Older versions of Sound Devices and Edirol drivers were buggy and
didn't quite comply. The latest USBPre driver seems to be doing a
better job, but still needs quite a bit of love in other areas. Edirol
used to crash when certain properties were requested. AMS used to read
the low range and ignore the high range value, which was apparent in
the USBPre driver which (correctly) reported an output range of [5k,
55k]. To appear correct in AMS, it was changed to report several
ranges: [32k, 32k], [44.1k, 44.1k], [48k, 48k]. All of this is from
memory; honestly I haven't mucked with it for several months... since
AMS became part of Panther, I eliminated my pref's tab that previously
performed those duties in 10.1/10.2.
