Udev rules for SCM card reader

Phorize · 10-05-2011, 03:12 AM

Hi All.

I would like to get my SCM spr532 card reader up and running with gpg. I have added the udev rules as described here:

http://wiki.fsfe.org/Card_howtos/Car...tup_%28udev%29

As root user I do:

Code:

gpg --card-status

Everything is fine.

lsusb shows the device:

Code:

Bus 003 Device 002: ID 04e6:e003 SCM Microsystems, Inc. SPR532 PinPad SmartCard Reader

Problem is I can't see the device as a normal user. My normal user is in the scard group. I probably need to tell udev to allow my normal user to use the device.

This was done as normal user:

Code:

bash-4.1$ gpg --card-status
gpg: apdu_open_reader: failed to open driver `libpcsclite.so.1': libpcsclite.so.1: cannot open shared object file: No such file or directory
gpg: card reader not available
gpg: OpenPGP card not available: general error

What do we think?

Best,

Kristian

All udev is doing is setting permissions on the device. It is not a card reader driver. The error message that you got says:

Code:

libpcsclite.so.1: cannot open shared object file: No such file or directory

You are missing the file libpcsclite.so.1. This is a library file which contains the code to talk to the device and actually read the cards.

Thanks for your reply. I'm not sure that you are right that this is a missing library issue; as root user the device functions perfectly. gpg --card-status gives me the right output for the card I have inserted into the reader. This is why I think it could be udev issue.
