I bought a CHERRY SmartTerminal ST-1044. I installed both the API from the "software" directory on the CD that came with it, along with the driver off their website. The driver was labeled "MacOS CCID, PC/SC driver V3.1.0.2 - Release: 02/14/2012 - 175 kB - MacOS X 10.5.x, 10.6.x and 10.7.x on Intel". FWIW, I'm on MacOS X 10.8. The device shows up in "about this mac" as "SmartTerminal XX44". When I insert a card, the green light briefly blinks red and goes back to green. In system console, I see "5/19/13 10:37:38.487 AM com.apple.SecurityServer[19]: token in reader Cherry SmartTerminal XX44 00 00 cannot be used (error 229)" Really, all I want to do is read all the bytes out of a smart card and be able to modify arbitrary bytes. I'd be very happy if the device showed up as a block device in /Volumes or something. I've tried installing some other software, such as from http://smartcardservices.macosforge.org/trac/browser/trunk/Tokend/PKCS11and http://www.gemalto.com/products/dotnet_card/resources/libraries.html So I'm just stabbing in the dark and probably making the situation worse. :) Anyone out there have any recommendations? Thanks, Douglas
