Hi Brian,
It looks like you have run into a language problem. The Direct show driver for USB cameras returns language specific strings for certain functions. Apparently on non-English OS's, the driver returns the capture pin string in the OS language, so the english string isn't found. We are currently working on a solution for non-English version, but I don't have a definite date to when that will be released. The driver does work on the English version of XP, so this is your best current solution. Let me know if you have any further questions.
Regards
Meister, NIDK
