Sadly there is a small flaw in the krauler subdriver here and it  
doesn't output the data it has read from the UPS. But since it doesn't  
report a failure here, it means that it has successfully read  
something. Add the fact that the megatec_usb driver was able to talk  
to your UPS probably means that it returns 46 bytes in the reply  
(sufficient for megatec_usb) and not 47 (which is required by  
blazer_usb). Most likely, the terminating '\r' which is expected is  
not part of the reply. I've made it optional in the development  
version, so it will be in the next released version. If you're able to  
build from sources, you can modify line 189 in drivers/blazer.c from

	if (blazer_command(cmd, buf, sizeof(buf)) < 47) {
to
	if (blazer_command(cmd, buf, sizeof(buf)) < 46) {

and compile the driver again. Otherwise, running the megatec_usb  
driver from nut-2.4.3 is the only alternative.

Best regards, Arjen
