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.

strace output snippet following open of the usb device /dev/bus/usb/006/002

Description of problem:
usbhid-ups from the "nut" UPS monitor works as expected with libusbx-1.0.24-4.el9.  However, after updating to libusbx-1.0.25-2.el9.x86_64, it is unable to identify a USB attached UPS.

I'll attach two snippets of strace output, one that fails (with 1.0.25 installed) and one that works as expected (with 1.0.24 installed).  If those are not useful, please let me know what other information might be.

/etc/ups/ups.conf contains:

[apc]
        driver = usbhid-ups
        port = auto


Version-Release number of selected component (if applicable):
libusbx-1.0.25-2.el9.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Configure nut to monitor Back-UPS RS 1500MS, as above
2. Run "usbhid-ups -a apc"
3. Update to libusbx-1.0.25-2.el9.x86_64
4. Run "usbhid-ups -a apc"

Actual results:
usbhid-ups will report that it can't identify the UPS (info like "Manufacturer: unknown" and "Unable to get HID descriptor (No such device or address)") and exits.

Expected results:

Yeah, the CentOS version is messed up currently. I was working on solutions for Fedora, but haven't pushing anything new into CentOS had not been on my radar.

For now, I suggest downgrading to 1.0.24.
