Yes, I use pcscd, but it also occurs with only ctapi drivers. I use a Reiner 
SCT cyberjack ecom (class 3 with display and pinpad). OS is openSUSE 11.1 
32bit. 

One way to try to trigger this odd behaviour was to e.g. sign something, 
remove the card, stop and start again pcscd daemon, or remove the card, or 
stop pcscd daemon and play with onlinebanking (=ctapi), start pcscd again and 
trying to use the openPGPcard again, it always was triggered after the card 
was used and some change happened, be it to remove the card use a totally 
different card, change driver etc.

libusb:
[malte_gell at linux-61r3]5520 20:08~> rpm -qa | grep libusb
libusb-0_1-4-0.1.12-136.10
libusb-devel-0.1.12-136.10
libusbpp-0_1-4-0.1.12-136.10
libusb-1_0-0-0.9.3-4.20

Interesting: I added "card-timeout 0" to scdaemon.conf and the last couple 
hours everything was fine... now I can remove the card, sign something, move 
the card back into the reader and it is readable, maybe found the cure... Is 
card-timeout 0 harmful as the manpage suggests?

Thanx
Malte
