There is a thread in the SUSE forum that might contain some tips for you:
All card readers are not created equal. Perhaps you have a friend with another one you could experiment with. Or, if you have more money than patience, you could go through the Newegg reviews to find one that works reliably with Linux, such as the Sabrient SBT-ICR42B. Look at LQ's HCL, but read carefully because the ratings are subjective (one reviewer gives a unit a "10" rating, and then states: "you will probably have to recompile the kernel").
I have a flash pen that 18 months back most distros could not mount, but now it is no problem. So, you can be certain that if you buy a new reader, the old one will work fine on the next release!
Seriously, USB device handling is not bulletproof. Experience with multiple devices on multiple PCs with multiple distros (Gnome and KDE) will convince you that USB handling could use some polish.
If you don't get some forum help, try another card reader.
