heres what he says in the thread

The device uses buffering, which allows you to eliminate delays associated with the fact that USB access is not in real time. The use of buffering has a disadvantage - reading the inputs does not occur at the same time as controlling the outputs. Therefore, it is impossible to use certain commands with this device, where the state of outputs at a given moment depends exactly on the state of inputs at that moment. However, in many LinuxCNC applications, this feature does not bother at all, for example in the construction of simple CNC plotters / milling machines, laser engraving machines or plasma cutters.
Buffering also has advantages - it reduces jitter.
