Even better, I believe I might have found the reason for the daemon not being automatically started. From $ man udisks-daemon: DESCRIPTION udisks-daemon provides the org.freedesktop.UDisks service on the system message bus. Users or administrators should never need to start this daemon as it will be automatically started by dbus-daemon(1) whenever an application calls into the org.freedesktop.UDisks service. Obviously, there needs to be an application asking for the "org.freedesktop.UDisks service". On my (and likely your system as well) there is no such application, hence udisks-daemon is not started. I have now simply added the command you suggested $ udisks --enumerate to my .fluxbox/startup which should resolve the issue.

Cardreaders work differently than USB drives and thumbdrives. Try this: With an EXTERNAL cardreader that is UNPLUGGED, insert the SD card, then plug in the cardreader. Does the SD card come up? Either recognized or mounted? Of course, this technique is unsuitable for internal cardreaders. > So I think it is somehow related to the cardreader, but because I > have two of them in the same box and both don't work, there should > be something else. > > How it is implemented in the current Linux systems ? is there a > daemon which checks devices from time to time or is it interrupt > driven or ... ? Check to see if HAL or UDEV are set up. It should be UDEV which replaced HAL. Also, look in /etc. Is there a udev directory? If there is, is there a rules.d directory under it? And if so, what rules are in it? > it shouldn't be much different from the other usb devices I think. But it is. Cardreaders like floppy and CD/DVD drives need to be polled so the system knows when a card is inserted. All the system sees otherwise is the cardreader. Take a look at some automounting utilities that work with cardreaders. Take a look at udisks, but there are others. And as I said before, investigate writing udev rules.
