Hi Priyank, two things to consider: For me "hearing aid" implies to increase the volume of a audio signal. But you cannot process signals, which do not arrive at the A/D-converter. The cheap USB-Audio-Dongles have a no stereo mic inout. It is only mono (or in other words: All USB-dongles I looked for, have a mono input...I didnt find any dongle with a stereo input). A hearing aid which feeds the same signal to both ears (mono) will destroy the human ability to locate sounds. While crossing over roads (for example) without being able to locate a sound could be fatal... ;) Furthermore it may be possible, that the input amplifier of such dongles isn't powerful enough to amplify a mic's signal. May be the advertising of such dongles confuses "Line In" with "Mic In" for obvious reasons.
