Paul, my apologies for the delay in responding to your question - mail server crash.
Regarding statistics, all the error files in the error directory are "0". The error files in the bus directory are also "0". I added tracing to the i2c-dev module and there appears to be quite a bit of I2C_SMBUS read/write activity when fetching a channel value. So either some piece of data is being read or re-read multiple times (without error condition). I will start tracing through the ow_2450 and ow_ds2482 code. Do you sense I may have a problem here? regards, Bob On 2/14/07 Paul wrote: > Any errors seen in the "statistics"?

I'm just trying to rule out a problem with my hardware or elsewhere. ------------------------------------------------------------------------- Take Surveys. Earn Cash.
