ANSWER
I have contacted PoLabs/PoScope and they told me the following information:
As I previously stated, I was able to input new commands for a single bit every 2 ms which is slightly better than what PoKeys told me to expect, which is good. Can't wait for the newer driver.
Thanks PoKeys for the quick and accurate response and the support!

PoKeys56U uses standard HID interface and thus relies on system's drivers for communication. Due to USB specifications, communication is limited to approximately 4-5 ms per one data transfer.

In addition - you may have noticed that with the newer firmware updates, Windows asks for a driver for PoKeys - we are working on a faster communication interface that should be available in April. That will allow 1 ms command execution.
