I also noticed the port utilisation value flash up a high value before returning to 0. Too fast to read the actual \r\n\r\nvalue from the screen update.\r\n\r\nThe same board when accessing CLI over USART1 works flawlessly.\r\nThe same board when accessing CLI from terminal emulator (putty) works flawlessly.\r\n\r\nSo seems to be something to do with the way that the configurator is managing the serial port and/or some interaction between USB VCP drivers and chrome.  \r\n\r\nI I have seen the same thing on multiple development boards as well as a virgin CC3D board , so doesn't look to be hardware specific. \r\n\r\nAnyone got any ideas what it might be / where to look.\r\n\r\nLong term I don't think i'm going to use VCP on my custom boards, but throw in a CH340G on usart1 instead to simplify reflashing anyway - but maybe beneficial for CC3D users if fixed."},"comment":{"url":"https://api.github.com/repos/cleanflight/cleanflight-configurator/issues/comments/147547011","html_url":"https://github.com/cleanflight/cleanflight-configurator/issues/254#issuecomment-147547011","issue_url":"https://api.github.com/repos/cleanflight/cleanflight-configurator/issues/254","id":147547011,"user":{"login":"tracernz","id":9995998,"avatar_url":"https://avatars.githubusercontent.com/u/9995998?v=3","gravatar_id":"","url":"https://api.github.com/users/tracernz","html_url":"https://github.com/tracernz","followers_url":"https://api.github.com/users/tracernz/followers","following_url":"https://api.github.com/users/tracernz/following{/other_user}","gists_url":"https://api.github.com/users/tracernz/gists{/gist_id}","starred_url":"https://api.github.com/users/tracernz/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/tracernz/subscriptions","organizations_url":"https://api.github.com/users/tracernz/orgs","repos_url":"https://api.github.com/users/tracernz/repos","events_url":"https://api.github.com/users/tracernz/events{/privacy}","received_events_url":"https://api.github.com/users/tracernz/received_events","type":"User","site_admin":false},"created_at":"2015-10-12T23:18:48Z","updated_at":"2015-10-12T23:18:48Z","body":"Good work. :) Hopefully somebody can sort it out.
