What actual errors do you get, and which exact version of libfprint did you test? There are some known bugs in the uru4000 code, but those only happen when you remove your finger as soon as it touched. I have one of those here (a Microsoft variant) and it seems to be working fine. Send us the debug output, and let us know. Cheers _______________________________________________ fprint mailing list [email protected] http://lists.reactivated.net/mailman/listinfo/fprint
