Hi all,

Couldn't test SVN version. After downloading, autoreconf --install gives 
me the following output:

# autoreconf --install
aclocal: macro `NUT_OS_FUNCTIONS' required but not defined
aclocal: configure.in: 65: macro `AM_PROG_CC_C_O' not found in library
autoreconf: aclocal failed with exit status: 1

Maybe I'm missing something... However, I've tried last testing version 
(2.4.0-pre2), because it seems to include the same version of 
blazer_usb.c, blazer.c and blazer.h (checked with diff). At first, it 
seems to detect the UPS properly:

# bin/blazer_usb -a unitek -u root -x vendorid=0665 -x productid=5161 

Network UPS Tools - Megatec/Q1 protocol USB driver 0.02 (2.4.0-pre2)
Supported UPS detected with megatec protocol
Vendor information read in 1 tries

But if I try to send a shutdown command:

# bin/blazer_usb -a unitek -u root -x vendorid=0665 -x productid=5161 -k
Network UPS Tools - Megatec/Q1 protocol USB driver 0.02 (2.4.0-pre2)
Initiating UPS shutdown
instcmd: command [shutdown.return] failed
instcmd: command [shutdown.return] failed
instcmd: command [shutdown.return] failed

And giving more debug information:

# bin/blazer_usb -a unitek -u root -x vendorid=0665 -x productid=5161 
-DDDDD
Network UPS Tools - Megatec/Q1 protocol USB driver 0.02 (2.4.0-pre2)
debug level is '5'

And it seems to stand forever sending those Q1 commands...

Well, it seems we've advanced somehow... at least I can read some values 
from the UPS now. But I really need the shutdown command to work...

By the way, trying to execute upsd:

# /usr/local/ups/sbin/upsd
Network UPS Tools upsd 2.4.0-pre2
listening on 127.0.0.1 port 3493
Can't connect to UPS [unitek] (blazer_usb-unitek): No such file or directory

It doesn't seem to find blazer_usb binary... but it exists, and it's in 
the path:

# ls -al /usr/local/ups/bin/blazer_usb
-rwxr-xr-x 1 root staff 60599 2009-01-27 11:08 /usr/local/ups/bin/blazer_usb

# echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/ups/bin:/usr/local/ups/sbin

Sorry for my looong mails... and thank you a lot for your help and for 
making NUT possible! It's a great tool! :D

Maybe we'll finally get working this little and silly UPS...
