The Microtek models have several operating modes, for example flatbed, TMA
and automatic document feeder. The TMA mode is used for dedicated
transparency adapters (for example, when you replace the lid of the
scanner by a lid with a builtin lamp), not for this 35mm-adapter.

They also have modes for stripes and slides. When this obscure adapter
came out I thought that the stripe and slide modes could have something
to do with this adapter and invented this lightlid-35 option. Obviously
this is not case.

Normally the attributes of these different modes (for example
the scan area sizes or the data formats between these modes might be
different) can be inquired. But on my own X6 I tried to
inquire the attributes of all possible modes, i.e. all bit combinations,
that could represent such a mode - even the reserved ones - and got
only errors.

Moreover, it is normally possible to determine during runtime whether
a (real) TMA is actually connected to the device. This isn't possible, too,
for this 35mm-adapter. From the backend's point of view this device is
simply not present, whether it is connected or not.

To state it clearly: This 35mm-adapter has nothing to do with the TMA
option of the backend.

Thus all you can do is to put it onto the glass of the scanner and start
a scan from the flatbed...

Considering my own observations this behaviour is consistent with the
behaviour under Windows, but maybe there are models that behave different.
