I was worried that a serial mode bug had crept into the program, so I just
tested the current owfs version with a pl2303 and serial adapter on x-64
architecture (i.e. a desktop system). It works perfectly, both for the
DS9097U and the passive adapter.
So assuming your USB/serial adpter and DS9097U are fine, the problem is
with the two different architectures. Could there be bugs in the ARM
version of the pl2303 kernel module?
I'm not exactly how to procede, except that maybe trying another program
(like digitemp) for comparison might be illuminating.
