SD/MMC Card Reader not detected

Hello!

I am struggling to get the SD/MMC Card Reader that is built in into my monitor to work. It is connected via USB. All the USB ports on the monitor work correctly. The card reader should works as well (it did on Xubuntu). I couldn't even find any drives with "fdisk -l" or "df -h". Also it was not listed in "lspci" or "lsusb", at least I didn't recogize the name. On Xubuntu it was called something like "SD/MMC Card Reader ... ".

Can anyone help me out here, I didn't find a wiki article on SD Card Readers? It shouldn't be too difficult to get it to work as it has worked on any operating system (Windows, OS X, Ubuntu) so far, without driver installation.

EDIT:

I don't know what just happened, maybe someone can draw some conclusion. I "modprobe sdhci" to see if this would spark something. But nothing happened. I then rebooted and forgot to take out the sd card. And when I got to the tty login and got a bunch of

usb 3-4.1.1: device descriptor read/64, error -110

So I plugged out all the usb devices and rebooted again. Things worked fine, after that. Then I rearranged my usb plugs and rebooted with the SD Card inserted and got this

sd 6:0:0:0: [sdc] no Caching mode page found
[sdc] Assuming drive cache: write through

Not sure if using the wrong caching style will cause problems. But now the partitions of the SD Card mount, the controller however still doesn't list. This is kind of strange.

What type is the monitor? Also, mine also doesn't show in lspic, but it is in `dmesg|grep scsi`. Does nothing happen when you insert a card?

Re: SD/MMC Card Reader not detected

no Caching mode page found is nothing interesting, so everything actually works fine

Mine does that most times I try to use it but it will work eventually.

I have attributed this to a cheap-ass p**s-poor card reader in my laptop...

Could you post the output of lsusb   ??
