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 of problem:
Red Hat Enterprise Linux Workstation release 6.0 (Santiago) (Corporate Standard Build) does not recognize Lenovo Thinkpad X201 Integrated Camera.
Version-Release number of selected component (if applicable):
/lib/modules/2.6.32-71.18.2.el6.x86_64/kernel/drivers/media/video/uvc/uvcvideo.ko v0.1.0
How reproducible:
always
Steps to Reproduce:
1. modprobe uvcvideo
2. dmesg, look for USB camera messages
3.
Actual results:
camera is not recognized
Expected results:
uvcvideo should recognize camera. However, the camera's USB vendor:product is 17ef:4816 (as opposed to v17EFp480Bd which is compiled into the driver). The correct vendor:product should be compiled in. Alternatively, module options vendor= and product= could be added, as in usbserial.

Since RHEL 6.1 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.
Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.
Can you confirm that the camera works with the most recent kernel? The only reason 17ef:480b is compiled into the kernel is to enable a quirk which presumably is not needed with a more recent (less buggy) camera.
Sorry, I'm confused. It does what? Works with a more recent kernel? Needs quirks? Quirks can be manually specified by loading the module with the quirks= paramater. The 17ef:480b specified UVC_QUIRK_STREAM_NO_FID which is 0x10, so try removing the uvcvideo module and reloading it with quirks=0x10 to see if that quirk is really needed with your hardware.
I meant to say, with this kernel it works out of the box w/o any quirks. Very slow when the cam'd object moves, but it works. Enough for video conferencing I suppose.
strange. It originally didn't work with the very same kernel release which is why I opened the ticket to start with.
