Mcci SCSI & RAID Devices Driver Download

Hello everyone, I'm new to this site, and somewhat of a computer novice. Lately my computer has been making a beep when typing on email, web search engines, or even Word. Once it beeps, the keyboard either stops working, or more often it begins typing lots of characters on its own. Once this happen. MCCI is the world’s leading developer of software supporting USB connectivity in PCs and embedded systems. From products to service, we’re here for you.

Goodbye, installation frustrations! InstallRight Pro automatically ensures a proper driver installation for a more user-friendly experience.

InstallRight Pro prepares Windows to automatically set up a new device. Even with the Windows Plug-and-Play infrastructure, loading appropriate drivers for a device can be confusing for novice users. Worse yet, users are sometimes presented with options that result in an unusable driver installation. Recovery from an incorrect installation is often quite complex and frustrating.

Using InstallRight Pro

MCCI InstallRight Pro makes installation of device drivers more predictable, user-friendly, and controllable.

InstallRight Pro automatically insures a proper driver installation. MCCI InstallRight Pro is called by the Windows Device Manager when a new Plug-and-Play device is detected.

After the installation, InstallRight Pro communicates with the operating system to insure that devices are correctly installed.

The InstallRight Pro uninstaller makes recovery from a failed or incorrect driver installation simple. It uses the relevant INF files to identify all driver files that need to be removed and after removing those files, it also removes the associated registry entries. Finally, it schedules deletion of itself on the next reboot.

InstallRight Pro has two components:

  • A customer branded setup.exe, which can be used either to install driver components at device plug-in or to pre-install driver components before the device is attached.
  • A branded uninstall.exe, which can be invoked using Add/Remove programs.

If InstallRight Pro encounters any problems, it displays a detailed message. Users of older operating systems will no longer wonder why a device that requires a newer operating system doesn’t install.

InstallRight Pro functionality can be integrated into the installation procedure for another program, such as an application for a device, so that the drivers and the application can be installed or uninstalled together. It can also function as a standalone software installer or it can easily be bundled with other drivers for downloading. Optionally, it can be supplied on a distribution CD-ROM.

InstallRight Pro handles the Plug-and-Play system differences between various Windows versions, including Windows XP, Vista, Windows 7, and Windows 8.

Load Device Drivers at Product Attach

You can install USB host drivers directly from your product, saving the cost of shipping the drivers on an installation CD-ROM. InstallRight Pro facilitates straight-forward installation and pre-installation scenarios, but it can also accommodate an extraordinary amount of behind-the-scenes customization. Your product can initially present itself as a USB composite device with a single Mass Storage Class (MSC) interface. InstallRight Pro can use this interface to load a configuration customized for the features your product brings to market. After driver installation, the device subsequently presents itself with its full functionality. Here’s what happens after the user connects the device via USB cable to the Windows system:

Class descriptors from the phone force the MSC device driver to load. At that point, InstallRight Pro is called by the Windows autorun.inf file. InstallRight Pro pre-installs the MCCI bus drivers and function drivers, updates the current instance of the MSC driver, and changes the registry. Then it encapsulates and sends a custom SCSI command via BOT. After that InstallRight Pro exits.

At this point, the device initiates a soft-disconnect by disabling the D+ pull-ups, which unloads the driver. Immediately afterwards, the device initiates a soft-connect and is re-enumerated. At enumeration it is automatically recognized as a composite device and the pre-installed custom drivers are loaded. Full device functionality is now available to the user.

USB Mass Storage

My book USB Mass Storage: Designing and Programming Devices and Embedded Hosts will be available soon.

Basics

The USB mass-storage class encompasses devices that transfer files in one or both directions. Typical devices are floppy, hard, CD, DVD, and Flash drives. Cameras can use the mass-storage class to enable accessing picture files in a camera’s memory. In Windows computers, devices that use the mass-storage driver typically are formatted with a file system that Windows understands and appear as drives in My Computer. The file system enables users to copy, move, and delete files in the devices.

Almost all USB mass-storage devices use the bulk-only transport (BOT, also called BBB) protocol defined by the USB mass-storage class specification. (An exception is some full-speed floppy drives, which use the control, bulk, interrupt (CBI) protocol.) USB mass-storage devices also use SCSI commands defined by various SCSI standards.

The SCSI command sets specify a protocol for transferring blocks of data and status and control information such as a device's capacity and readiness to exchange data. Devices with USB and other hardware interfaces can use the SCSI command sets.

The mass-storage bulk-only protocol defines how a USB host can send commands and receive responses using the bulk transfers defined by the USB specification. In the bulk-only protocol, each exchange of information requires two or three USB transfers. In the first transfer, the host sends a command in a structure called a Command Block Wrapper (CBW). Many CBWs are followed by a transfer that contains data sent to the host or device. In the final transfer, the device returns status in a structure called a Command Status Wrapper (CSW).

File Systems

Mass-storage devices typically store data in files. An operating system can format a USB mass-storage device to use any of a number of file systems, such as FAT32, FAT16, and NTFS. In a Windows system, a formatted mass-storage device appears as a drive in My Computer, and users can read and write files in the same way they access files on other system drives.

For many mass-storage devices, including hard drives and flash drives, the sole purpose of the device is to enable the host to store and retrieve files. For these devices, the device firmware doesn't have to know or care what file system the host is using. The firmware just stores and sends blocks of data as requested by the host.

Other devices require firmware support for a file system. For example, a still-image camera might store its images as files. When the camera connects to a host computer, the camera appears as a system drive, making it easy for users to access the images. Or a.

Wear Leveling

Flash memory is a popular choice for smaller drives. Flash memory can withstand a limited number of erase/write cycles, however. A typical guaranteed number of cycles for the NAND memory used in storage devices is 100,000. Firmware that repeatedly writes to the same addresses will quickly wear out that portion of the memory. To extend the life of a flash-memory chip, firmware can implement wear leveling, which uses various techniques to access all areas of the memory more equally.
