The vendors most probably write their own drivers for windows. They do
not for FreeBSD and its best effort for FreeBSD.  I have yet to come
across a USB umass device that needs a quirks setting to make it work.
But I am sure there are many out there as there are dozens of different
vendors/OEMs out there of all sorts of quality.  Having to deal with the
edge cases using a single command is perfectly acceptable to me. If
setting a quirks value for FreeBSD is not workable for you, perhaps
Windows is a better choice for your use.
