New Revision: 3330

URL: http://svn.debian.org/wsvn/pcsclite/?sc=1&rev=3330
Log:
IFDHSetProtocolParameters(): add a hack to support the bogus OpenGPG
card. The card declares a BWI=4 (1.4s) but, sometimes, do not send a WTX
(time request) in time and the on board key generation then fails. The
patch uses BWI=7 (11s)

Thanks to Jan Suhr for helping tracking the bug
