DOCUMENT:Q154711 07-SEP-2001 [winnt] TITLE :HP Scanners Not Detected by Deskscan Program PRODUCT :Microsoft Windows NT PROD/VER:4.0 OPER/SYS: KEYWORDS:kbprint kbPrinting ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Server version 4.0 - Microsoft Windows NT Workstation version 4.0 ------------------------------------------------------------------------------- SYMPTOMS ======== Hewlett-Packard (HP) scanners may not be detected properly by the Deskscan program when you are using a BusLogic BT-542b SCSI host adapter. CAUSE ===== This behavior occurs when you are connecting a HP scanner to a BusLogic SCSI host adapter with a BIOS firmware revision of 3.35/4.70. The HP scanner is properly detected with earlier versions of the BIOS. RESOLUTION ========== Contact either BusLogic for a possible BIOS upgrade or Hewlett-Packard for an updated version of Deskscan. MORE INFORMATION ================ After you start Deskscan, your computer may slow for 3-4 minutes before Deskscan finally appears and misreports the scanner as absent. If you attempt to test for the presence of the scanner, the computer slows again for 3-4 minutes. If you opt to view the SCSI address settings within Deskscan, a scanner is reported at all eight IDs, even when it and the adapter are the only devices on the bus. Regedt32 reports the situation properly. This behavior has been reported with the HP ScanJet IIp and IIc using the BusLogic BT-646s h/a (MCA card) adapter and also on a PowerPC using the BT-542B and BT-545S SCSI controllers. NOTE: The scanners on the Windows NT 4.0 Hardware Compatibility List were not tested on BusLogic controllers. These scanners are only supported if connected to one of the following SCSI controllers: AHA-1542CP, AHA-2742, and AHA-2940, NCR 8100S, and 8250S.
