[Nut-upsuser] Tripp-Lite USB constantlly disconnecting.

[Shade Alabsa]

Hey, was wondering if I could get a quick sanity check. We have a SmartUPS
1500 RM2U which we have connected to a box via USB. It seems like every
40-45 seconds it becomes disconnected and reconnected. Though this only
happens when we have NUT enabled, otherwise it's fine. When it is
disconnecting and reconnecting running lsusb doesn't show it disconnecting.
After having it sit like that for a day NUT was unable to connect to the
driver.

So I was wondering does NUT do anything which would cause the USB to
disconnect? I didn't think so and I couldn't find anything yet it's quite
possible I missed it. I've tested this with CentOS 6.5 and Fedora 20. With
CentOS we were using nut-client-2.6.5-2.el16.x86_64 and
nut-2.6.5-2.el6.x86_64. With Fedora we were using nut-2.7.2-1.fc20.x86_64
and nut-client-2.7.2-1.fc20.x86_64.

Here is what the logs look like -
