[Nut-upsuser] UPS Atlantis OnePower - VT12094S

[Andrea]

Hi, i have the ups in the subject. It is connected with usb cable.
With nut 2.4.3 it was working quite good with megatec-usb driver.
Now i just upgraded to nut 2.6 on my gentoo system and switching to
blazer_usb is not working.
Copying old megatec_usb driver from 2.4.6 and using it, everything
returns to function.
Some output with blazer_usb:

 * Service upsdrv starting
Network UPS Tools - UPS driver controller 2.6.0
Network UPS Tools - Megatec/Q1 protocol USB driver 0.03 (2.6.0)
No supported UPS detected
Driver failed to start (exit status=1)

                                                                     [
!! ]
 * ERROR:  upsdrv failed to start


with megatec_usb:
 * Service upsdrv starting
Network UPS Tools - UPS driver controller 2.6.0
Network UPS Tools - Megatec protocol driver 1.6 (2.4.3)
Serial-over-USB transport layer 0.10

What can I do to use the new, still supported and developed blazer driver?
Many thanks
