True, but converting to dvb-usb-v2, is more complex. In particular,
dib0700 and dib3000 drivers rely on some things that may not be ported
to dvb-usb-v2.

So, I don't think we should do such change during the -rc cycle.
Also, such change requires testing. So, one with those hardware should
help with it, or the developer willing to do the conversion would
need to get those old hardware in hands.

Thanks,
Mauro
