[Bug 1483615] Re: usbhid-ups driver segfaults on discovery of UPS

[Charles Lepple]

@davis65536: I think we might have a lead on this. Are you running in a
VM?

https://github.com/networkupstools/nut/issues/258

The APC portion of usbhid-ups expects that if it can open the device, it
can read the string descriptors. Your system is printing "unknown" for
the Manufacturer, Product and Serial Number lines for your UPS. IMHO
this is also a bug elsewhere (libusb, kernel or hypervisor?) since the
Product string is the easiest way to distinguish between the various
051d:0002 USB devices, though I agree that the driver should be more
robust.

Can you see the APC vendor string if you run "lsusb -vvv -d051d:" as
root?
