Thank you guys for your responses.
- The Nut version I have installed (from the Ubuntu repositories) is 
- The OS is Ubuntu server 10.04 LTS x64 with the 2.6.35-std210-amd64 kernel.
- Driver output:
root at www:/etc/nut# /lib/nut/apcsmart -DDDDD -a rack1ups
Network UPS Tools - APC Smart protocol driver 2.03 (2.4.3)

   35.029891     Unable to detect an APC Smart protocol UPS on port 
Check the cabling, port name or model name and try again

I'm looking on the NUT website and on Google, but I must be doing 
something wrong with the USB driver.  Here's the error output:

root at www:/etc/nut# /lib/nut/usbhid-ups -a rack1ups
Network UPS Tools - Generic HID driver 0.34 (2.4.3)
USB communication driver 0.31
Can't claim USB device [051d:0003]: could not detach kernel driver from 
interface 0: Operation not permitted

Here's my ups.conf:
   driver = usbhid-ups
   port = auto
#  vendor = "APC.*"
#  product=".*Smart-UPS.*"
   desc = "Rack 1 UPS"

If this helps, this is the dmesg output when the USB is plugged in...
