Using a resolution of 2us rather than 10us means that the resolution
(and amount of work necessary for decoding a given signal) is about 25x
higher than in the windows driver (which uses a 50us resolution IIRC)...

Most of it is mitigated by using RLE (which I don't think the windows
driver uses....again...IIRC), but it still seems unnecessary for the
general case.

Wouldn't it be possible to only use the high-res mode when carrier
reports are actually enabled?

(Yes, I know this patch was sent a long time ago)
