 Posted: Thu Sep 03, 2015 11:07 pm Post subject: Detect SD card reader, not the card. |
 |
|
Hello fellow gentooers:
I fell like this is a silly question but I fell befuddled by this...
How can I know what my SD card reader is?
I've seen the suggestions to make
| Code: |
dmesg | grep Something_Relevant
|
but I do not know what that "Something_Relevant" could be.
I have tried these
SD
MMC
Ricoh
Card
By the way, lspci and lsusb do not seem to show anything related:
| Code: |

External or internal?
If the reader is mounted internal, you can try to unmount it. |

It depends
some sdcard readers are usb ones too, even when they are built in.

it may be smart to boot up a distro / livecd with a lot of hardware support. and check waht lsmod shows, ...
or you may just rebuild your kernel with a lot of kernel modules and see than lshw output... |

Thanks crew:
Well I intalled lshw and doesn't show anything more interesting than dmesg or lspci/lsusb but more detailed.
I booted right now with the SystemRescueCD and the kernel modules listed are these:

I do not even know which could be suspected of taking care of the card reader. But I have the suspicion that no one of these does it...
The /dev directory looks as this:

Could it be md0?
I am getting the strange felling that the SD card reader is not even conected to the motherboard. I check if the BIOS lists it as maybe some possible boot device, or i may have to disassemble the machine.

I have an integrated card reader on the Pci bus of a laptop, the module who drive it is sdhci-pci. I have an integrated card reader on the Usb bus of an other laptop. According to lsusb -t, the module is ehci-pci. I can see each of them using lspci and lsusb.
Until you insert an Sd card into the card reader, you will not see any device file from the card reader controler. A card reader is a controler on a bus and an Sd card is a mass storage connected to that controler.

wpkzz,
I'll guess that the card reader is disabled in the BIOS, since its not listed in lsusb nor lspci.
It will appear as one /dev/sdX entry per slot when all is well.
/dev/md0 is the first raid device.
If you wgetpaste dmesg, we can look it over.

| I would increase the speed of search much, if you open the case of the your computer. |

wpkzz,
Its not there. Its either :-
a) an option thats not fitted to your hardware - you have the slots but there is no hardware.
b) broken
c) disabled

Well, following Keruskerfuerst advice, I opened the computer case and it seems to be there. But it is part of a front control panel that has an information display and they are connected with the same cable to the motherboard to a port labeled simply front control panel. The usb ports on the front are, in contrast, connected with their own cable to the adecuate ports in the motherboard. I did not dare to open more the machine, so I couldn't see if the devices have a name/brand/model or anything.
I am beggining to think that it is a PXE security device only for booting. Seems weird though... couldn't it be used as a normal port
afterwards?
Thank guys |

wpkzz,
Pictures may be useful.
Also count the wires it the front panel control cable.
There are normally two per switch and two per LED.
A USB port neeeds four.
the motherboard info from dmidecode may be useful too.
