usb to parallel port converter

[Turd]

I just bought a usb to parallel port converter. How do I use it with FB?
In /dev it makes "usblp0" and in /dev/usb it makes "lp0".
I can't just use:

Code: Select all

dim as ubyte a_number
a_number = 255
out 888, a_number

When I try using "open pipe" it says "cat: /dev/usblp0: Device or resource busy"

Using Ubuntu 8.10
