I am not sure how well parallel port contention is handled in Linux. I
am not aware of our parallel port pass-through even working in Linux.
You have proven that it does, somewhat, seem to work. As far as being
able to change anything with the Backpack driver to get this to work
better, I don't forsee any changes. We supply a driver that works with
the Backpack on the parallel port. Your other option is to add a second
parallel port and split the devices, or you could use the Backpack on
USB since we do have a USB firmware loader on our Web site.
