I am trying to get nrComm to work with a WinUSB device.

In device manager the usb device service is listed as WINUSB but when I try
to use nrComm it says that the device service is NULL.

Is this a trail limitation or can it only work with the nrUSBDriver?

nrComm Lib uses WinUSB driver or nrusb driver for I/O operations with usb devices.

But using the trail version I can't connect to usb devices using winusb.

The test programs always say I need to install winusb or nrusbdriver.
