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:
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.
