Skype with web cam (usb) work only then I connect to USB 3 port: #lsusb Bus 003 Device 002: ID 046d:08b2 Logitech, Inc. QuickCam Pro 4000 Then I connect to USB 2 port on my mother board, v4linux not work and skype not found my web Cam Then this bug fixed?)
Usb 2.0 port: #lsusb Bus 001 Device 006: ID 046d:08b2 Logitech, Inc. QuickCam Pro 4000 As example not work on skype: skype Found Logitech Quick Cam Pro 4000 /dev/video0 but not show test and not work. I think this problem's in compiled kernel with support v2linux?
please provide us more info. 1) Had you test it with an open source application like xawtv or camorama? 2) Do you have libv4l package installed, and did you use: export =/usr/lib/libv4l/v4l1compat.so (32 bits kernel) or export =/usr/lib64/libv4l/v4l1compat.so (64 bits kernel) before calling skype? 3) If the same bug also happens with xawtv, please provide us the xawtv logs for using it on usb 2.0 port. Also, please provide the dmesg 4) If the same bug also happens with xawtv, please provide us the xawtv logs for using it on usb 3.0 port. Also, please provide the dmesg

(In reply to comment #9) > 1. Xamtv. Black box. > libv4l2: error turning on stream: No space left on device > ioctl: VIDIOC_STREAMON(int=1): No space left on device Ok. This means that you don't have enough bandwidth at the USB interface you're using for the traffic that the webcam would generate. Are you sure that this interface is really USB 2.0, and not an USB 1.x? If it is really an USB 2.0 interface, then it means that there are something connected on it (either externally or internally) consuming your USB bandwidth. You can check what bandwidth is available for a given USB port with: # mount -t usbfs none /proc/bus/usb # cat /proc/bus/usb/devices An USB 1.x port will appear there as: T: Bus=05 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=12 MxCh= 2 B: Alloc= 0/900 us ( 0%), #Int= 0, #Iso= 0 or T: Bus=02 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=12 MxCh= 2 B: Alloc= 29/900 us ( 3%), #Int= 2, #Iso= 0 An USB 2.0 port will appear there as: T: Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=480 MxCh= 8 B: Alloc= 0/800 us ( 0%), #Int= 0, #Iso= 0 The percentage at the "B:" lines show how much traffic is using it. Could you please post the result of cat /proc/bus/usb/devices, and the ports that you're trying to use for USB 2.0 and USB 3.0?

Hi, The logitech quickam pro 4000 is a USB 1 camera, and your motherboard no longer has so called companion controllers for USB 1 devices (all newer intel motherboards lack these), instead it has a build in USB 2 hub, and the Linux kernel has issues scheduling large USB isochronous transfers over a USB2 hub, this is a well known issue with the usb-ehci driver I'm afraid. Actually plugging the device into a USB3 port is a good workaround! We could change the component for this bug to the kernel, as this is a kernel issue, but this is a long standing issue requiring a major rewrite of the usb-ehci scheduling code, which I don't see getting fixed anytime soon. So I'm going to close this bug I'm afraid. Regards, Hans
