With the new pcsc-lite-1.6.0 and ccid-1.3.13 things are working fine.
I can not reproduce the failures discribed below. libusb.so.1 has not
changed, so I assume some change to pcsc or ccid has fixed the problem!

While doing some smartcard testing on Solaris 10 I ran across two bugs
with the open source pcsc-lite and ccid code as it interacts with the
Solaris libusb.
The first fix was accepted by pcsc-lite, but the second was rejected,
as a problem with libusb, not pcsc-lite or ccid.
I have attached the original messsge with the patches as I know there
has been a lot of interest within Sun with using smart cards, Kerberos
PKINIT, opensc and pcscd and a number of messages on how to get these
to compile on Solaris and Open Solaris.
I would hope that someone within Sun would find this interesting and look
at it closer to see if it is indeed a bug on libusb or not and if it also
fails on Open Solaris. For my testing I can continue to apply the ccid
patch.

Committed in revision 4766.

The crash is not in pcscd but in libusb on Solaris.
libusb should not crash if called on a device that disappeared. libusb
should return an error code instead.
I reject this patch, sorry.
