BigNG everything works except temp sensors

[despat]

I've connected a BigNG monitoring two pumps (Cpu and GPU). The flowmeter sensors work fine and the fans can be controlled manually. But I can't get any temp readings. There are two digital sensor and they ping ok (light up) but no reading from either the digital or the other 8 analog sensors. The USB drivers seem fine and I even updated the firmware from 2.6 to 3.2 without any problems (so the USB must be working). Is there anyway to check why temps don't show??

Thanks
