MFC r270134:
Use the "bSubslotSize" and "bSubFrameSize" fields to obtain the actual
sample size. According to the USB audio frame format specification
from USB.org, the value in the "bBitResolution" field can be less than
the actual sample size, depending on the actual hardware, and should
not be used for this computation.
