Correction: It is pcsc-lite-openct-0.6.14-1.fc7 that trigs the problem, not openct. It doesn't matter if openct service has been started or not and ctapi-cyberjack-pcsc causes the same ... In that case, sounds like it's a problem with pcsc-lite, not openct. FWIW, I cannot reproduce, works fine for me with pcsc-lite-openct-0.6.14-1.fc7.x86_64, pcsc-lite-1.3.3-1.fc7.x86_64, Aladdin eToken PRO. Yes, it is probably a pcsc-lite problem then. Can I provide anything to help identify why it happens on my system only? strace? gdb? debug flags? Same problem on "F8" pcsc-lite-1.3.3-1.fc8 pcsc-lite-openct-0.6.14-3.fc8 I have the same problem on Fedora 8, fresh install. I have an Aladdin USB eToken, but I haven't tried plugging it in yet. The following shows up in /var/log/messages. messages:Nov 10 00:28:05 localhost pcscd: winscard.c:219:SCardConnect() Reader E-Gate 0 0 Not Found messages:Nov 10 00:28:05 localhost pcscd:last message repeated 4 times messages:Nov 10 08:54:58 localhost pcscd: hotplug_libusb.c:394:HPEstablishUSBNotifications() Driver openct-ifd.bundle does not support IFD_GENERATE_HOTPLUG However, when I do the following /usr/sbin/lsof |grep pcscd I notice that the following lines keep showing up (each line from a separate execution of the above command). pcscd 8783 root 6r unknown /proc/bus/usb/006 (stat: No such file or directory) pcscd 8783 root 6 REG 0,17 52 282 /proc/bus/usb/005 lstat: No such file or directory) pcscd 8783 root 6u unknown /proc/8783/fd/6 (readlink: No such file or directory) pcscd 8783 root 6 DIR 0,17 0 251 /proc/bus/usb/004 lstat: No such file or directory) So, does this mean that pcscd is polling for a USB device to be attached? Is it looking for "Reader E-Gate"? I have exactly the same problem. pcscd works but uses 100% cpu. Fresh instalation Fedora 8 pcsc-lite-openct-0.6.14-3.fc8 pcsc-lite-libs-1.3.3-1.fc8 pcsc-lite-doc-1.3.3-1.fc8 pcsc-lite-devel-1.3.3-1.fc8 openct-0.6.14-3.fc8 Nov 19 18:19:08 home pcscd: pcscdaemon.c:533:main() pcsc-lite 1.3.3 daemon ready. Nov 19 18:19:08 home pcscd: hotplug_libusb.c:394:HPEstablishUSBNotifications() Driver ifd-cyberjack.bundle does not support IFD_GENERATE_HOTPLUG Ah, We've added a new ifd which doesn't support IFD_GENERATE_HOTPLUG. There is an already known bug the pcsc-lite goes to 100% cpu when old IFD's that don't support hotplug are added. We need a bug against ifd-cypberjack.bundle to get it to support IFD_GENERATE_HOTPLUG if we are to make it install by default. (the pcsc-lite issue also needs to be fixed as well). Just to confirm: I see this issue on Fedora 8 as well, removing the packages mentioned in comment 1 and comment 2 "fixes" the problem: pcsc-lite-openct ctapi-cyberjack-pcsc Luckily we have no need for these two packages (yet). Is bug 374291 related by the way? *** Bug 374291 has been marked as a duplicate of this bug. *** Just a note: I didn't see any smartcard related services eating my CPU when I booted a freshly installed fedora 9, so it seems to be fixed in F9. I can confirm that the reported problem seems to be fixed in Fedora 9. I however not tested if pcsc-lite actually works. |
