Hello, A new version of pcsc-lite is available [1]. This version uses libhal events instead of polling the USB bus to detect card readers insertion/removal. pcscd will then consume zero CPU cycle when no reader is connected. powertop [2] should be more happy.
pcsc-lite-1.4.100: Ludovic Rousseau 23 March 2008 - add libhal support to avoid polling the USB bus. libusb is still supported but libhal is now the default - improve performances in SCardConnect(), SCardReconnect(), SCardDisconnect(). Thanks to Sean Wykes for the patch - SCardListReaders(): returns SCARD_E_NO_READERS_AVAILABLE when no reader are available. Thanks to Thomas Harning for the bug report - add support of TAG_IFD_POLLING_THREAD to use an asynchronous card movements detection instead of an active polling. The reader driver need to support TAG_IFD_POLLING_THREAD to use this feature - CardCheckDaemonAvailability(): lower the priority of the log message in case of "PCSC Not Running" or "PCSC restarted" so that nothing is logged by default. PCSCLITE_DEBUG can be defined to see the message. Programs linked with libpcsclite will not display anything if pcscd is not running. Solves Red Hat bug 428299. - default log level is PCSC_LOG_CRITICAL+1 so that NO log is sent to stderr by default. You need to explicitly set PCSCLITE_DEBUG to have logs. (in a library stderr(2) can be any file opened with fd=2 so should not be used) - ifdhandler-3.tex: more details about deviceName argument of IFDHCreateChannelByName() - some other minor improvements and bug corrections Regards, [1] https://alioth.debian.org/frs/?group_id=30105&release_id=1149 [2] http://www.lesswatts.org/projects/powertop/ -- Dr. Ludovic Rousseau _______________________________________________ Muscle mailing list Muscle@lists.musclecard.com http://lists.drizzle.com/mailman/listinfo/muscle
