ok, I'm raising this again... as I've got another usb device ( a KM softstep) and its the same with that as well... so it appears to be all usb devices, and its becoming increasing awkward to workaround. (so much for usb plug n play :))
heres the email I've sent to support, so it can be taken up as an official bug/request...
also as I said
- not using sleep mode, is not really viable, as I use the mac alot, so rebooting each time is unworkable
- not adding devices later is unworkable too, partly as the virus is hogging an entire USB bus, so I cannot keep things plugged in, and also because during startup there is a race condition in mac osx regarding which devices will get initialised first, there is a high chance that the virus synth driver will be started before other devices, and so then disappear .. this is outside my control. (also some usb devices only load a proxy usb device, and then create another usb device when the application using it starts)
as I said at the end, given its happening on 2 mac (of very different ages), 2 versions of osx, and with 4 different usb devices - I'm sure it must be pretty easy to reproduce.
thanks for your help
Mark

Ive raised this before on the forum here:
mac osx - virus midi device disappears (which you can get the details from)
the issue is simple
if i put the iMac to sleep, when I wake it up if I turn on and after plug in any other USB devices - Virus synth will disappear, and I can only get it back by rescanning (in audio device)
notes:
I'm on 10.9.2/5.0.7 but it was also doing this on 10.8/5.0.3
it does it on two different iMac that I have it on ( a 2007 and a 2013!)
it occurs with 4 different usb devices I have
there is nothing in the console log, showing any kind of error, see forum post.
it happens 100% every time with every usb device* i have
I've tried all other usb ports, its the same
it happens if i put the virus on a hub or not
steps to reproduce are very simple
a) Start with mac awake with Virus attached with USB (and other usb midi devices, though not relevant yet)
b) remove or turn off other usb device *
c) now turn virus off ( leave plugged in) - in audio midi device you will see virus midi go grey
d) put mac to sleep (wait for it to go into sleep, its not instant, leave about 30 seconds at least)
e) wake mac up
f) turn on virus, virus midi will correctly become active and be fine for use
g) plug in/turn on another usb midi device (and start an app that uses it)
h) ***** virus midi will have disappeared! ***** you can verify in audio device setup
i) audio device setup / rescan midi, virus reappears... and from this point, you can unplug usb devices as much as you wish, and it will remain (until you put it to sleep again)
usb devices I have that this happens with (any ONE of these, will provoke the issue)
- leap motion
- eigenharp pico
- eigenharp alpha (connected via basestation)
- keith mcmillan softstep
this is become a real pain, because due to the virus 'issues' with usb, i cannot really keep all devices plugged in (due to virus having to have its own usb bus), so i need to swap and change usb devices.
ableton, doesn't like the rescanning... if you do the above process, you will end up with a Virus Synth #2, so you have to change your live sets to use this, and then not save i.e. you end up having to restart Ableton.
this means my own workaround is to connect every usb device, possibly starting relevant apps, and only then turn on the virus... this is increasingly becoming 'unworkable'
please could the developers take a look, I find it hard to believe it cannot be reproduced, given i can do it on 2 versions of OSX, 2 different iMacs in combination with 4 different USB devices,
please could you also confirm you can reproduce.
usb is suppose to be plug and play and all my other devices are... so would be nice to get the Virus playing nicely
Thanks
