Mac LabView to USB interfacing.

Hi,

I'm developing a program in LabView to communicate with a USB device (Delcom-Cypress USB microcontroller). Has anyone here any experience using LabView with USB devices?

I've found a function in LabView called OutPort the description given is "This is used to copy data values to the system's physical memory within the port I/O range beginning at the address specified." The fuction takes a 16 bit address as an input and up to 32 bits of data to transfer.

When I run the 'USB Prober' utility the USB device is recognised successfully with the description 'Low Speed Device @6 (0x18210000) Composite Device......USB I/O Controller'. Is the hex number here the port address? If that is the case then it's a 32bit address which is too long to be used as the input of the OutPort function?

Any advice would be much appreciated.
Thanks,
Dave.
