multiple host user result in usb device driver not respond to plugin/out

Reported by: moo Owned by:
Component: USB Version: VirtualBox 4.0.2
Keywords: Cc:
Guest type: Linux Host type: Windows

Description (last modified by aeichner)

it's windows 7 here. i run everything below under administrator permission, either with administrator account or with UAC administrators permission

  1. login to "administrator" account, starts virtualbox, boot Gentoo linux

result: check procexp, i see process tree as service.exe -> svchost.exe -> VBoxSVC.exe (as Administrator account) (this is expected) result: plug in/out usb mouse or other device, it's fine

  1. switch to 'moo' account, start virtualbox with UAC administrators permission, don't boot any guest

result: check procexp, i see process tree as service.exe -> svchost.exe -> VBoxSVC.exe (as Administrator account), and VBoxSVC.exe (as moo account) result: plug in/out usb mouse or other device, it's fine

  1. close the one started by 'moo' account

result: check procexp, i see process tree as service.exe -> svchost.exe -> VBoxSVC.exe (as Administrator account), and VBoxSVC.exe (as moo account) hang around for a few seconds (this is expected)

all the result above is fine, expected. but here goes the problem

  • unexpected result: after a few seconds, "VBoxSVC.exe (as moo account)" is still there. it's expected to be terminated automatically
  • unexpected result: plug in/out usb mouse or other device, it's not detecting the plug in/out, the usb device(s) driver is keeping its old state before the bug happened, it's either in plugged or unplugged state by checking device manager in control panel

by stopping all virtualbox guest, usb device(s) become fine, VBoxSVC started by administrator is closed, but unexpectedly VBoxSVC started by moo account is still there, i can not kill it even with procexp

btw, i have vbox 4.0.2 installed correctly, extension pack is upgraded to 4.0.2
