SCSI Devices May Not Be Enumerated Correctly

 * }

Q155729

-

The information in this article applies to:


 * Microsoft Windows 95

SYMPTOMS
SCSI devices may not be enumerated correctly, especially when there are multiple buses upon which the devices may be located. Configuration Manager may not display SCSI devices that are installed.

CAUSE
There is a problem in the Scsiport.pdr file, in which the bus number is not correctly reported to the dependent miniport drivers. Instead, Scsiport.pdr always reports a bus number of 0.

RESOLUTION
This issue is resolved by the following updated file for Windows 95, and later versions of this file:

  SCSIPORT.PDR  version 4.00.951  dated 10/26/95  23,165 bytes
