I've tested it under Windows 2000 and XP guests and also with Ubuntu Feisty and Gutsy with exactly the same error. When trying to enroll fingerprints, the device starts the scan but ""locks"" and the fingerprint scan fails. I tried also on a Windows box, same device and software of my guest machine, and it works fine. I'm not sure how to debug this and I've never had specific hardware problems, so I need some help with this. Thanks, Guilherme " defect closed other VirtualBox 1.4.0 obsolete other other
