I have developed a software for managing the details of patients, the software stores the data into MSsql database.... However, the data I need to get stored has to be read from an external device which transmits data... Now my query is how I can read that data using VB.NET 2010.

I have searched on net and found that I can use My.Computer.Port to read data from USB connected device, but I am unable to get its logic and any example to get this practically done...

I also been through many books to understand the practical way of doing this, but not yet resolved with anything.....

If somebody can help me with an example so that i get a way forward to accomplish my task....
