LabVIEW VISA USB driver: Known issue with LV 6.1 & LV 7.0 version?

[boucan_canot974]

Hi,
I am going to develop VIs based on the LabVIEW USB driver. I would like to know if there are known issues with both versions of LV6.1 & LV 7.0 VISA USB drivers.
If yes, where can I find a detailled list of those issues?
Which driver will it be better to use and why?

Regards,
Pascal.

Pascal:

Well, we introduced USB support in NI-VISA 3.0, which shipped with LabVIEW 7.0. It will also work with LabVIEW 6x, but it's the same NI-VISA driver. So it's not really a question of "which driver is better".

As far as known bugs, there are 2 that I'm aware of, and we've fixed them in a soon-to-be released NI-VISA 3.1. I don't have an exact date, but if you need more information, let me know. The bugs are:
1) The VI_EVENT_USB_INTR event attributes did not work properly.
2) If you unplugged a VISA USB device and plugged it back in, NI-VISA could not access the device properly.

I hope this helps.
