9298	Win7 USB error ==> Fixed in SVN	Nathan		"I upgraded from VirtualBox 4.0.x (latest version of 4.0 series) to the latest version of 4.1 on Windows 7 Ultimate x64. When I go into any VirtualBox machine settings, I get and error window that says:

----

Failed to access the USB subsystem.

Could not load the Host USB Proxy Service
(VERR_FILE_NOT_FOUND). The service might not be
installed on the host computer.

ResultCode: E_FAIL (0x00004005)

Component: Host

Interface: IHost {dab4a2b8-c735-4f0894fc9bec84182e2f}

Callee: IMachine {5eaa9319-62fc-4b0a-843c-0cb1940f8a91}

This happens every time I try to enter any settings, even while the machine is running. I have a forum thread at [http://forums.virtualbox.org/viewtopic.php?f=6&t=43341&p=194903#p194903] and a screenshot of the error at [http://dl.dropbox.com/u/16149550/CPU/ScreenShot001.png]

I can provide more information if needed.

Here's a link to the only VBox.log that may have some info, because the error only shows up either when I'm entering VirtualBox machine settings before I start it, or when I enter the settings while the machine is running. I don't know if it'll have any info, but here it is:
