[MacRuby-devel] CNC Machine control using USB to IEEE 1284 Parallel port adapter

[Robert Rice]

Hi Scott,

I don't see any change in the /dev directory when I plug and unplug the device.

Unfortunately, Apple hasn't updated the USB example developer projects and many of the examples don't work under Lion.
I may need to use IOKit routines to search for the device in the USB device tree.

Thanks,
Bob Rice
