Is there any way of USB communication calling DLL directly.

Hello everyone.

I'm software engineer and try to write a program to control power supply unit Keysight E36106A supporting USBTMC communication.
That unit have no GPIB terminal.

Is there any way USB communication like GPIB communication calling API from DLL(gpib-32.dll).
Namely, not to use NI-Visa class, and the way of calling directly API function from DLL to control power supply.

I installed NI-Visa 17.5.

Thank you for your cooperation.

I'm very sorry that seems strange thing written from my misunderstanding.

What I want to do was call API function from DLL for control USB devices.
That was achieved by use visa32.dll with refer to some sample source and technical resource at NI website.

Thank you everyone.

Mizuta.
