Я так понял, что по bcdDevice, который сообщает USB device и полю bcdDevice, содержащемуся в конце загрузочного файла (suffix) можно различать релизы.
The bcdDevice field may contain FFFFh, or it may contain a BCD number. If it contains FFFFh, it is
ignored. If it contains a BCD number, then that number should represent the version of firmware
contained in the file. This field is for informational purposes only and does not restrict whether the file
may or may not be sent to a device. One possible use of this field is to notify the operator when a
download will result in sending a lower firmware version number to the device than the version number
that is currently reported by the device. Therefore, it is suggested, but not required, that vendors use
this field to record a firmware version number that increases with each revision of firmware.
