Differentiate between input devices - VB.net

[noonan59]

If I have 2 different input devices (such as a barcode reader and a keypad) connected via 2 USB ports, is there a way for a desktop application in VB.net to tell which device is inputting data at any given moment? Currently the program I am working on accepts the input from either device, but it doesn't know which device is producing the input. I need to have one set of code run if the input is from the barcode reader and another set of code run if the input is from the keypad.

thanks.... Dan

So would they if they handed a card to someone
besides its made for that.
Sanitary wipes are the trick.
