[Nut-upsdev] no serial number for Tripp-Lite SMART3000RM2U?

[Seth Galitzer]

I'm trying to set up a single host to monitor the state of several UPS 
in my data center.  I have a mix of several APC and Tripp-Lite in 
production.  The former are great, the latter are not so much.  With the 
APCs (using usbhid-ups), I can set up configs for each based on the 
value they report from ups.serial.  With the Tripp-Lites (using 
tripplite_usb), there is no value returned for ups.serial (serial=12345 
in ups.conf), and debug output says the serial is "unknown".  The driver 
does read a "Unit ID" value, but this appears to be the same for all 
devices and I have not yet found a way to configure this in the device 
firmware manually.

Are there any plans to support this in the near future?  Is there 
anything I can do to help support this?  I would like to be able to 
check all of the UPS from a single host, but without a way to 
differentiate them, I'm out of luck.

Thanks.
Seth

System specs are as follows:
OS: Ubuntu 10.04.4
nut version: 2.4.3
installed from packages (but I also tried building 2.6.4 from tarball 
and just using that version of tripplite_usb with same results)
device: Tripp-Lite SMART3000RM2U
device info: http://www.tripplite.com/en/products/model.cfm?txtModelID=3025

debug output:

Some features may not function correctly.
