You probably meant the SCR 355.

This problem is well known.  When using GnuPG with its internal CCID
driver that version of thye SCR 335 works fine due to a workaround for
the bug.  I developed the whole smart card stuff with such a reader and
thus there should be no problem.  Well, unless you need it for non-GnuPG

Maybe we should come up with an IFD on top of GnuPG'd scdaemon ;-)
