SD card not detected unless inserted at boot time

[Jerome]

Hi.

My desktop is a Dell XPS 630i. It has a SD card reader on the front panel.

It used to work until about a few months ago (I guess, I don't use it that often). Now, the SD card is undetected when inserted.

If inserted before boot, then the existing partitions are available in thunar. I can remove and insert back the card in the reader without it being detected. I can mount and unmount the partitions. But if I "eject" the partition, then the card is not detected anymore even if pulled out and pushed in again.

Not much in dmesg (the drive is /dev/sde, and there are two partitions in the card, it is a raspian OS) :

[  727.401337] sde: detected capacity change from 2013265920 to 0

When I click "eject" or manually remove the card, it says "capacity change from 2013265920 to 0".

I'm using Jessie, with the latest 3.11 kernel from experimental, but the issue was there with 3.10 and most probably older kernels. I tried to go back in time using older kernels (down to 2.6, I think the reader worked at that time) without succes, which may indicate it does not depend only on the kernel.

I don't have any "power saving" setting in the BIOS I could disable. And I didn't modify the BIOS, even the BIOS settings, in the last months.

I'm pretty sure it is a software issue as it worked with a knoppix 7-something.

The

Code: Select all

echo 1 > /sys/bus/pci/rescan

command I've read about does not seem to help. It is supposed to force the detection but nothing in dmesg and no volume available in thunar.

I found a workaround yesterday. If I launch gparted (needs admin privileges), the SD card is detected. Like if it forced the detection. Sometimes, I have to specify the path explicitely to get it to appear :

Code: Select all

gparted /dev/sde

This workaround is not satisfying but I'm sharing it anyway in case it could help anyone.

Besides, I'd like to have this bug fixed, but I don't know against which package I could file a bug.

Any idea ? Could it be some misconfiguration on my side ?

I forgot to mention that the ouput of lspci, lsusb and lsmod are identical whether the card is detected (inserted before startup) or not. (More precisely, lsmod differs, but only on the order of the lines.)

I also recorder Xorg.0.log and dmesg, but there are many differences, which I guess has nothing to do with this issue, and I don't know what to search for specifically.

I have used a similar workaround for a long time, not sure where the fix is, but i think the problem is down deep somewhere, device is in floppy group and only real old guys know how to use that stuff.

[Jerome]

Do you remember when it stopped working correctly ?

[bw123]

Do you remember when it stopped working correctly ?

it has never popped up /dev/sde1 when card is inserted, i started on squeeze 2.6.32 or maybe .29 and played awhile with it. I thought it was a udev issue and played with some udev rules but never got it working. Not sure if that's in the right direction.

device is a 5 in one multicard reader, works fine when card inserted at boot, won't sense media. works fine once it's hit with blkid, fdisk or some other tool that gets the different card slots with media to initialize. It's really like a glorified floppy, you know the old days you had to "insert disk with command.com in drive a:" and all that crap.

[Jerome]

I believe I got my computer in august 2011 and installed a Debian testing (Wheezy) on it. I'm almost certain it worked correctly (card detected anytime) from then to not so long ago.

[bw123]

just out of curiosity i booted a knoppix 6.7 live cd to cli and it does work correctly sensing media until i run

Code: Select all

apt-get purge hal

maybe that will help you better understand the issue, the kernel was 2.6.39 not sure of hal version you could probably look it up.

[sgosnell]

You might try going to Teh Google and putting in "automount removable drives debian".

[bw123]

You might try going to Teh Google and putting in "automount removable drives debian".

In my case, you can't automount what isn't there, udev doesn't see the media when it is inserted. I've tried autofs, usbmount, several other packages. i've done web searches for about two years on and off, but yeah, do your own research by all means. a good web search never hurts.

hal would probably do it? but i don't see the point in going that way for an sdcard i can use fine with a little script, what's the big deal with automatic stuff anyway?

Code: Select all

#!/bin/sh
# sdcard script workaround

DEV=sde
PART=1
MNTP=/media/sdcard

if test -e /dev/$DEV$PART
   then mount $MNTP
   else 
   {  /sbin/blkid /dev/$DEV
      if test -e /dev/$DEV$PART
         then mount $MNTP
      fi
   }
fi

[sgosnell]

If blkid shows the drive, then the system knows about it. Getting it mounted is another issue, and can be difficult. I haven't seen your particular issue, so I'm a a loss as to what else to suggest. I should also say, though, that the card won't always be found at /dev/sde.

Jerome:
Desktop card readers are almost 100% USB devices - so it would be helpfull, if You'll provide "lsusb -v" output with the card inserted.
..and btw: I've had few MBs with MCP51/C51/C55 chipset - it is buggy like hell - the worst in NV history, I think. NV wasn't able to provide stable drivers even for windows, so f.e. they took linux ethernet driver (FORCEDETH) and ported it to win - it was more stable solution

regards.

This would indicate that hal is required. Heard about it but I don't have any specific knowledge. I can check I got that installed / running.

If blkid works, I suppose I could have it croned to run every second and I'd have a seemingly instantaneous detection. But that sucks...

If blkid shows the drive, then the system knows about it.

Yes, that's the good point. It means there has to be a software solution. The ugly one being the blkid polling script. We could identify what specifically in blkid triggers the detection.

Desktop card readers are almost 100% USB devices - so it would be helpfull, if You'll provide "lsusb -v" output with the card inserted.

OK, I'll try to do that soon both with and without the card detected.

Thank you guys for the support. I'm not sure many of us are concerned, but I'd be happy to get this solved in the distro (vs. ugly local workaround).

Does this tell us anything ?

It was late yesterday night. When I get back to the machine I can lsusb -v, this time without the card, and compare both.

[tomazzi]

Well, maybe I'm blind, but I can't see the card on the list - the only storage device is TEAC (Mass Storage) ...
So, was this listing made without card inserted? or do we have a problem here?

regards.

[bw123]

might be relevant, not sure whether it's udev or kernel?

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=648810
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=696509

Just for the heck of it, here's the device I'm using. I thought the problem might be related to the mtp_probe errors from udev on bootup, but when I filed my bug report I was told it wasn't a udev bug so I just gave up trying to help.

I can't remember if I had the partition on the card mounted, but it was in and detected.

I'll do it again with and without, and I'll do a diff.

Edit: @bw, I had not seen your post. Your script is great.

I did a lsusb -v in all those cases, and got the same output each time:

- Card detected at boot
- Card detected at boot then mounted
- Card detected at boot then mounted then directory opened
- Card detected at boot then mounted then directory opened then card ejected
- Card not inserted at boot
- Card inserted after boot and not detected
- Card inserted after boot and not detected then detected after blkid

Not sure about the bug reports. My USB sticks are detected.

so, if you put the card in and do this in a term your automount stuff takes over and finds it right?

$ /sbin/blkid /dev/sde

Yes, exactly.

And this is what happens in dmesg when I do that:
