"Search ROM" is a costly operation on most host adapters (with the
noteable execption of the DS9490, which handles it semi-automatically)
so owfs doesn't do that automatically. You have to read /uncached to
have owfs update it's view on the bus. That's the reason why there is a
node "present" in each device directory. You can check whether a device
is still there without having to "Search ROM" by reading that node (in
"uncached" of course).
Kind regards
