I emerged pcsc-lite and then got the drivers for the Reader from acs web page, here: http://acs.com.hk/DriversManual.asp?PID=53 acs provides some Makefile that puts reader's driver in /usr/local/pcsc/drivers, however pcscd seems to read it from /usr/lib/readers/usb, so I copied the files and tried again. With every file in its directory I started the init script, but it didn't seem to recognize the reader. Then I tried to run pcscd manually redirecting the debug info to standard output and got this: /usr/sbin/pcscd -f -dstdout pcscdaemon.c:251 main: pcscd set to foreground pcscdaemon.c:265 main: debug messages to stdout pcscdaemon.c:445 main: pcsc-lite daemon ready. hotplug_libusb.c:344 Adding USB device: 003:015 readerfactory.c:1391 RFInitializeReader: Attempting startup of ACS ACR 30u 0 0. readerfactory.c:1133 RFBindFunctions: Loading IFD Handler 2.0 eventhandler.c:180 EHSpawnEventHandler: Initial Check Failed on ACS ACR 30u 0 0 Apparently pcscd detects a reader being plugged in but fails to perform some initial check.

i dont think many people in Gentoo have experience with this library let alone they also have the hardware you do, so you'll probably have to take this upstream to get it resolved: http://pcsclite.alioth.debian.org/
