This is the error message that came up - has anybody any ideas
Could not load the Host USB Proxy Service (VERR_FILE_NOT_FOUND). The service might be not installed on the host computer.
Result Code:
NS_ERROR_FAILURE (0x00004005)
Component: host
Interface: IHost {f39438d7-abfd-409b-bc80-5f5291d92897}
I am just reinstalling the complete system, I had Virtual Box running on my last installation and I still have the same problem where it will not recognize
my printer in the WindowsXP operating system that I had installed. Thank you in advance for any help! I have decided that I am staying with Linux to the end now.
Regards
Barry Sinclair

Did you already try to modify /etc/fstab and reboot your system?
Add the following line to your /etc/fstab:
Code: Select all
none /proc/bus/usb usbfs devgid=128,devmode=664 0 0
Good luck!

Usb support rely on a kernel feature which is now deprecated. So you it might not compiled into your kernel. If you don't see /proc/bus/usb direcory even with root user, check your kernel config and recompile with this option if missing:
Code: Select all
Location:
-> Device Drivers
-> USB support (USB_SUPPORT)
-> Support for Host-side USB
-> USB device filesystem (DEPRECATED)
Because it's deprecated, I hope this dependency will get dropped.

You RTFM guys are really useless; this is not documented in the manual. This is a problem with USB host on windows that happens during upgrades where the rights of the user installing the VBox and rights of the user installing extensions do not match (since in windows you can install VBox using elevated rights but extensions require admin to log in to execute and thus creating a strange permissions issue). Best way is to do this with user that had admin rights but that is not always possible in environments where IT will not allow admin user rights.
If your host system is Windows (Win 7 64bit in my case) then what worked for me is to make sure your user has admin rights to the machine during the whole install and when upgrading to newer version.
As administrator:
Uninstall Vbox.
Manually delete the VirtualBox extensions directory but do NOT remove the virtual machines directory.
Reinstall VirtualBox and reinstall Extensions.
Start VirtualBox and reset all the machines to be powered off (i.e. delete the saved state, if they weren't already).
That fixed it for me, everything works fine and no errors anymore.

And correct!
Perhaps RTFM in this case stands for 'Read The Frak'n Message'
Thanks Achacha ...

Or perhaps even read the thread? Note that the RTFM comment was made in 2008, and consider what might have changed since then. For example, that Win7 didn't exist.
Locking this thread, since I can't see anything useful being added.
