Trying to debug this further resulted in the following preliminary
analysis:
In function HPRescanUsbBus():
parent = udev_device_get_devnode(parent);
udev_device_get_devnode() returns NULL (which is possible, according to
http://www.kernel.org/pub/linux/utils/kernel/hotplug/libudev/libudev-udev-device.html#udev-device-get-devnode),
but pcscd uses this result unverified later in a strdup().
I'm not really sure what kind of device node you are trying to resolve
here. I've tried to debug it further, but I don't really know what
you attempt to resolve here. udev_device_get_syspath(parent) works,
but it is not what the CCID driver wants as input.
Regards,
Harald
