Thread: RTS522A PCI Express Card Reader under openSUSE Leap 42.1 (x86_64)

    Default RTS522A PCI Express Card Reader under openSUSE Leap 42.1 (x86_64)

    Hi folks

    I am running openSUSE Leap 42.1 (x86_64) and have to set up my SD card reader

    I have the following card reader:
    Code:
    computer:/home/user # lspci |grep Card
    02:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTS522A PCI Express Card Reader (rev 01)
    So I found the website http://cateee.net/lkddb/web-lkddb/MFD_RTSX_PCI.html which states that you need the module rtsx_pci.
    I loaded the module, which looks good to me:
    Code:
    computer:/home/user # lsmod |grep rtsx
    rtsx_pci               57344  0 
    mfd_core               16384  1 rtsx_pci
    But then if I issue
    Code:
    fdisk -l
    it does not show up. What am I missing here?

    Thanks a lot!

    Please excuse my ignorance, but my knowledge ends here. I don't know how to interpret that line...
    Do I have to compile that C file? Or which command do I have to issue?

    thanks

    Your Card Reader only works with Kernel 4.4 and higher.

    In openSUSE leap, Kernel 4.1 is working.

    Ok, great, I upgraded to Kernel 4.7.0 and now it works out of the box.
    Thanks!

    If you still have kernel 4.1.x installed and are interested in testing for the
    benefit of other users not willing/being able to install a newer kernel, please
    respond.

    Yes, I still have the 4.1 kernel along with 4.7.0.
    My kernel knowledge is certainly very limited, but if I can be of any help, let me know.

    Well, then let's start.

    I need to know exactly which kernel 4.1 is installed.

    rpm -qa "*kernel*"

    Before going into great detail, let me just elaborate the idea in a nutshell.

    - Use the code from kernel >= 4.4 and make it run with 4.1.

    - I have already done this, so you will not need to build/compile anything,

    - Before telling you "try this package here" I need to know what "this package"
    will be (i.e exact kernel version and flavor), that's why I need the output of
    the rpm command above.
