It's one of their lesser transgressions :-)

Bear in mind that the usb.ids file is a composite of the official company names (for idVendor, probably grabbed from usb.org documents) and idProduct values observed in the wild. If Cyber Power chooses to reuse the idProduct 0x501 across all of their models in that class, that's fine, as long as their HID descriptors report any actual data format differences.
