Description of problem: I have two MGE nova 1100s with usb connections and one is working on rawhide and the other is not working with F16.

Clear Chat Comfort USB Headset Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
1) what version of glibc do you have? 2) what is output of: id nut 3) what is output of lsusb ll /dev/bus/usb/* what debug messages reports ups driver? (look at /etc/ups/ups.conf for name of your ups and driver used), than start: <upsdriver> -DDD -a <name of ups> for [myups] driver = usbhid-ups port = auto desc = "My ups" it'd be: usbhid-ups -DDD -a myups

I checked id nut on the machine where nut was working and saw: [root@bruno bruno]# id nut uid=57(nut) gid=57(nut) groups=57(nut),18(dialout) Does nut need to be in the dialout group?
Thanks for providing requested information. This is a known issue, glibc is broken. It's the reason why "id nut" does not show nut is member of dialout group. *** This bug has been marked as a duplicate of bug 745675 ***
