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.
