"Latest" doesn't sound like one of our version numbers :-) For Ubuntu  
10.04, I assume it's 2.4.3-1ubuntu3 as listed here: http://packages.ubuntu.com/lucid/nut 
  ?

You can get the full version by running "dpkg -l nut".

Usually, we're referring to the right side of "driver =" in ups.conf,  
but in your case, there may be a kernel driver involved as well. See  
below.

None of the NUT drivers use /dev/hidraw*. Also, it appears you have  
"port=" twice on the same line.

Are there any /dev/ttyUSB* device nodes? Do any appear if you run  
"sudo modprobe cypress_m8"? (Although I think that module would have  
been loaded automatically if needed.)

What do you get from "sudo cat /proc/tty/driver/usbserial"?

Basically, if the NUT driver name doesn't contain "usb", the driver is  
expecting a serial port device name (either one corresponding to a  
physical 9- or 25-pin port, or a virtual one created by a USB-to- 
serial converter driver in the kernel).

Another tip from the nut-upsuser thread is to start with the shortest  
possible entry in ups.conf (driver= and port= are required across all  
drivers), and build up as things start to work. In your case, I would  
try this:

[Ultra]
	driver = blazer_ser
         port = /dev/ttyUSB0

The guess of blazer_ser is due to the ULT line here:

http://www.networkupstools.org/stable-hcl.html?manufacturer=Powercom

Also, the entries below that for the "powercom" driver mention USB  
Product ID 0002, and the 0D9F:0004 entry in the syslog seems to  
indicate a Product ID of 0004.
