It went up to 12.8v just now and seemed to stay there, but 13 is a good number.

Alas, a new problem.

On the server, I could use upscmd fine, but here on my test bench I can't (syslog):

...attempting to start the driver manually fails too:

...and as you'd expect:

Damn thing is sitting here beeping at me while I wait for it to discharge and I'm just trying to get upscmd working so I can turn the beep off :(
It also seems that the only way I can communicate with it is via megatec_usb -a plexus -u root

...anything else and I get:

...and so on.

I've tried side-stepping the issue by chown'ing and chmod'ing /dev/usb/hiddev0 to nut:nut & 777, to no avail. The above logs are from the binaries I 
built, but I get the same from the distro binaries.
