This may due to that it is not responding to the info comand (I/cr).
You can test it like this.

/path/to/blazer_usb -DD -a mustek -u root

If you get any 'short reply' or 'invalid start character'.
The mfr model and serial is from the same function.

What happens if you wait. Some ups'es need to have a serten charge level
to start. This to manage a power-out after power on.
If it starts direct, and the battery is empty, it would shut off before a safe 
powerdown.
