RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Vladimir Benes 2016-05-09 11:56:24 UTC 
Description of problem:
I've tried to up device several times (like 20x) and after a while device seems to be dead. Neither MM restart nor for i in $(ls /sys/bus/usb/devices/usb*/authorized); do echo 0 > $i; done; for i in $(ls /sys/bus/usb/devices/usb*/authorized); do echo 1 > $i; done helps.

other machines still work so it's not a BTS issue

Comment 5 Dan Williams 2016-07-19 15:36:37 UTC 
CME error 277 means "not disconnected", and that should be fixed upstream already by https://bugs.freedesktop.org/attachment.cgi?id=123525.
Comment 6 Dan Williams 2016-07-19 15:40:04 UTC 
Vlad, can you re-test this bug with Lubo's latest COPR with ModemManager-1.6-0.4.20160615git8080be8.el7 ?  That should contain the necessary fix.

seems the correct BZ is https://bugs.freedesktop.org/show_bug.cgi?id=95302

and the commit that got merged to upstream is https://cgit.freedesktop.org/ModemManager/ModemManager/commit/?id=55f3ab80835114342618083664c4fa585455b9e0


Already released with 1.6.0, and thus part of current builds.
Move to MODIFIED.
Comment 10 Vladimir Benes 2016-08-29 12:46:18 UTC 
still somehow seeing this.. not sure if it's device specific as some devices are not affected.
Comment 11 Vladimir Benes 2016-09-28 16:05:38 UTC 
Behavior is far better, and these failures can be caused by BTS as well. Failure rate is something around few % so nothing serious.
