I'm trying to use USB communication in VISA for the first time.
I have implemented the VISA driver using the VISA device driver wizard, and it seems to be up and running. The USB device is recognized by MAX.
My problem is getting a simple data exchange to run in VISA. I am trying to send a request to get the device descriptor from the device.
I used the VISA USB control out vi for this with request type set to ' 0 ' and request as ' 6 ' (obtained from USB specification).
When I run this vi , VISA USB control out returns an error code of " -1073807299". I am not sure what this error code means.
Can someone tell me how to implement this simple exchange in VISA?
Thanks in advance
Siddharth
