First link seems to be broken. And i did read the second post. Im very much new to the USB3 driver hardware interaction. So my confidence in being able to properly write a USB3 driver for linux isnt high even if a wrapper is already provided. Thats the reason for this post, to see if something is already out there that can just be plugged in to nearly replace the CyUSB C# DLL . In software terms something that has similar Interface even if its in C++.
You can ignore the first link since both the links talks about similar context.
We have provided all available resources in the FX3 SDK for Linux. We do not have any additional resources as you asked for.
Please refer source code of example host applications provided with the SDK. This may help you.
