Tk USB Library (Tk_USBLib.dll)

Goal

The goal with this project is to create one or several "easy to use" DotNet DLL's for communication with USB Devices.

Current status

2020-12-01

• The Event Listener is now using Win32_PnPEntity to sence device insertion/removal.
• The existing Device Info class (USBDevices) replaced with two other classes. One using Win32_PnPEntity, another using Win32_USBHub.
• A new Deveice Device info class (USBDevices) class created, merging data from Win32_PnPEntity and Win32_USBHub.
• An interface for the two Device Info classes is added.
• The Device Info function GetAllProperties() deleted.
• Project version numbering implemented.

2020-11-29 (Initial version)

• Reading information about devices inserted.
• Trigging an event when devces are inserted or removed.
