I've already purged pcsc with aptitude. And I still get the same messages:

(Logging with option debug-level advanced and debug-ccid-driver)

Well instead of a broken pipe, I get a premature EOF...

Uhh. I'll read how strace works, and I'll come back to you.

Visibly, purging pcscd does not solve the problem. Concerning
permissions, I guess I have some work to do:
