All was working fine until I installed an Owncloud client (OwnCloud version 2.1.1 Using Qt 4.8.6)
As soon as the onwcloud client is running on the host, no usb device are found in the virtualbox. The issue can be simply revealed by using VBoxManage:
Code: Select all
xxx:~$ VBoxManage list usbhost
Host USB Devices:
<none>- with Owncloud client running, root user: all USB devices listed
- with Owncloud client running, non root user: no USB ldevices found
- without Owncloud client running, root user: all USB devices listed
- without Owncloud client running, non root user: all USB devices listed
Additionnally, I found that if VirtualBox is launched before Owncloud client, everything works fine!
I was first suspecting an permission issue so that I recheck that I was in the vboxusers group, I tested different rules found here and there (60-vboxdrv.rules, virtualbox.rules), uninstall an reinstalled virtualbox and extensions (3 times), rebooting each time. The result was invariant: my guests are running but USD devices are not available when Owncloud client is running.
I don't know if this should be reported as a bug. If someone as any idea to correct this issue, I can make additionnal tests.
