Because both NUT and lsusb are having trouble retrieving the HID Report Descriptor, I think the problem is at a lower level: probably between the UPS, the kernel, and the USB HCI. The archives have a number of unresolved emails about the 5E and "broken pipe" errors.

Probably worth checking with Eaton, too.
