--
Capture the enumeration of a device having at least one isochronous endpoint,
such as a USB camera.
Examine the ENDPOINT descriptor in the "GET DESCRIPTOR response CONFIGURATION"
frame. A bmAttributes value such a 0x05, which should display a
Synchronisationtype of "Asynchronous", instead displays "Unknown".

The numeric value_strings for the 'sync' and 'behaviour' fields were coded as
byte-relative constants instead of field-relative constants.
