[Hackrf-dev] using hackrf with the raspberry Pi 2

[Paul Connolly]

2MSPS is the lowest samplerate that the HackRF, realistically supports
without aliases, because the smallest bandpass filter in the MAX2837 is
1.75MHz.

The USB in all RPi hardware is known to be problematic for anything
requiring high throughput.
