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. > 2010/2/19 Douglas E.
