Problems with USB interrupt

Hi.
I'm currently working on a project involving a custom made USB device. I was planning to use the USB RAW class to communicate with it. The problem is that VISA can't seem to find the interrupt endpoint of the device. This works just fine with a bulk endpoint. Any good tips?

Yes. Please upgrade to NI-VISA 3.1, now available at www.ni.com/downloads

We fixed several USB bugs, including:
1) interrupt endpoints
2) interrupt events
3) unplug/replug - your VISA session will now return VI_ERROR_CONN_LOST if the device is disconnected and will work when you plug it back in, no need to close and re-open the session!
