Memory Card reader not appearing in /dev [SOLVED]

jdc · 2014-09-17 00:34:57

I have a memory card reader on my laptop that isn't showing up in /dev, dmesg, journalctl, parted, and fdisk. I've tried running the following, but it didn't work:

# echo 1 > /sys/bus/pci/rescan

I tried running a few modprobes, and I tried rebooting with a memory card inserted into the reader, but neither worked. I checked lspci, but it doesn't show up there. The card reader itself is functional when running Windows 8, I used the same card and it worked fine. Is there anything else I can try? Install a driver maybe?

EDIT
Interestingly enough, it does show up in lsusb (I think), but I still don't know what to do about it.

SOLUTION
Need to load rtsx_usb_mmc module

Memory card readers are often connected to the USB bus. Does lsusb show anything?

Here you go; there's a card reader controller. What happens now?

You could try manually loading rtsx_usb_sdmmc and see if it works. I don't see any other possible driver candidates for your hardware. The other possibility is that arch lacks the driver for that hardware.

Use your google-fu and see what you come up with, maybe the solution is easy but not obvious at first glance.

In kernels up to 3.15, the rts5139 staging driver should handle this reader. rts5139 is gone in kernel 3.16, there's rtsx_usb and rtsx_usb_sdmmc instead, they should work. Check /etc/modprobe.d, maybe you have them blacklisted there.

jdc · 2014-09-17 13:55:51

I just spent an hour trying to figure out how to get the rts5139 drivers, which were apparently phased out for the drivers you guys mentioned hehe. I probably could've saved myself an hour if I had just checked back. Thanks so much, rubenvb, for pointing me in the right direction, and thank you, emeres, Gusar, and R00KIE, for providing the solution.

@R00KIE: Definitely not obvious because the old solution is different from the new solution
@Gusar: Only have pcspkr blacklisted, maybe it's cause of the modconf hook in mkinitcpio? I could probably just add it to the MODULES section of mkinitcpio.conf and rerun it, I guess.

Again, thank you for all the help.

Gusar · 2014-09-17 14:15:17

Hmm, the module doesn't load automatically? Then you'll need to set it up yourself. I don't see the need to add it to the initcpio, just create an appropriate config file in /etc/modules-load.d (check the modules-load.d manpage)

Yeah, just read about that a few moments ago on the wiki. Thanks!
