Dear Mr. Karant,

I've just checked the membership list of the vbox-dev mailing list
but didn't find your E-mail address so it seems that you are not
subscribed to this list. Note that there was a vbox-users mailing
list until some months ago which does not longer exists. But I hereby
forward your E-mail to the vbox-dev mailing list.

On Thursday 10 June 2010, you wrote:

> devices and USB 1.1 cables with USB 1.1 devices. Swap cables and check the

> 2) Next, open Device Manager and look under the heading for USB Serial Bus

> A. Click on Start

> D. Click the Device Manager button.
> E. Expand Universal Serial Bus controllers section.
> F. Right-click every device under the Universal Serial Bus controllers
