* Development tree of that driver will be on:

*
* GNU Radio plugin "gr-kernel" for device usage will be on:

*
* TODO:
* Help is very highly welcome for these + all the others you could imagine:
* - split USB ADC interface and RF tuner to own drivers (msi2500 and msi001)
* - move controls to V4L2 API
* - use libv4l2 for stream format conversions
* - gr-kernel: switch to v4l2_mmap (current read eats a lot of cpu)
* - SDRSharp support
