The "megatec_usb" driver was introduced in NUT 2.2.0 (the current
stable release).

"megatec" can only drive UPSes connected through the serial port, not
USB (unless your UPS has a true USB-to-serial converter, which I very
much doubt it, and gets assigned a "/dev/ttyUSBx" device by the
kernel).

The Winpower software speaks the megatec protocol, so "megatec_usb" is
your best shot. If it doesn't work, maybe its maintainers can help
modifying it in order to work.
