That was it, all right.  'mybox' needed to bre 'snark'.

But now I've got different troubles.  Trunk no longer detects the UPS.

root at snark:/home/esr/svn/nut/trunk# /usr/bin/upsdrvctl start
Network UPS Tools - UPS driver controller 2.1.0 (916M)
Network UPS Tools 2.1.0 (916M) - Megatec protocol driver 1.5.3 [megatec_usb]
Carlos Rodrigues (c) 2003-2007

Serial-over-USB transport layer for Megatec protocol driver [megatec_usb]

Megatec protocol UPS not detected.
Driver failed to start (exit status=1)

System log has many entries that say:

May 24 12:18:37 snark kernel: [136718.407859] usb 3-2: usbfs: process 26061 (megatec_usb) did not claim interface 0 before use

How do I troubleshoot this?
