A notable difference between the built-in CCID driver and pcscd is probably the user credentials that open the USB device. Make sure you have write access to the character device in /dev/bus/usb that corresponds to your smartcard: $ lsusb [...] Bus 001 Device 006: ID 04e6:e003 SCM Microsystems, Inc. SPR532 PinPad SmartCard Reader [...] $ ll /dev/bus/usb/001/006 crw-rw-r--+ 1 root root 189, 5 Mar 13 15:55 /dev/bus/usb/001/006 $ getfacl /dev/bus/usb/001/006 getfacl: Removing leading '/' from absolute path names # file: dev/bus/usb/001/006 # owner: root # group: root user::rw- user:peter:rw- group::rw- mask::rw- other::r-- Also, if I were you, I'd clean the smartcard contacts with isopropyl alcohol. I'm not sure what other cleaning agents would work well, I just use that one. It could be that your card has just died. Smartcards are not the most robust devices, and they are subjected to stress usually. HTH, Peter. PS: I'm not 100% sure that libusb opens that particular character device... I believe it's the correct one, but wouldn't swear on it. -- I use the GNU Privacy Guard (GnuPG) in combination with Enigmail. You can send me encrypted mail if you want some privacy.
