I suspect, the UDEV daemon grabs the device first and only after it cannot find a suitable driver, it releases the device.\r\nStrictly this is probably not an AP2 bug, but there should either be a solution in the documentation or maybe a suitable blacklist file in the Linux package.\r\nI will try to investigate what exactly causes the problem and post a solution as I find it."},"comment":{"url":"https://api.github.com/repos/diydrones/apm_planner/issues/comments/110997940","html_url":"https://github.com/diydrones/apm_planner/issues/731#issuecomment-110997940","issue_url":"https://api.github.com/repos/diydrones/apm_planner/issues/731","id":110997940,"user":{"login":"sgofferj","id":3258466,"avatar_url":"https://avatars.githubusercontent.com/u/3258466?v=3","gravatar_id":"","url":"https://api.github.com/users/sgofferj","html_url":"https://github.com/sgofferj","followers_url":"https://api.github.com/users/sgofferj/followers","following_url":"https://api.github.com/users/sgofferj/following{/other_user}","gists_url":"https://api.github.com/users/sgofferj/gists{/gist_id}","starred_url":"https://api.github.com/users/sgofferj/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/sgofferj/subscriptions","organizations_url":"https://api.github.com/users/sgofferj/orgs","repos_url":"https://api.github.com/users/sgofferj/repos","events_url":"https://api.github.com/users/sgofferj/events{/privacy}","received_events_url":"https://api.github.com/users/sgofferj/received_events","type":"User","site_admin":false},"created_at":"2015-06-11T04:51:41Z","updated_at":"2015-06-11T04:51:41Z","body":"@froller Could you try adding the rules file and restart the udev service as I described above in https://github.com/diydrones/apm_planner/issues/731#issuecomment-110632463 ?
