Well, I have good news and bad news.
I have a Tripp Lite SmartPro UPS attached to a Linux server running Ubuntu
5.10, and I'm running the just-released nut 2.0.3.
I had error -71 from the UPS, which Charles Lepple correctly called out as
a likely cable problem (thank you, Charles.) The cable provided with the
UPS by Tripp Lite was just plain bad. Not too long, mind you- defective.
I won't bore you with the steps I used to prove it- but trust me, I proved
So the uhci_hcd module now loads peacefully. lsusb spots the ups. The
vendor id is 09ae, product id 0001- correct. And starting tripplite_usb
as root, port auto, says:
Detected a UPS: TRIPP LITE/TRIPP LITE SMART1050SLT
then there are a splash of "unknown" messages, of which the killer is:
Unknown protocol (3004) attached to Tripp Lite SMART1050SLT
Uh-oh. 3004 is new. tripplite_usb only speaks 3003.
Yes, Tripp Lite has a shiny new undocumented protocol, folks. It is
probably based on 3003- but who knows?
One step forward, two steps back.
