Sure, it is the reader I used for many years.  I am currently using a
3310 or so.

Is there a chance that you can test it on a Linux box?  It looks pretty
much like an USB stack problem or a problem with libusb.  If I find the
time I can test it on kfreebsd 8.2.

You may also install pcscd and use disable-ccid-driver in scdaemon.conf
to check a different CCID implementation.
