Ticket #6684 (closed defect: obsolete)
usbfs used by VB process fills syslog after suspend-resume of host (until disk full!)

Description (last modified by aeichner) (diff)
I use VirtualBox 3.1.8 (non-OSE) on a laptop host (HP Compaq nx8220) under Ubuntu 9.10. And I run Ubuntu 10.04 as client OS.
When I connect the USB device "Bluetooth adapter" to the client, everything works as expected. But after suspend-resume of the host the VB process begins to fill /var/log/kern.log, /var/log/syslog and /var/log/messages of the host with lines saying:
oliverhp kernel: [ 1232.854921] usb 3-2: usbfs: process 4918 (VirtualBox) did not claim interface 0 before
When I measured, there were about 23 lines per second in each of the 3 logfiles (about 500 kB/min). But the bug got detected after it filled about 300 MB in less than 2 hours until the root partition was full! So I dare to mark this bug as critical. But as not so many people are affected, I won't mind to lower its priority.
Affected USB device:
# lsusb Bus 003 Device 002: ID 03f0:011d Hewlett-Packard Integrated Bluetooth Module
usbfs in /etc/fstab:
# cat /etc/fstab none /proc/bus/usb usbfs defaults,devgid=46,devmode=666,nodev,nosuid,noexec 0 0
I have no other suspend-resume problems with my host when VB is not running. No wonder because VB is probably the only application which uses usbfs on my system.
