Hello Paul,
I just installed digitemp on this sheevaplug
There is, I think a strange behaviour with PL2303:
1. I plug the usb adapter. Correctly detected by kernet in ttyUSB0
2. digitemp_DS9097U -s /dev/ttyUSB0 -w -v gives correct 1-wire detection
3. i I redo again digitemp_DS9097U -s /dev/ttyUSB0 -w -v, I obtain:
DigiTemp v3.5.0 Copyright 1996-2007 by Brian C. Lane

I have to unplug the usb adapter and put it in again to have digitemp
working (once)
dmesg gives:

aie aie aie... I'm restarting a complex problem out of my knowledge....
After trying getting OWFS working on my synology and now on my sheeva I
wonder how to manage finnaly...
Any idea of good serial-usb stable adapter I can buy ?

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.

same kind of results if I launch owserver -d /dev/ttyUSB0 etc...
Very strange because it worked the first time, but now, this is
not working anymore. I also tried to reboot the plug.
Don't know really what to do. I tried googling without success
till now. I'm litle bit disappointed as my 1-wire network is fully
installed and I want to use sheevaplug instead of Windows from now.
some more info saying (according to my very basic knowledge)
things seems okay for the usb-adapter driver (PL2303)
