Hi,

I don't see any errors in the USB log. The usbdump needs to be started 
before you plug the device and before starting blazer_usb. Also you need 
to find the exact bus and "-f" device number which corresponds to your 
device. Use usbconfig to find this information.

Can you:

ktrace /usr/local/libexec/nut/blazer_usb -a UPSonic -u root -DDDD

When finished:

kdump | gzip > blazer_usb.log.gz

And send it to me off-list.

The USB trace looks normal.

--HPS
