In a multi-DS9490 setup, you may want to identify the adaptor by port.
We don't have a tool for that yet, so it would be nice if your tool
covers this, too. In the end, we can come up with a better scheme that
-u -u2 and so on.

That information seems outdated. The adaptor board which came with my
DS28E17 eval kit says DS9481P-300 and it is based on a MAXQ1010 µC. Not
much else in there, the schematics from their datasheet don't match the
circuit at all.
So, don't check for a PL2303 in there but for 0b6a:5a03. The driver is
cdc_acm rather that pl2303. It works with owfs as a DS2480 on /dev/ttyACMx.
Kind regards
