I don't have the previous threads in memory, and the old
lists are offline, so we'll dig a new time.

drop hidups, as it will soon be abandonned to the profit
of newhidups...

it might be due to the version. newhidups needs 0.1.8
at least, to unbind hiddev from the device...
Try to upgrade libusb[-devel] and recompile

once done, launch newhidups in debug mode (newhidups -DDDDD auto)
and send us back the output. We'll see what data are supported
and how we can add this to newhidups (if possible).
IIRC, there was some non standard HID usage, and few data.
That maybe also was Tripplite that implemented its serial
protocol over HID (non sense!)
