Nut upsuser - Apr 2013 - ippon back power pro 700 on FreeBSD 9.1-R

Hello, i'm trying to use nut with ippon back power pro 700 on FreeBSD
9.1-R with USB driver blazer_usb, and connection with UPS is unstable.

I'm starting it:
office at root # /usr/local/etc/rc.d/nut start
Network UPS Tools - UPS driver controller 2.6.5

Connected to UPS [ippon]: blazer_usb-ippon
/usr/local/etc/nut/upsd.users is world readable

In /var/log/messages i see:

Apr 28 21:56:50 office upsd[90938]: mainloop: Interrupted system call
Apr 28 21:56:51 office upsd[91018]: /usr/local/etc/nut/upsd.conf is
world readable
Apr 28 21:56:51 office upsd[91018]: /usr/local/etc/nut/upsd.users is
world readable

then i start upsmon:

office at root # upsmon -D
Network UPS Tools upsmon 2.6.5
kill: No such process
   0.000000     UPS: ippon at localhost (master) (power value 1)
   0.000154     Using power down flag file /etc/killpower

   0.002115     Trying to connect to UPS [ippon at localhost]
   0.002953     Logged into UPS ippon at localhost

But then after a while blazer_usb process is exiting with something
like this message:

Apr 28 22:00:12 office blazer_usb[91017]: Permissions problem:
Input/output error
Apr 28 22:00:12 office upsd[91019]: Can't connect to UPS [ippon]
(blazer_usb-ippon): No such file or directory

before "Permission problem" blazer_usb print out error "send:
Unknown error".

it may work 1 hour or 5 minutes, but balzer_usb is failing after a while.

nut installed from fresh ports.

I can't move to blazer_ser - computer have no COM port. What can be
done in this situation?

If you need to get this up and running quickly, I would recommend getting a
USB-to-serial port that is well supported by FreeBSD.

The values you are getting with blazer_usb don't follow the same pattern as
some of the other USB issues seen on older versions of FreeBSD, so debugging
that could take a while.
