VirtualBox doesn't recognize USB devices

VBoxManage list usbhost does not list and USB devices, lsusb does.

# VBoxManage list usbhost
Host USB Devices:


# lsusb
Bus 001 Device 001: ID 0000:0000
Bus 001 Device 002: ID 058f:6362 Alcor Micro Corp. Flash Card Reader/Writer
Bus 001 Device 005: ID 0bc2:5071 Seagate RSS LLC
Bus 002 Device 001: ID 0000:0000
Bus 002 Device 002: ID 093a:2500 Pixart Imaging, Inc. USB Optical Mouse
Bus 002 Device 003: ID 043d:010b Lexmark International, Inc. 2500 series
OS is CentOS 5.6 with latest updates.
VirtualBox is: VirtualBox-4.0-4.0.8_71778_rhel5-1
The Oracle_VM_VirtualBox_Extension_Pack is installed and the same version as VirtualBox.

# ls -ld /dev/vboxusb
drwxr-x--- 4 root vboxusers 80 Jun 13 02:20 /dev/vboxusb

I am running as root, and root is a member of vboxusers

Anybody have any ideas how to fix this?

VirtualBox doesn't recognize USB devices Reply to Thread

I tried what was suggested to add the two lines to /etc/fstab, but no difference.

The problem I am having is somewhat different than they were. mine returns none, theirs was giving them an error.

Any other suggestions?

Well I down graded to VirtualBox 4.0.6 and all works okay, no need to add any lines to /etc/fstab. Going back to 4.0.8 doesn't work even after I get /proc/bus/usb and /dev/bus/usb looking the same as under 4.0.6. Seems to be a problem with some of the routines VBoxManage uses, or VBoxManage itself.

Problem fix in 4.0.10

Upgrading to the recently released 4.0.10 version also fixes the problem.
