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.

The eject was done on the guest but not on the client, right ?
> GSpice-CRITICAL **: usbredirhost: error resetting device:
> LIBUSB_ERROR_NO_DEVICE
The device is not plugged to the client machine anymore, so it's
expected a reset sent to it fails.
The reset is sent by usbredirhost when releasing the device:
/* reset the device before re-binding the kernel drivers, so that the
kernel drivers get the device in a clean state. */
Optionally, the code can check for this specific error-code
and not log an error in such a scenario.
To cleanly plug out the device:
1. On the guest - eject the usb device
2. File->Usb Devices menu - deselect the device
3. On the client - eject the usb device
4. Plug out the device
> The eject was done on the guest but not on the client, right ?
yes.

These steps work well.
