I didn't know - thanks. However, I'm stuck with it - it's not our hardware. I'll mention it to the supplier next time they come in. Meanwhile, I have to get the driver working, but what I'm hearing is that nobody else will be interested - or at least, not as part of the standard sensors release. Is there anything in the code that will actively stop a chip driver using it? I can live without i2cdetect and sensors-detect for this one. I'll I2C_DRIVERID_EXP0 for it to avoid clashes. On a lighter note - I asked our IT department if they had recently started blocking the CVS port (2401) on the firewall and explained why I was asking, and got the reply "so what web page can't you see?" Ho-hum - off to do a bit of education.. I can telnet to port 80, but not 2401. I'm still betting on a firewall, most likely the one here. John.
