openSUSE 11 SD card problem in Acer Aspire one

English Hardware

I installed openSUSE on Acer Aspire ONE. However, the SD card reader did not work. I can not find any device in /dev, just like sdb, sdc or sdx…

The lspci is as follows

First:
It seems that no device about SD card be loaded in my system.

Second:
My computer just has 3 USB sockets. However, in the result of “lspci”, there are 5 USB devices. Is it possible that 2 of the USB devices are SD cards?

Do I have to load the SD card module by myself? If yes, can anybody tell me how to do (or show me some page to read)?

I have not loaded RC1 yet, but usually the SD Cards are in “/mnt”.

I just realized that the Aspire One has 2 card slots. If you mean the card slot on the left, then the first question is whether you pushed the card in all the way till it clicks. The card should mount in “/media” (not in “/dev” and not in “/mnt” – sorry about the mistake earlier). It should also show up automatically on the desktop.

I tried putting an SD-Card in the right side slot and from what I see, you are correct. That slot does not seem to be hooked up. You should report this bug in Bugzilla.

Ok, first, let me say that I am still running Beta 5 and will be loading RC1 fairly soon. I have to go to work now, but I just tried a card in the right side slot and it seems to be working too now.

Try putting the card in the slot before you boot the computer and see if that makes a difference. I will try it again after I load RC1 and see if I can give more info then.

I think that when a device like USB pluged into my computer, it must appear in “/dev”, like “/dev/sdb1”. Then my system will mount “/dev/sdb1” to “/media/disk” (or I have to do it manipulatively), right?

So, I think that if I plug a device into my system, I should see it in “/dev”, right? If it didn’t appear in “/dev”, isn’t the module be loaded?

Could anybody tell me the above is right or not? If right, I think I have to load the module manipulatively and how can I do it?

What you are saying is essentially correct. However, let me first say that I have installed 11.1 RC1 in an Acer Aspire One and have found the following:

  1. The “left side SD-Card slot” is working correctly. If you have the Desktop displayed and put a working card in the slot (remember to push it in all the way) the card will “mount” and an Icon for the card will be displayed on the Desktop. You should “Unmount” the card before removing it, but if you have not made any changes on the card, then you can simply remove the card without any problems. You can then insert another card, and so on.

  2. The “right side Multi-Card Reader slot” is not working correctly. It will only work if you insert a card BEFORE you turn on the computer. If you have a card in that slot before you turn on the computer, it will work properly for that session. That means you can “Unmount” that card and put in another card, and so on, and it will keep on working normally until you turn off the computer.

In either case, the card should be mounted automatically. You do NOT have to mount it.

Now, regarding what is in “/dev”:

A card in the left side SD-Card slot will use “mmcblk0” as the base and “mmcblk0p1”, etc. as its partitions. An SD-Card in the right side Multi-Card slot will show up as “mmcblk1” with “mmcblk1p1”, etc. as its partitions. I do not know what device names are used for the other types of cards.

OK~ Very thanks. My SD-card is working now~ (openSUSE 11.0)
