When using a Hewlett-Packard (HP) ScanJet 6200C Universal Serial Bus (USB) scanner connected to a computer with an NEC Open Host Controller USB controller, you may suddenly be unable to perform a scan after having started or completed a scanning operation (such as a Preview scan). Also, the scanning software may be listed as Not Responding in the Close Program dialog box.


This problem occurs when the NEC Open Host Controller does not correctly acknowledge a USB packet which is smaller than the full packet size, and the HP ScanJet 6200C does not properly resend a packet that has not been acknowledged.
