Scanning Stops When Using NEC Open Host Controller and HP USB Scanner

ID: Q244594

The information in this article applies to:

Microsoft Windows 98
Microsoft Windows 98 Second Edition

SYMPTOMS

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.

CAUSE

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.
