Now I get:

  botticelli:/usr/local/ups/bin# ./bcmxcp_usb -DDDD -u root -a botticelli-ups
  Network UPS Tools - BCMXCP UPS driver 0.10 (2.0.3)

  debug level is '4'

The UPS is device 2 on bus 2 indeed:

  botticelli:/usr/local/ups/bin# lsusb 
  Bus 005 Device 001: ID 0000:0000  
  Bus 004 Device 001: ID 0000:0000  
  Bus 003 Device 001: ID 0000:0000  
  Bus 002 Device 002: ID 06da:0002 Phoenixtec Power Co., Ltd 
  Bus 002 Device 001: ID 0000:0000  
  Bus 001 Device 001: ID 0000:0000  

Is there any way to change the "class/vendor specific interface
descriptor" into something that bcmxcp_usb understands?

Best,
Georg
