Belkin UPS F6S400auUSB incompatible?

I have the same... and I also when i disconnected the usb cable, my nas notified me that "a UPS has been disconnected"

I've dug some deeper digging.. and found that the UPS stuff is done by nut (http://www.networkupstools.org) so I tried to get it to work manually but hit a dead end. It seems that this and other Belkin UPSs are supported by nut, but the readynas does not have the nut driver installed.

from my readynas..

cat /proc/bus/usb/devices

T:  Bus=02 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#=  4 Spd=1.5 MxCh= 0
D:  Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs=  1

E:  Ad=81(I) Atr=03(Int.) MxPS=   8 Ivl=32ms

and a guy got it to work according to this forum thread..

back then the driver was the megatec_usb but according to the nut hardware compatibility list (http://www.networkupstools.org/stable-hcl.html) this should now work with the blazer_usb driver.

You can see from the nut HCL.. Universal UPS F6C1200-UNV USB (2007 models, vendor id: 0665) -> blazer_usb

Unfortunately.. the readynas does not have the blazer_usb driver

so we can only "hope" that one day Netgear include this nut driver and provide support...
unless somewhere knows how to compile this driver for the readynas and we make our own addon?
Once they include this driver.. then a whole heap of other UPS's should be supported :)
