Visioneer has no tech support.
- and neither does it look like you can have a late version of the Visioneer
9220 USB scanner driver from their WEB site. However may you find useful
information regarding the USB problem on their Knowledge Database references:

and

PLEASE HELP! Thanks!
This “USB device stopped working for no apparent reason†is a recurring
issue in many Newsgroups, and apparently not always easily resolved. But of
course there IS a reason, if not always apparent. Two main sources for
causing the problem are change - / adding hardware and software (drivers) and
following conflicts as consequence.
It is difficult to give a precise advice on how to resolve your case, as
little information is available regarding the activities which took place
between the “ok - and not ok situationâ€, like adding hardware and/or software
e.g manual – or automatic updates etc. I would for a start unplug the scanner
and camera, and remove and reinstall USB controllers (preferably firstly the
camera and verify that it works) as per “General USB troubleshooting in
Windows XPâ€,

The drivers to reinstall should be the latest versions from Visioneer (if
obtainable, otherwise use as when first installed) and Logitech.
