Well, I don't find my webcam cable too long, but I have pretty old machine with no generic USB 2.0 support, so I use PCI USB card... It may have something to do with that... And I've freed as much USB connections I could, but I still get the same error... I'll try to change USB card... don't think it'll help, but... hey... At least I'm going to change something... =D
