Installed a new Tripplite Smart1500LCD on a CentOS 7 host using the usb connector. Nut does connect: $upsc ups battery.charge: 100 battery.runtime: 1407 battery.type: PbAC ... But after a half hour or so the connection is lost. Restarting nut re-establishes the connection. Any idea what might be causing the dissconnection?
Can you send me the serial number (at least 1st 12 characters, see: https://www.tripplite.com/support/identify-products) and lsusb -v output for the UPS?

I solved this problem a few years back. https://github.com/sdgathman/trippfix The short answer is USB is broken on the model (but the power management is excellent, handling switchover to generator power without a hitch). The workaround is to do a usb port power off when the Tripplite USB hangs. But hubs that actually implement this mandatory feature (must at least support powering all ports off) are getting hard to find. The USB chips implement it just fine. The hubs don't bother connecting the pins and just wire to +5V. The good news is that with CentOS-8, the kernel automatically does the port power off, so you don't need my kludgey software fix when you go to 8. You still need an actual standard conforming USB hub however. If the port on your server isn't, you can buy an external hub like I did.

However the UPS appears to have dropped off completely. lsusb no longer shows the unit at all. So I physically unplugged and replugged it: #dmesg ...
