Windows device driver information for Generic DVD-ROM SCSI CD-ROM Device. Generic DVD-ROM SCSI CD-ROM Device is an internal drive that has the capacity of 256 kilobytes with flash ROM since it is a ROM type. This drive provides reliability, performance and impressive. Description: HostRAID driver v1.5.11999.1 for the Serial ATA II RAID 1420SA and 1430SA using BIOS Build 2507. Installation Instruction: Installation instructions can be found in the User's Guide available on the CD that was included with the product or as a download from the Documentation section. Generic SCSI lets a virtual machine run any SCSI device that is supported by the guest operating system in the virtual machine. Generic SCSI gives the guest operating system direct access to SCSI devices connected to the host, such as scanners and tape drives. Generic SCSI on a Windows Host Operating System. Oct 30, 2016 Wondering if anyone can point out how I can restore my portable hard drive back to a generic USB mass storage device instead of being a 'USB attached SCSI mass storage device'. This thread is locked. This document outlines the Linux SCSI Generic (sg) driver interface as found in the 2.4 series kernels. The driver's purpose is to allow SCSI commands to be sent directly to SCSI devices. The responses of those commands can then be obtained. This type of driver is sometimes termed as a 'pass through'.

Starting with Windows 2000, the operating system provides native support for many USB mass storage devices. The Usbstor.inf installation file contains device IDs for those devices that are explicitly supported. If the USB hub driver enumerates one of these devices, the operating system will automatically load the USB storage port driver, Usbstor.sys.

The device IDs for USB mass storage devices in Usbstor.inf take the usual form for USB device IDs composed by using information in the USB device's device descriptor:

USBVID_v(4)&PID_d(4)&REV_r(4)

Where:

• v(4) is the 4-digit vendor code that the USB committee assigns to the vendor.

• d(4) is the 4-digit product code that the vendor assigns to the device.

• r(4) is the revision code.

In addition to these device IDs, Usbstor.inf contains compatible IDs for class 8 ATAPI CD-ROM and removable media devices that support bulk-only transport:

USBCLASS_08&SUBCLASS_02&PROT_50

USBCLASS_08&SUBCLASS_05&PROT_50

USBCLASS_08&SUBCLASS_06&PROT_50

Where:

• class 08h = mass storage devices.

• subclass 02h = SFF-8020i ATAPI CD-ROM devices.

• subclass 05h = SFF-8070i ATAPI removable media.

• subclass 06h = generic SCSI media.

• protocol 50h = the bulk-only transport protocol.

If the data retrieved from the device's device descriptor matches any of these compatible IDs, the operating system will load Usbstor.sys.

As soon as it is loaded, the USB storage port driver creates a new PDO for each of the device's logical units. For more information, see the example device stack created by Usbstor.sys illustrated in Device Object Example for a USB Mass Storage Device.

When the PnP manager queries for the device identification strings of the newly created PDOs, the USB storage port driver creates a new set of device, hardware and compatible IDs derived from the device's SCSI inquiry data. The device ID format is as follows:

USBSTORv(8)p(16)r(4)

Where:

• v(8) is an 8-character vendor identifier.

• p(16) is a 16-character product identifier.

• r(4) is a 4-character revision level value.

An example of a device ID for a disk drive would be as follows:

USBSTORSEAGATE_ST39102LW_______0004

The hardware IDs that the USB storage port driver generates are as follows:

USBSTORt*v(8)p(16)r(4)

USBSTORt*v(8)p(16)

USBSTORt*v(8)

USBSTORv(8)p(16)r(1)

v(8)p(16)r(1)

USBSTORGenericTypeString

GenericTypeString

Where:

• t* is a SCSI device type code of variable length.

• v(8) is an 8-character vendor identifier.

• p(16) is a 16-character product identifier.

• r(4) is a 4-character revision level value. In these additional identifiers, r(1) represents just the first character of the revision identifier.

The following table contains the SCSI device type codes used by the USB storage port driver to generate identifier strings.

These examples show the hardware IDs that are generated by the USB storage port driver:

USBSTORDiskSEAGATE_ST39102LW_______0004

USBSTORDiskSEAGATE_ST39102LW_______

USBSTORDiskSEAGATE_

USBSTORSEAGATE_ST39102LW_______0

The USB storage port driver generates two compatible IDs.
