I had the same problem.

Solution: emerge -1av =dev-python/python-exec-10000.2

Motherboards are designed ground-up starting with power regulation, then CPU and memory, then peripheral devices.

(Note that the core design, like the CPU and memory, was likely done by the CPU vendor and just integrated into the OEM's design.)

What do you know is good? Are you sure your power ...

You have the right drivers: [94209.544389] uvcvideo: Found UVC 1.00 device <unnamed> (046d:0992)

It should work exactly the same in the built-in USB2 or USB3 ports. (The driver doesn't care what USB port it appears on.) The good news is, it works great on the PCIe USB ports which shows that the ...

Can you post the exact model of Logitech camera?

It still seems like there is some defective hardware. I don't know why or when the defect appeared, but a webcam shouldn't be claiming all the bandwidth of USB 2.0 much less USB 3.0.

Can you try the webcam on a different Linux box?

I have a uvc webcam. It seems yours is defective, especially as looks like it doesn't even handle the first steps of USB enumeration.

Do you have a link to someone reporting that your model of webcam works on linux?

I installed 3.8.11 and that fixed the problem.

I just picked up a cheap Logitech C270 webcam but can't get v4l2 to compile. I'm using the in-kernel webcam drivers.

The kind of detailed, in depth testing that Navar provides for his UD5H is way beyond what you would likely find for any other motherboard.

Doesn't mean you have to buy that one, but if it's at all interesting you'll have the best luck by using the info Navar is providing.

Navar mentions ...

I think Navar's answer is the best you can get.

You probably want a motherboard with a Z77 chipset, like Navar says.

Hopefully his Gigabyte GA-Z77X-UD5H also works for you. Then Navar can share any specific config needed to get everything to work.

If his motherboard isn't the one you want, please ...

I've had good luck with Asus motherboards for desktops. It sounds like you're building a desktop.

But to be perfectly honest, Asus does not support Linux so unless you want to choose a specific board and spend some time googling, you may end up with some problems. I'm guessing you want something ...

Why is the current trend in laptops moving toward tiny machines with large resolution, wimpy processors and small RAM?

In all ...

I'll check them out. I'm a little nervous buying that size monitor with that high resolution for that small an amount, don't see how they can do a good job of it.

But at least that would get me back to cards known to work on Linux. And maybe my existing card.

Thanks. Do some online research ...

That worked!

Ok, thanks! I'll put this info on the kernel bugzilla.

Have you looked at the korean catleap 27" 2560x1440 monitors?

If you pay a little more than the lowest, lowest prices (ebay usually has them for $390) you get more reliable service and the monitor will have DVI + VGA + displayport.

Obviously only DVI or displayport is needed to get a 3-way setup ...

This is a new install on an Asus F2A85-M/CSM, looking around I found [topic=952878]ethernet module crashes with IOMMU enabled[/topic], which the author marked solved but only because he got sound working. He never actually fixed the ethernet problem.

I've been in touch with at least one motherboard manufacturer I know personally. They were "unable to comment."

I'm assigning one full-time employee to coreboot.org.

I'll quote from your post the part I disagree with most: just buy a certificate, which you can use to sign your own kernel with I disagree for technical and philosophical reasons:

1. Technical reason: manufacturers will not -- they are not required to -- provide a "buy a certificate" option for ...

Don't count on it. Boards that come with Trusted Computing Module enabled cannot be used to boot anything but OEM OS. It is integral part of motherboard and cannot be removed. I'm hopeful that devices like the Wii, PS3, and XBox show the possibilities of replacing the TC/TPM BIOS.

However, I plan ...
