Assigning USB ports to specific programs?

Here is my situation -
I have 2 USB scanners - checkout style scanners, you pass a barcode across it, and it acts as a usb keyboard and enters the barcode data onto the screen, whatever program you have open (excel, notepad etc).
I want to utilise both these scanners, but purchasing 2 separate PCs to do this job is very expensive, especially when essentially all each PC is doing is running a small data entry program and isn't used for anything else.

In my head, this is how I want it to work-

USB Scanner 1, plugged into USB Port 1, is assigned to Program1.exe. Whenever someone scans with usb scanner 1, the data is entered directly into program1, regardless of whats open at the time.

USB Scanner 2, plugged into USB Port 2, is assigned to Program2.exe. Whenever someone scans with usb scanner 2, the data is entered directly into program2, regardless of whats open at the time.

This way, i'd be able to leave two attached to one computer, and two workers could go about their routine without having to wait for each other to finish before scanning, or risking overwriting each other.

Please, someone tell me this is possible!
