You may have better luck asking on the linux-usb mailing list, but they will want to know the version of the kernel that you are using, and the exact output dmesg. Sometimes, this error/warning is generated when the kernel requests extra identification from the UPS. It is most likely benign, unless there is a disconnection message like the following: [ 3.618015] usb 4-2: can't set config #1, error -84 [ 4.056102] usb 4-2: USB disconnect, device number 3 If the UPS logically disconnects, it will make it harder for user-space software like NUT to reliably communicate with it. -- Charles Lepple clepple@gmail _______________________________________________ Nut-upsuser mailing list [email protected] http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/nut-upsuser
