Windows 7 drivers. Windows 7 is an operating system of Windows NT family which was released after Windows Vista but before Windows 8. According to the data on summer of 2017, Windows 7 is the most popular operating system in the world. According to the data on July, 2017, Windows 7 is used on 48.91% of all PCs worldwide. When you plug the device into your USB, Windows will look for the associated driver, if it cannot find this driver then you will be prompted to insert the driver disc that came with your device. Common USB Device errors are ‘ usb port not working ‘, ‘device descriptor request failed error’ or ‘bugcodeusbdriver’ issues. Storport Driver.; 2 minutes to read; l; In this article. In addition to the SCSI Port driver, Microsoft Windows Server 2003 and later versions provide Storport (storport.sys), a storage port driver that is especially suitable for use with high-performance buses, such as fibre channel buses, and RAID adapters.

There are differences from version to version in the type of joystick support that Microsoft DirectX offers. In Windows 95/98/Me, DirectX supports two methods to customize joystick capabilities: through custom entries in the Windows registry and through a virtual device driver (VxD) creation, which is called as joystick minidriver. The minidrivers that are used in DirectX versions 1.0, 2.0, and 3.0 support the original minidriver interface, with minor differences in the DirectX 3.0 interface. In addition to the original minidriver model, DirectX versions 5.0, and later, include an alternative driver interface that is generally described separately.
Windows 95/98/Me joystick driver and configuration programs support analog joysticks that plug into the IBM standard game port. Joystick makers can make the joystick configuration programs customizable and provide explicit directions to the end user on how to customize the joystick. Joysticks can signal Windows 95/98/Me about their capabilities through the registry. These capabilities can include the use of throttle, point-of-view (POV) hats, rudders, and the number of joystick buttons.
All non-IBM standard joysticks, such as digital joysticks, MIDI joysticks, and analog joysticks driven by joystick accelerators must provide a joystick minidriver in addition to custom registry information. A joystick OEM can write a minidriver that provides access to nonstandard joystick hardware. This provides a mechanism for digital joysticks to work with any Windows-based game that uses the joystick application programming interface (API).
The driver model can deal with up to six axes, a POV hat, and a double word of buttons, so that an OEM can easily create a minidriver for new hardware with a higher degree of freedom than the current game port allows. The joystick minidriver provides complete flexibility to hardware vendors and allows game creators to use the installed base with their titles. In DirectX 5.0 and later, analog joystick support is also separated into a minidriver that uses a new interface. This new interface is loaded only when an analog game port is configured. The polling is extended with three extra POV hats, three more double words that contains button data, and a method to specify that it returns the velocity, acceleration, and/or force data for each axis.
The current virtual joystick driver (VJoyD) allows the configuration of up to 16 devices, any number of which can be driven by minidrivers. The configuration of minidrivers to devices can be one to one or one to many.

In addition to the SCSI Port driver, Microsoft Windows Server 2003 and later versions provide Storport (storport.sys), a storage port driver that is especially suitable for use with high-performance buses, such as fibre channel buses, and RAID adapters.
There are several advantages to using Storport rather than the SCSI Port driver:
Improved performance, both in terms of throughput and the system resources that are utilized.
Improved miniport driver interface that addresses the needs of high-end storage vendors, particularly host-based RAID and fibre channel vendors.
All vendors are encouraged to use Storport where possible, rather than the SCSI Port driver. Certain restrictions apply, however. Storport cannot be used with adapters or devices that do not support Plug and Play. All DMA devices must have bus-mastering DMA capability, because Storport does not support programmed I/O or subordinate-mode DMA. Other restrictions apply in regard to tagged queuing, autorequest sense, WMI support, the sort of SCSI inquiry data that devices must report, and booting directly from an adapter's ROM BIOS. For a detailed list of restrictions on the use of the Storport driver, see Requirements for Using Storport with an Adapter.

To better utilize the investment that vendors have made in SCSI Port miniport drivers, Storport follows the SCSI Port-miniport driver architecture with very few modifications. Changes to the SCSI Port driver interface were made in areas where new algorithms were able to produce measurable speed increases, or where it was necessary to add support for high-speed buses.
