The goal of this small project is to provide open source API library for simple low-cost USB digital I/O modules made by someone named DCT (search on eBay for "USB I/O data acquisition control module for Smart Home" and such).
The advantage of HID-based interface is that no kernel drivers and no simulated COM-ports are needed. It is easy to detect and address the connected devices.
This repository contains only the software for the host, no device-side firmware and board design.
We are not associated with the manufacturer(s) of these devices or author(s) of the original software offered by eBay merchants. The merchants currently provide only API library for Windows, only in binary form. (The web site dcttech.com does not have a registered owner, and the original software does not contain any contact information).
The project home page is on the V-USB wiki, because the firmware of the device is based on V-USB. V-USB enables very simple and low-cost USB hardware solutions.
Use this software on your own risk.
WE DO NOT ASSUME RESPONSIBILITY FOR ANY DAMAGE.
Binary and source downloads are in Releases.
