Right. This is perhaps a matter of setting up the correct hotplugging
scripts, but I am not sure how to do it for the /dev/hiddev interface.
In any case, the old hidups driver will be discontinued soon, and is
not actively supported any more.

Drats, you're right. I though this feature was in 2.0.3, but actually
it was introduced afterwards. If you get the current development
sources from SVN, you would be able to run this. In any case, you
would need the newest version for Tripp Lite support.

Not very much, unfortunately. 

In case you feel like experimenting with this, I am attaching a patch
that *might* enable this device to be supported by the newhidups
driver, when applied to the current development version from the SVN
repository. Some fine-tuning will probably be required, for which the
output of "newhidups -u root -DD -x generic -x vendorid=09ae auto"
would still be useful.
