[Nut-upsuser] Eaton 1500 USB constant disconnections

[Spike]

Hi,

I have a eaton 1500 that connects to an Ubuntu Xenial box via USB. The UPS
works, however exactly *ever 5 minutes* it disconnects and reconnects and I
see this in syslog:

Mar 10 19:50:32 spike kernel: usb 4-5: USB disconnect, device number 103
Mar 10 19:50:33 spike kernel: usb 4-5: new low-speed USB device number 104
using ohci-pci
Mar 10 19:50:34 spike kernel: usb 4-5: New USB device found, idVendor=0463,
idProduct=ffff
Mar 10 19:50:34 spike kernel: usb 4-5: New USB device strings: Mfr=1,
Product=2, SerialNumber=4
Mar 10 19:50:34 spike kernel: usb 4-5: Product: Ellipse PRO
Mar 10 19:50:34 spike kernel: usb 4-5: Manufacturer: EATON
Mar 10 19:50:34 spike kernel: usb 4-5: SerialNumber: P344G46HW9
Mar 10 19:50:38 spike kernel: hid-generic 0003:0463:FFFF.1221:
hiddev0,hidraw2: USB HID v1.10 Device [EATON Ellipse PRO] on
usb-0000:00:12.0-5/input0

does anybody have any clue why that's happening? besides spamming the logs
I'm afraid that it may not reconnect at some point and/or fail when it's
actually needed.

thanks,

Spike
