Hi, I fear that that the backtrace will be rather disappointing, as the gdb doesn't find any symbols for the pcscd-binary. Now the odd thing is, if you start the gdb if you then remove the card-reader for the first time, it doesn't crash. It is only the second time when the read is removed that the application crashes. As there are no symbols, you get only the addresses in the backtrace. If the gdb starts its notifies me that already another instance of pcscd is running.
If you look at the green led of the reader, it goes out just before ubuntu-login-screen pops up. If you remove the reader and plug the reader back in, the green led goes on for a second or two and then goes back out. ** Attachment added: "LogGdbVascoReader.txt" https://bugs.launchpad.net/ubuntu/+source/pcsc-lite/+bug/1366152/+attachment/4197264/+files/LogGdbVascoReader.txt -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pcsc-lite in Ubuntu. https://bugs.launchpad.net/bugs/1366152 Title: System crash when Vasco-card-reader is plugged in at powerup Status in “pcsc-lite” package in Ubuntu: New Bug description: I'm using VASCO Data Security International Digipass 905 SmartCard Reader which is working fine. However if the device is plugged in at power-up, the device isn't handled well. Although the device is in the ilisted usb-devices, pcsc-scan doesn't find the device at all (Which is normal as the green-led is going out after the kernel starts). If one tries to remove the card-reader, a system-crash happens. After that the pcscd-service seems to be halted : pcsc_scan PC/SC device scanner V 1.4.22 (c) 2001-2011, Ludovic Rousseau <ludovic.rouss...@free.fr> Compiled with PC/SC lite version: 1.8.10 SCardEstablishContext: Service not available. One can recover from this problem by 1. Unplugging the reader 2. Manually starting the service again by sudo service pcscd start 3. Plugging back the reader in (green led stays on, red led goes on when a card is put in) The bug is not related to a 64-bit architecture as it happens also with 32-bit machines.
