[SOLVED] plugging in ACR38U device in USB port crashes pcscd

(Mageia 3 RC x86_64 plus all updates)

Plug in ACR38U USB (Belgian) identity card reader, makes pcscd service crash:

Code: Select all

dmesg

Service can not be started again, due to segmentation fault.
When device is plugged out, service pcscd can be started successfully.

Following is installed:

Same experiment in Mageia 2 x86_64 (with all updates) works perfectly well !

SOLVED
Have a look to the bugreport for an alternative ACR38U driver that works perfectly.

Here is some recipe for installing and starting the ACR38U reader for the case of a Belgian identity card, as tried out under Mageia 4.0 and 4.1.
The rationale is

• that the procedure for linux (Mageia) became not so obvious, given the issue above;
• also the difficulty to find a comprehensive overview of the needed steps for this case

.

1) install generic pcsc-related packages, including the alternate acr38u-driver:

Code: Select all

urpmi pcsc-lite pcsc-tools lib64pcsclite1 perl-pcsc-perl acsccid

2) try this out and diagnose:

Code: Select all

pcscd -fd
# or :
systemctl start pcscd.service
# next:
pcsc_scan


Connect the card reader and insert an identity or smart card in order to observe proper detection of both by pcsc_scan. So far the non-specific part.

3) Install Belgian eID ("beid")-specific packages:
a) install beid middleware and get rid of the "bad" acr38u packages that beid-middleware depends on. Package beid-middleware will nicely stay in place...

Code: Select all

urpmi --allow-nodeps beid-middleware
urpme lib64acr38u0 acr38u


b) go to eid.belgium.be → "installing eID software" → linux;
download package eid-archive-epel.rpm, which is the one made for Red-Hat-like linux distributions.
To install this rpm, you might for example open the folder in dolphin or konqueror and right click on the package, selecting "Open with→installer".
Now you're done installing. Configuration of a browser like firefox is more straightforward, I refer you to the eID-website and after that, you should be fully operational.

4) Choose between launching pcscd during boot (a) phase or on the fly (b):
a) persistent:

Code: Select all

systemctl enable pcscd.service pcscd.socket

b) volatile

Code: Select all

systemctl disable pcscd.service pcscd.socket


and in case of 4b), running the daemon on the fly is done with the commands under 2)

Not discussed here is the allowed unix user: root or ordinary users. The try-out was done as root, except for the browser configuration of course.

Enjoy the ride.
