Thanks. I can confirm that both of the proposed solutions work. (I hadn't
realized that there was a newer version than 2.4.3; I guess my distro is
behind the curve.) Either adding productid=2010 to ups.conf or upgrading to
2.6.0 seems to bring joy. With 2.6.0, I get:

# upsc Tripp-Lite at localhost
battery.charge: 100
battery.runtime: 1305
battery.type: PbAC
battery.voltage: 13.5
battery.voltage.nominal: 12.0
device.mfr: Tripp Lite
device.model: Tripp Lite UPS
device.type: ups
driver.name: usbhid-ups
driver.parameter.pollfreq: 30
driver.parameter.pollinterval: 2
driver.parameter.port: auto
driver.version: 2.6.0
driver.version.data: TrippLite HID 0.6
driver.version.internal: 0.35
input.frequency: 59.8
input.voltage: 119.0
input.voltage.nominal: 120
output.frequency.nominal: 60
output.voltage.nominal: 120
ups.beeper.status: enabled
ups.delay.shutdown: 20
ups.mfr: Tripp Lite
ups.model: Tripp Lite UPS
ups.power.nominal: 900
ups.productid: 2010
ups.status: OL
ups.timer.reboot: 65535
ups.timer.shutdown: 65535
ups.vendorid: 09ae
ups.watchdog.status: 0

That all looks reasonable to me.
