Hi,

Is this some kind of cheap clone, hence Prolofic is spelled wrong?

You can try using "usbdump -i usbusX -f Y -s 65536" to figure out all 
the USB activity.

Else there are two printer port devices:

/dev/ulptX

and

/dev/unlptX

Did you try both?

Can you show a USB dump while opening these devices. What host 
controller is this device connected through?

--HPS
