you can unplug/plug/turn each device on and off as much as you like, and all will be okay. obviously this reloads the driver.Īlso this only happens from sleep mode. they don't cause problems between each other, and also they are on a different USB hub,Īlso once I do a rescan of the midi - the virus comes back. It would be very easy to 'blame' the other usb devices, but they are fine within themselves.
MAC OS VIRUS POLYGLOT SPEECHSYNTHESIZER MAC OSX
What appears to happen, is the scanning of the USB bus by the apps causes Mac OSX to decide the Virus is not there, and it disappears. (note on (c), if the usb devices are already present when the mac wakes, there appears to be no issue) neither is on the same hub as virus, and virus does it regardless of its port)ĭ) start an app that uses this secondary deviceĪs the app starts up, the virus devices disappear.
the computer in sleep ( and make sure it really is properly in sleep)Ī) wake up mac, let make sure its up an running properlyī) turn on virus (you will see midi device correctly becomes active, but the above error messages in consoleĬ) turn on another usb device (I've got two, an eigenharp and leap motion, but cause the same issue. Ive spent quite a bit of time isolating the issue, and i can say to reproduce I need the following steps: The only console messages I see, that appear to be from the Virus areġ1/4/14 12:17:55,649 sandboxd: () coreaudiod(177) deny iokit-open AudioUserClientVirusġ1/4/14 12:17:55,912 coreaudiod: Bundle Ref: ġ1/4/14 12:17:55,912 coreaudiod: Bundle Ref: ġ1/4/14 12:17:55,912 coreaudiod: Bundle Ref: ġ1/4/14 12:17:55,913 coreaudiod: Bundle Ref: ġ1/4/14 12:17:55,914 coreaudiod: Bundle Ref: ġ1/4/14 12:17:55,926 coreaudiod: PtLinearRegression::threadRun exit at slice 23ġ1/4/14 12:17:56,015 coreaudiod: PerformConfigChange Out, mInStreamingSuspended falseġ1/4/14 12:17:56,017 coreaudiod: PtLinearRegression::threadRun exit at slice 1ġ1/4/14 12:17:56,109 coreaudiod: PerformConfigChange Out, mInStreamingSuspended falseġ1/4/14 12:17:56,000 kernel: USB Sound assertion in AppleUSBAudioEngine at line 1274ġ1/4/14 12:17:56,000 kernel: USB Sound assertion in AppleUSBAudioDevice at line 1492ġ1/4/14 12:17:56,000 kernel: USB Sound assertion in AppleUSBAudioDevice at line 633ġ1/4/14 12:17:56,000 kernel: USB Sound assertion in AppleUSBAudioDevice at line 286īUT these come when the virus starts up, and it then works from that point. Its not obivousy ''sleep ' related, as i always turn off virus before mac is put to sleep, and turn virus on after mac is awake. i think perhaps once per session (though this might be due to opening daws once per session?) My suspicion is it appears to happen when opeing or closing applications that use midi ports,īut it doesnt happen every time. It does it either directly connected to iMac or via hub with 5.0.3 ( uve never used it earlier than this) Im using osx 10.9.1 with 5.0.7, but it also used to do it on 10. so simple solution, just a minor inconvience.ĭo others also see the midi device disappears, and have to rescan? ( i think turning off/on virus also reloads the midi device) The fix, is just to go to settings and to rescan midi, and it appears again. Sometimes even though the virus ti is plugged in and connected via usb and turned on the virus midi/synth device disappears. This is not a big issue, i just wonder if anyone else has noticed it.
