virtual key press of an external usb device



Dear champs,
 
There is an USB device which has a keypad with 10 keys. During the testing of device, the keys has to be pressed and for every keypress there will be some actions involved.
The idea was to automate the key press without any manual intervention. I hope some hardware will help in achieving the key press action. I mean some DAQ (example) hardware will simulate some signals that will be equivalent to the key press.
Does my query makes sense. Please throw some lights.
Thanks for ur patience.Mathan
