I never saw problems with this fall back. > BTW, is there anything important to look for when buying such a reader ? > I see in this thread, that there are devices with builtin disk and some > without ... That's the real problem - getting a vendor to honour umass specification should be enough, but in reality many vendors fail on this thing :( Many devices should work just out of the box, but you better have the option to return it to your dealer just in case. -- B.Walter BWCT http://www.bwct.de ticso@bwct.de info@bwct.de
