Hi,

I like to have some ideas about the following problem....

I have a usb connected instrument which have the data. I have to send a signal to the instrument ( some HEX message) and then it will send me the acknowledgement. After receiving the acknowledgement, if I send a specific instruction then it will send me the data which I have to read and show in a different formats.

Can anybody give me an example how to communicate via USB?

Thanks in advance.

The project have to run in windows OS.
