Re: 2.6.5 Sensors & USB problems

[Ian Morgan <imorgan@webcon.ca>]

Yeah, bad form to reply to one's self, but someone may appreciate this info:

Seems that the w83781d driver no longer detects whatever the sensor chip on
the P4PE is, but I see there is now a new driver called asb100 which does
work. An old conflicting lm_sensors install was breaking the sensors-detect
script, but once resolved it nicely detected the asb100.

Can anyone explain, however, why my i2c bus showed up as number 0 under
linux <= 2.6.4, and now always as number 1 under linux 2.6.5? The is no
number 0 any more.

Regards,
Ian Morgan
