Package: pcscd
Version: 1.8.15-1
Followup-For: Bug #812087
Dear Maintainer,
I have the same problem with pcscd, and I did not even have to insert a
USB mass storage device, when I plug my notebook into the dock station,
fans go off like mad and pcscd takes on CPU cycles.
This bug is quiet strange.
Alexander, have you tried to generate libusb debug using:
$ sudo LIBUSB_DEBUG=99 /usr/sbin/pcscd -dfa
You may have to downgrade libusb-1.0-0 to version 1.0.19 from stable.
Another idea is to rebuild pcscd with hotplug debug enabled. No need to install
pcscd so you can't break your installation.
1. Get the source code of pcsc-lite, for example from
https://alioth.debian.org/frs/?group_id=30105&release_id=2019#pcsclite-_1.8.15-title-content
2. install the build dependencies using:
$ sudo apt-get build-dep pcscd
3. edit the file PCSC/src/hotplug_libudev.c and change the line 66 from
#undef DEBUG_HOTPLUG
to
#define DEBUG_HOTPLUG
4. configure pcsc-lite using "./configure"
5. run pcscd using:
$ sudo ./src/pcscd -dfa
6. try to reproduce the 100% CPU consumption problem
This may generate a lot of logs if the problem is with libudev.
Bye
