Hi all,
after a change of UPS (to Atlantis Host Power 851) I began to use the
new driver blazer_usb and compared to old one (blazer used with serial
connection) I noted more CPU use and errors in dmesg:
[...]

This is the configuration of the driver in ups.conf:
[ups]
driver = blazer_usb
subdriver = cypress
vendorid = 0665
productid = 5161
port = auto
desc = "AtlantisLand Host Power 851+"
Obviously the usb ports work good, I think is a bug in the driver or
something like..
Bye at all
Fabio C.
