Can i interface a cypress SX2 USB-2 chip to Labview using isochronous transfers?

Hi,

  using VISA, it only supports Bulk, Control and Interrupt, not Isochronous.

Check out section 3.2 on the USB Raw class here :

and there's some more information here :

Using NI-Device however, you could link to a NET2280 PCI-USB 2.0 High speed peripheral controller and get the isochronous capability. Please have a look at the following link for more information :

Obviously the NI-Device is an orderable item; currently the Plus version is about £3555

You'd need to write your own DLL in something other than LabVIEW and then you could call that from LabVIEW.

Hope that helps
