You do not need any drivers to use PoKeys56U. It is USB HID device and drivers are in your operating system. However we are preapring some Linux examples, but we do not have any ETA. My opinion is that they should be avaiable in few months.
There are two plugins: - made by Scott and Art. The file is on www.poscope.com - made by Brian - There is a link on www.poscope.com You can use both. Newer PoKeys56U are compatible with PoKeys55, so you can use both with both plugins.
