When I start up only the libfreenect2 driver or the webcam separately they both work fine. However, if I try to run both of them at the same time I get the following error when trying to open the camera\r\n```\r\nVIDIOC_STREAMON error 28, No space left on device\r\n```\r\nI normally get this error when I am trying to use two usb 2.0 webcams and the USB 2.0 bus cannot handle the bandwidth, but I am only using one camera.\r\n\r\nDoes the Kinectv2 use USB2.0 in addition to USB3.0 or is libfreenect2 incorrectly allocating bandwidth on the usb2.0 bus?\r\n\r\nLinux walrus 3.13.0-48-generic #80-Ubuntu SMP Thu Mar 12 11:16:15 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux"},"comment":{"url":"https://api.github.com/repos/OpenKinect/libfreenect2/issues/comments/88865455","html_url":"https://github.com/OpenKinect/libfreenect2/issues/198#issuecomment-88865455","issue_url":"https://api.github.com/repos/OpenKinect/libfreenect2/issues/198","id":88865455,"user":{"login":"floe","id":90756,"avatar_url":"https://avatars.githubusercontent.com/u/90756?v=3","gravatar_id":"","url":"https://api.github.com/users/floe","html_url":"https://github.com/floe","followers_url":"https://api.github.com/users/floe/followers","following_url":"https://api.github.com/users/floe/following{/other_user}","gists_url":"https://api.github.com/users/floe/gists{/gist_id}","starred_url":"https://api.github.com/users/floe/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/floe/subscriptions","organizations_url":"https://api.github.com/users/floe/orgs","repos_url":"https://api.github.com/users/floe/repos","events_url":"https://api.github.com/users/floe/events{/privacy}","received_events_url":"https://api.github.com/users/floe/received_events","type":"User","site_admin":false},"created_at":"2015-04-02T10:59:07Z","updated_at":"2015-04-02T10:59:07Z","body":"Two generic suggestions for most USB problems include:\r\n* try a more recent kernel, e.g. 3.16 from package linux-image-generic-lts-utopic\r\n* if possible, try a different USB3 controller, I think this kind of bandwidth allocation issue often happens with Intel controllers"}}
