Bug#633852: libacr38u: Some 1.8v and 3.3v smart cards don't reset/start

[Michael De Backer]

Package: libacr38u
Version: 1.7.10-1
Severity: normal
Tags: upstream patch

Hello,

The driver resets the card using RESET_WITH_5_VOLTS_DEFAULT.
Some low voltage smart cards (Ex: Atmel AT88SC**CA family) will fail:
pcscd: eventhandler.c:443:EHStatusHandlerThread() Error powering up card.

If the card is reset with RESET_WITH_SPECIFIC_VOLTAGE - 0x00 (automatic voltage
detection), the card resets properly and the ATR can be read with any card.

This still applies to the new driver (1.7.11).
It is probably a good idea to forward this to upstream.

Regards,

Michael De Backer
