Nut upsdev - Jan 2010 - blazer_usb vs. Ippon Smart Power Pro 1400

Hello 2All.

Today I had purchased Ippon Smart Power Pro 1400 UPS for my home PC.
It is a higher class device relative to Ippon Back Pro model line. It has one
RS232 port and one USB port to connect the monitoring station to. UPS talks with
megatec protocol, RS232 works as usual. USB connection is done through Cypress
Semiconductor usb-to-serial chip (VID/PID: 0665:5161) and it gets detected by
blazer_usb and works normally 'out-of-the-box' on my Fedora 8
installation (NUT
version compiled from trunk r2240, stock Fedora's libusb 0.1.12-10).

With libusb version from RHEL4 compiled for Fedora 8 there were no success in
getting device to work. I had tried every subdriver but it looks like this
device it pretty much buggy just like the Phoenix one used in Ippon BackPro and
it requires slightly different reading scheme to work with RHEL4 libusb. Will
test it on CentOS 4.8 tomorrow.

The 'ippon' subdriver from r2240 is broken. You need at least r2241  
for it to work (but better use the latest one).
