Hmmm, very interesting. I'm using an OMNIKEY 6121 USB card reader, which I purchased along with my OpenGPG-compatible card. Since the retailer where I bought it ( offers quite a few card readers, I even made sure to contact them about which reader I should choose beforehand, so that I wouldn't end up with anything that was incompatible... Also, I just made sure to check out their website once again to have another look at the reader's specs, however unfortunately I wasn't able to find anything OpenPGP-specific on there...
