I found this thread : http://askubuntu.com/questions/640308/after-upgrading-to-2015-04-virtualbox-crashes-at-windows-vm-start-nothing-in-l "To solve the problem and use your VM with USB2.0, what I did is to update the Oracle VM Virtualbox ExtensionPack to the same version: 4.3.34r104062" Indeed, I had installed Virtualbox ExtensionPack to the same version: 4.3.34r104062 when I had downgraded Virtualbox (version 5.0 to 4.3.34). Oddly : - version 5 of virtualbox informed me that the version 4.3.26 of the extensionPack was not correct -> I install extensionPack version 5 - After downgraded, version 4.3.34 of virtualbox informed me that the version 5 of the extensionPack was not correct -> I Install ExtensionPack to the same version - But initially, when I had upgraded from 4.3.26 to 4.3.34, VirtualBox didn’t inform me that the Extension Pack 4.3.26 version is not correct. VM's Start ... and crash ... I do not know if this bug should be closed. Perhaps this could happen to other people.
