After you have Windows booted you can try to unplug the USB drive and plug it back in or unplug it with the guest OS powered off and then plug it back in when it is on so the guest gets focus again. (be sure to cross fingers and turn around twice this time, it works for me Sacred dances are so old school).
Ok let's go at this a little differently.
First is this USB device active in the HOST?
Secondly remove any defined USB filters in the guest once you are sure that the device works in the Host.
Then start the guest and click on the device tab then select the USB device in USB and see if it energizes.

Yes. Shoudn't id be? I think I tried it inactive.

It works in the host. It didn't energize. Same message.
I assume you are shutting down the guest and not saving the state, would I be correct?
So what if you completely turn off the USB for the guest and then boot into the Windows. Let it settle down and then shut down Windows.
Then enable the USB again, start Windows and see if it returns.

Yes shutting down.

You mean deleting the filter from the vbox host interface? It is already deleted. Tried with and without filter. And then shutting the guest down? I think I don't understand.

Actually I meant to take the check mark out of the enable usb in the guest settings.
Somehow as you say there must be something hung that is keeping this from working again.
Frankly this is the first time I have ever seen this happen and just throwing things out there for you to try.
Also you can look in the machine folder and the name of the guest and see if the *.XML has any setting that looks out of place.
I was facing this problem since very long now but I solved it today so wanted to share the solution here.
What I did was to just disable USB 2.0 (EHCI) support in BIOS and then everything works...NO PROBLEMS at all!!!
I don't know why Virtualbox can't handle USB 2.0 but at least my scanner works now

That worked for me too. What Host are you running? Mine is Windows 7 64 Bit Ultimate RTM 7100
