-  TTUSB_HWSECTIONS:
-    the DSP supports filtering in hardware, however, since the "muxstream"
-    is a bit braindead (no matching channel masks or no matching filter mask),
-    we won't support this - yet. it doesn't event support negative filters,
-    so the best way is maybe to keep TTUSB_HWSECTIONS undef'd and just
-    parse TS data. USB bandwidth will be a problem when having large
-    datastreams, especially for dvb-net, but hey, that's not my problem.
-
-  TTUSB_DISEQC, TTUSB_TONE:
-    let the STC do the diseqc/tone stuff. this isn't supported at least with
-    my TTUSB, so let it undef'd unless you want to implement another
-    frontend. never tested.
-
-  debug:
-    define it to > 3 for really hardcore debugging. you probably don't want
-    this unless the device doesn't load at all. > 2 for bandwidth statistics.
