The problem is that the device is not detected by the kernel .
it is not visible in the dmesg output and not visible in the output of
fdisk -l.
But other usb devices work fine - a usb stick is detected and mounted
automatically.

/dev/sdh -is the cardreader device.
after inserting a sd card nothing happens - /dev/sdh1 doesn't appear,
but it appears if I run fdisk -l /dev/sdh for example.
It appears as though udev is working correctly. If sdh1 appears when you plug
in the reader with the card already inesrted, udev is definitely working.
What appears not to be working is the daemon that periodically opens and
closes USB devices in the event that a medium was plugged in (used to be hald,
I think). Remember that USB1 and USB2 are master/slave; the host end must
initiate and perform all communication. If the daemon is malfunctioning, the
system will not detect cards inserted into readers: the USB device cannot
autonomously notify the host of the change in status.
The daemon works for me (64-bit Wheezy). (Verifying ... yes, it does work.)
