Description Harald Milz 2011-04-09 16:31:42 UTC

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.

Comment 2 RHEL Program Management 2011-04-10 06:00:34 UTC

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.

Comment 3 Jay Fenlason 2011-04-21 20:30:13 UTC

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.

Comment 4 Harald Milz 2011-04-25 13:37:59 UTC

Apparently, with kernel 2.6.32-71.18.2.el6.x86_64 it does.

Comment 5 Jay Fenlason 2011-04-25 16:37:10 UTC

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.

Comment 6 Harald Milz 2011-04-27 14:19:21 UTC

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.

Comment 7 Harald Milz 2011-04-27 14:21:25 UTC

strange. It originally didn't work with the very same kernel release which is why I opened the ticket to start with.

Comment 8 RHEL Program Management 2011-10-07 15:30:02 UTC

Comment 9 John Feeney 2012-06-22 17:40:40 UTC

So should this be closed as NOTABUG?
