I've opened usb_10c.pcb with geda's pcb program, and see only several DIP parts lined up side-by-side, but no traces (bottom or top layer) nor any other indications of PC board artwork (outline, mounting holes, components, etc.) The schematic usb_10c.sch seems to be OK when opened with gschem, and usb_10c.pcb opens without error messages using pcb and I can export gerber files without error messages, but the layout doesn't seem normal (and looking at the gerbers with online gerber viewer just confirms what pcb is showing.)

Am I doing something wrong (maybe using the wrong tool?)

Thanks very much for any advice or pointers (or if there's some way to contact the author ka6sox, that would be great too.)

Thanks again,

Dave
