This question needs to be re-stated with a lot more information.
As of right now you've picked a few words from the middle of a conversation and put them in a post.
What is the device in question?
What is it's method of communication with the computer? rs232? usb? ethernet? firewire? isabus? magic?
What class are you looking for? Do you have some third party software that is supposed to communicate with the device?
Is this a windows or a web-based application?
