Hi, I don't think there's particularly a right version to use, the backend hasn't been touched in years. Although, the parport_pc has been slightly broken for quite a while: http://bugzilla.kernel.org/show_bug.cgi?id=7491 That might explain what you're seeing? Is the I/O port displayed the same when you don't have ppdev loaded? If not, er.. try messing with the bios settings so the port matches what parport_pc assumes? Sorry it's not a great solution.. and sorry for the slow reply. Cheers, - Matthew Duggan
