Which kernel version are you using?

Configuration looks good.

This part confuses me:

  68.487087     Checking device (09AE/3016) (004/008)
  68.564137     - VendorID: 09ae
  68.564168     - ProductID: 3016
  68.564174     - Manufacturer: Tripp Lite
  68.564220     - Product: TRIPP LITE UPS
  68.564225     - Serial Number: 2406CVLSM871900494
  68.564231     - Bus: 004
  68.564235     Trying to match device
  68.564255     Device does not match - skipping

Judging from the time, did the driver connect initially, or is it still trying to reconnect? (I haven't used "maxretry" before.)

After the errors from usbhid-ups, does "lsusb -vvv -d 09ae:" return valid information, or do you also get timeouts in syslog as well?

If lsusb doesn't work, it points to a problem between the UPS firmware and your Linux kernel version. (Well, technically, lsusb could be at fault, but it doesn't change as much as the kernel USB HCI drivers.)

In that case, you may want to check with Tripp Lite; they were kind enough to post results of testing their hardware against NUT and Linux. They should be able to repeat that test with Ubuntu 14.04.
