[Nut-upsdev] Megatec_usb driver

[Dmitry Bely]

Trying to use it with Sven Smart RM2000 (seems to be an OEM clone of
Sysgration Smart RM UPS: http://www.sysgration.com/product.asp?KID=7).

I have just compiled the latest svn trunk. Unfortunately it does not
work with that UPS:

dbely at vserver1:~/nut-svn$ sudo /usr/local/ups/bin/megatec_usb -u root -a myups
Network UPS Tools 2.1.0 - Megatec protocol driver 1.5.3 [megatec_usb]

Serial-over-USB transport layer for Megatec protocol driver [megatec_usb]

Megatec protocol UPS detected [SVEN POWER Smart2U 2K Ver 1.1].
This UPS has an unsupported combination of battery voltage/number of batteries.
Cannot calculate charge percentage for this UPS.

If I enable debugging it loops forever:

dbely at vserver1:~/nut-svn$ sudo /usr/local/ups/bin/megatec_usb -u root
-DDDDD -a myups
