[Linux-parport] usb parport as gpio

[Sebastian Kuzminsky]

Hi folks, I need a couple of digital I/O lines for a project, and back in
the bad old days I'd have just used a parallel port.  Now I need to go
through a USB port, and it seems to me that USB parallel port adapters
don't provide general-purpose I/O lines like the old-school parallel
ports did.  Is that really true?
