Can you provide a pointer to details on the usbhid-dump tool? Not familiar with that one.

Depending on how much of the Power Device Class (PDC) HID spec they have implemented (rather than doing non-PDC HID as a cheap USB-to-serial replacement), this might require a separate driver, or it might be easy to extend usbhid-ups. The "explore mode" mentioned in the link below will provide the output to guide that decision.

Could you please also provide the output of "lsusb -vvv -d 04d8:0500" run as root?
