[Bug 1088395] Re: 18ec:3299 Can't read uvcvideo (usb video / webcam) device
Hi, I have limited internet access on the PC where I can reproduce the bug. Actually, I can test the dev release but after two weeks or so. I'll add the comment when done.

Alan, thank you for your reply. May be in the future this bug will be fixed. I understand it's not a simple bug. I will not send any messages concerning this bug anymore. When I tested the camera on other two machines running Ubuntu it showed the same log message but it worked: not running at top speed; connect to a high speed hub Just for interest, found similar bug on launchpad: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1088395 Egor 2012/12/17, Alan Stern : > On Mon, 17 Dec 2012, [KOI8-R] Егор Орлов wrote: > >> Guys, possibly found bug in usb host controller. > > This is not a new bug; it has been known for many, many years.

I tested it with no usb devices plugged in except the camera both on bus 1 and 2 with the same result. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1088395 Title: Can't read uvcvideo (usb video / webcams) devices To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1088395/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Joseph, just tested it with the latest raring kernel downloaded from the links.

[Bug 1088395] [NEW] Can't read uvcvideo (usb video / webcams) devices
Public bug reported: Attempting to read /dev/video0 for USB video device gives: libv4l2: error turning on stream: No space left on device I tested the camera: Bus 002 Device 006: ID 18ec:3299 Arkmicro Technologies Inc. The hardware on that machine, is ok. I also have win7 installed and the camera works in it. I tested this camera on other two machines with Ubuntu 12.10 and it works out of the box (luvcview, guvcview). I was unable to boot with latest mainline kernels (3.7rc8 or 3.6.9) to test whether the error remains. Although in ArchBang live cd (3.6.9 kernel) the same error still was there when I tried to capture.
