Nope.  There is no difference.  They both should send _exactly_ the same
USB byte stream to the usb8388.  If they do not, there is a bug.
Unfortunately nobody at Marvell who actually _has_ documentation on how
to flash for the active antenna and later boot2 firmware changes (if
any) volunteered that information or tried to fix the tool, to my
knowledge.  I didn't have active antenna hardware myself, and therefore
I can't risk bricking the _only_ usb8388 I have with random firmware
that wasn't intended for my part.  I'm happy to test this out and try to
get the userspace tool working again if given:

1) one or more active antenna modules to potentially brick
2) documentation on what exactly has changed (if anything) between boot2
3107 and the active antenna boot2 firmware
