VISA USB Isochronous

[Intaris]

Having recently done some work with VISA USB communication, I was wondering if there are any plans to support Isochronous transfer in VISA?

If so, when should it be available?

If not, why not?  It's an important part of the USB Specification.

Do you mean SPI communication?

Hey Shane,

Isochronous transfer does not guarantee data delivery. Data may be lost during the data transfer. In most scientific and engineering application, this is not a desirable situation. It is primarily used to transfer audio and video.

We did not see a lot of demand to implement it. Of course, we are always open to suggestions. I would recommend you to fill out a product feedback on ni.com/contact.

Song D,

I presently have an application dependent upon using isochronous transfer for USB.  Has there been any progress made in NI VISA support?
