now I had a coredump. What I have changed: - I installed "normal" Ubuntu libccid (1.4.4) - I used pcscd 1.8.3 but compiled it with: ./configure --enable-usbdropdir=/usr/lib/pcsc/drivers --enable-libusb --disable-libudev (And added some printfs to it) It worked for some time (~3min), and suddenly I had a segfault. log and backtrace appended. regards, Martin 00000050 winscard.c:235:SCardConnect() Attempting Connect to Aladdin eToken PRO USB 72K Java 00 00 using protocol: 3 00015640 hotplug_libusb.c:604:HPRemoveHotPluggable() Removing USB device[0]: 2:69:0 00000055 eventhandler.c:148:EHDestroyEventHandler() Stomping thread. 00000058 ifdhandler.c:401:IFDHGetCapabilities() tag: 0xFB1, usb:0529/0620:libusb-1.0:2:69:0 (lun: 0) 00000050 ifdhandler.c:401:IFDHGetCapabilities() tag: 0xFB2, usb:0529/0620:libusb-1.0:2:69:0 (lun: 0) 00000033 eventhandler.c:173:EHDestroyEventHandler() Request stoping of polling thread 00000033 ifdhandler.c:366:IFDHStopPolling() usb:0529/0620:libusb-1.0:2:69:0 (lun: 0) 00665242 ifdhandler.c:1151:IFDHPowerICC() action: PowerDown, usb:0529/0620:libusb-1.0:2:69:0 (lun: 0) 00000062 ccid_usb.c:620:WriteUSB() write failed (2/69): -4 No such device 00000017 ifdhandler.c:1166:IFDHPowerICC() PowerDown failed 00000015 eventhandler.c:446:EHStatusHandlerThread() powerState: POWER_STATE_UNPOWERED 00000023 eventhandler.c:469:EHStatusHandlerThread() Die 00000065 ccid_usb.c:620:WriteUSB() write failed (2/69): -4 No such device 00000024 ifdwrapper.c:341:IFDStatusICC() Card not transacted: 617 00000041 eventhandler.c:188:EHDestroyEventHandler() Thread stomped. 00000024 readerfactory.c:987:RFUnInitializeReader() Attempting shutdown of Aladdin eToken PRO USB 72K Java 00 00. 00000015 utils.c:68:SendHotplugSignal() Send hotplug signal to pcscd (pid=25727) signal_reload HPReCheckSerialReaders 00000063 hotplug_libusb.c:629:HPReCheckSerialReaders() 00000011 ifdhandler.c:293:IFDHCloseChannel() usb:0529/0620:libusb-1.0:2:69:0 (lun: 0) 00000061 ccid_usb.c:620:WriteUSB() write failed (2/69): -4 No such device 00000061 readerfactory.c:863:RFUnloadReader() Unloading reader driver.
