This (coupled with the fact that Windows never seems to suffer this
problem) prompts me to wonder if Windows simply never uses the cache
syncronisation feature and indeed if any umass devices actually require it
to be used. Disabling it seems to be by far the most common quirk entry.
Might we get more reliable umass behaviour by making not using it the
default ?
