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.
