Woops, Asked what system your using ... ignore that, I see Acer Aspire right in the title.


Found this using google:

Go into terminal, type:
$ sudo gedit /etc/default/grub

Change the line GRUB_CMDLINE_LINUX_DEFAULT =”quiet splash” to:

GRUB_CMDLINE_LINUX_DEFAULT=”pciehp.pciehp_force=1 quiet splash”

Restart, and there you go!

Please note that I found this, and do NOT know what the outcome may be.
You may want to search the command's on google, and see what it says. Hope it helps :-)

Try a few different versions of live cds. They then to allow root or higher access and by using more versions you may find one that works and gives clues to what it is.

Laptops are really weird. Some have common parts behind bridges.

Knowing how windows views the device may help also.

Ubuntu kernels seem to require "pciehp.pciehp_force=1" on the kernel line in /boot/grub/menu.lst (or in the appropriate place in /boot/grub/grub.cfg if you're using grub2). Fedora kernels don't require this messing around. I have both on my Aspire One (AOA150), so I'm used to this situation.

I have tried a couple of these suggestions but nothing seemed to work. My teacher found me a driver to install, however haven't had the time to do anything about it yet! I hear that Ubuntu 11.04 has fixed this issue with Acer netbooks and I plan on upgrading sometime this week.

Thanks for the Suggestions!
