Could not load the Host USB Proxy service: VERR_NOT_FOUND -> setup issue

Reported by: WBryan Owned by:
Priority: major Component: USB
Version: VirtualBox 4.0.12 Keywords: VERR_NOT_FOUND USB Host Proxy
Cc: Guest type: Linux
Host type: Linux

Description

USB not working with my Linux host using VB 4.0.12-72916.

I have the updated extensions pack installed (version matches current VB version). My user is in the vboxusers group (and has logged out and back in again).

USB was working with the same user and settings using VB 4.0.9.

Here's the error box message that appears when I click on "Settings" for the Client machine in the GUI:

Failed to access the USB subsystem.
Could not load the Host USB Proxy service: VERR_NOT_FOUND.

Result Code: 
NS_ERROR_FAILURE (0x00004005)
Component: Host
Interface: IHost {35b004f4-7806-4009-bfa8-d1308adba7e5}
Callee: IMachine {662c175e-a69d-40b8-a77a-1d719d0ab062}

My host machine: 64bit SMP RHEL5.7 (kernel 2.6.18-274.el5).

I'm hopeful that this isn't a dup of another ticket... I didn't see any with the same "VERR_NOT_FOUND" and "Host USB Proxy".

Could you please provide the output of

$ VBoxManage list usbhost

executed as the user running VirtualBox and

# ls -lR /dev/vboxusb

executed as root?

"Appears" to be a permissions problem... but I'm not sure why this popped up on an update.

comment:3 Changed 3 years ago by michael

The permissions on the device nodes under /dev/vboxusb look correct to me. Could you try another test? Stop all VirtualBox and VBoxSVC processes, run (as user)

$ strace -o VBoxSVC.out -f /usr/lib/virtualbox/VBoxSVC

then in a different terminal (again as user)

$ VBoxManage list usbhost

and finally stop VBoxSVC and attach the VBoxSVC.out log file to this ticket. Thanks.

Attached requested output. It's been gzipped because of the file size limit in this bug tracker.

You don't have any VBOX_USB settings in your environment by any chance do you?

comment:6 Changed 3 years ago by WBryan

Dah... I do.

VBOX_USB=usbfs

This was an apparent "fix" from a previous version. I'll try NOT setting this variable..

comment:7 Changed 3 years ago by WBryan

Unsetting this environment variable (a fix from 4.0.8?), did the trick.

Thanks for your help.
