Bug 315939 – app-misc/digitemp-3.5.0 fails initialize ds1820 via ds2490 because device is busy

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Juergen Rose 2010-04-18 11:12:54 UTC]

'digitemp -w' and 'digitemp -i' are failing with the following output:

I get the same output as root and also if the ds1820 is not plugged into the ds2490.

Reproducible: Always

Probably best to report this upstream, especially considering that this package is currently orphaned.

[Comment 2 Wolfram Schlich (RETIRED) 2016-01-27 13:28:16 UTC]

Juergen, please retry with app-misc/digitemp-3.7.1 which is now in portage.
Feel free to reopen if the issue persists with that version. Thanks! :)
