Please explain "1-wire device." I spent my life in electrical engineering, and with virtually zero exceptions, it always took at least 2 wires to transfer any information or control. (There was something called "G-Line" but I never saw an example of it. Supposedly, it worked as an RF transmission line, and needed launcher cables at each end of several feet.) I realize that an antenna can be thought of as a "1-wire" device, but I don't think that's what the writer had in mind. --doug At 06:05 PM 1/30/2005 -0500, Paul Alfille wrote:
I use 1-wire devices -- little chips and buttons made by Dallas Semiconductors that can monitor temperature, humidity, voltages, and switch things on and off.
In fact there is quite a community around them, with everything from home HVAC and weatherstations, to door access control.
The devices connect through either a serial or USB adapter, and that's where my problem lies. I head a software effort that has adapted the chips to linux, as a filesystem, among other ways. See http://owfs.sf.net
It worked perfectly until SuSE 9.2 -- and the reason is SUSE now includes a kernel module ds9490r that attaches to the 1-wire USB adapter. And does nothing. It is an idea with no implementation.
Unfortunately, I have to manually rmmod the module before my software, which uses libusb can attach to the device.
I understand the wish to make SuSE as totipotent as possible out of the box. Loading a module with no utility that breaks existing software doesn't help, however.
So, as simpler question, how do I disable autoloading of the ds9490r?
