[Nut-upsdev] Newhidups gets unbound after a while

Strange. So the device first identifies itself as:

Checking device (0463/FFFF) (001/002)
- VendorID: 0463
- ProductID: ffff
- Manufacturer: MGE UPS SYSTEMS
- Product: ELLIPSE
- Serial Number: 1HDF44001
- Bus: 001

But after disconnecting, it identifies itself as:

Checking device (0463/FFFF) (002/002)
- VendorID: 0463
- ProductID: ffff
- Manufacturer: unknown
- Product: unknown
- Serial Number: 1HDF44001
- Bus: 002

In particular, the Manufacturer and Product become "unknown". This is
the reason NUT does not reconnect to the device; it cannot determine
that it is indeed the same device. (Also, in the example above, the
bus changed from 001 to 002, but this is because you plugged the UPS
into a different USB port for the two experiments; it does not bother
NUT).

The question is: why is this happening? I have no idea what might
cause this. Did you try unplugging and replugging the UPS while it is
connected? Will NUT reconnect to it then? Also, did you try unplugging
and replugging the UPS *after* it has disconnected itself? Will NUT
reconnect to it then?

Unfortunately, I am not a USB expert, and these strange behaviors
mystify me. 

@Arnaud, do you have any suggestions here?
