Can I interface directly to a USB port from LabView?

[BRW]

I need to communicate with a USB based PIC micro card from a LabVIEW VI. Looking for any experiences as the documentation and resources aren't helping.

Hi,

if the OS set a COM port to the USB device you can use the serail port vi's
c to communicate over USB ports. I tried with modems an it works, but I
don't know with other devices.

The following link has an answer to your question.

Can I Use Third-Party USB or IEEE 1394 (FireWire) Devices with LabVIEW?

Using a USB-serial converter to control your serial instrument should work. The port name (eg. "COM2") should show up in the Device Manager (if you're using Windows). You can then use the regular LabVIEW VIs to control serial ports (either VISA-Serial or the Serial compatibility VIs).
