More or less, yes.
It turns out that UPS vendors all have somewhat different interpretations of
the PDC spec.
There was an idea to create a generic fallback driver that could talk to any
USB HID PDC device:
https://github.com/networkupstools/nut/issues/112
But at the moment, when we suggest passing the 'productid = ' parameter to
usbhid-ups, it is because there is already a set of tables for that vendor, and
their model is not all that different from earlier models.
The nutdrv_qx driver might be more flexible in this regard, since we tend to
see different VID:PID combinations for devices that all speak one of several
easily identifiable dialects of the Megatec Q* protocols.
