You have the pcscd running.  "/etc/init.d/pcscd stop" will help.
Disable pcscd unless you need it for other applications.

/usr/local/lib/gnupg/pcsc-wrapper has a problem.  Might be a problem
withy libpcsc.  Would need debugging (kill scdaemon, run scdaemon
--server under strace -f to see what is going on).

I am pretty sure that stopping pcscd solves your problems.  Also make
sure that the permissions for /proc/bus/usb/xxxx/nnn for your device are
okay (you need write permissions).
