Hi all, I'm using an USB keyboard with SC reader incorporated. The computer
seems to slowdown and always I connect two SC readers to the computer the
system freeze. I got the same behaviour randomly when I use an only one SC
reader and launch a print job to the USB printer.
Doing a 'strace' to the pcscd process I get some timeouts (also tried to
increase time of polling to 1,5 seconds):

I've got a Linux 2.6.19 system (I've also tried 2.6.33 and 2.6.34 with same
problem), libusb version 0.1, pcscd version 1.4.2 (also tried with other
versions) and driver libccid version 1.3.1 (also tried with 1.3.4).
All suggestions will be appreciated.
Thanks.
