Hi,

I'm trying to read data from a usb device that emulates as a keyboard (its a magnetic card reader).
Do you know how I should get going. 
here are some question that i have...
1) As the process would be working in the background how do i make sure that the input that this usb emulated keyboard is inputting to this process. usually you have the terminal selected and just read from stdin.
