If I try to start it with root priveleges, I see thouse errors:
# /lib/nut/megatec_usb -a sven_625 -D -u root
Network UPS Tools - Megatec protocol driver 1.6 (2.4.1)
Serial-over-USB transport layer 0.10
debug level is '1'
Starting UPS detection process...
0 out of 5 detection attempts failed (minimum failures: 2).
Cancelling any pending shutdown or battery test.
Megatec protocol UPS detected [  VT0105BG].
12.0V battery, interval [9.7V, 13.7V].
Done setting up the UPS.

The error handler usb_comm_fail() in megatec_usb() is over reacting here. The libusb library is clearly stating that there is no error here, so reconnecting is probably not the best thing to do.

Best regards, Arjen
