How to read from Msr (Magnetic Stripe Reader) directly in HID mode (not keyboard) without its OPOS driver or POS for .NET framework?

I have HP USB MINI MSR (Magnetic Stripe Reader) works by default in HID (Human Interface), and not in HID-KB (Keyboard mode). I need some way to access the data read by the MSR directly without using any additional driver such as OPOS driver or POS for .NET framework! Is there any native and clean way to do开发者_如何学Go that (for example by accessing USB directly).

I need to do that in c#.
