[Solved] Memory card reader Ricoh Co Ltd R5C822 not working

I have a thinkpad t500 with memory card reader, but when I insert an sdcard nothing happens. The sdcard works on an usb card reader and in the camera. I have also tried with another sdcard. The card reader used to work under debian before I switched to arch half a year ago. There is no /dev/mmc* device. It doesnt show under gnome-disks or fdisk -l.
Any help would be highly appreciated.

$lspci -nn | grep SD:

After a reboot it works again. There must have been some update in the meantime I completely forgot about ...
Sorry.
