USB to PS/2 Converter Cable Is Not Detected

USB to PS/2 Converter Cable Is Not Detected

There are two kinds of USB to PS/2 adapters: straight adapters and signal converters. Adapters are designed to approximate a PS/2 port as connected to the USB port, while signal converters have internal hardware that takes the PS/2 signal and turns it into a USB signal. The hardware in signal converters allows the BIOS access and may include operating system drivers, which can alleviate many issues that users encounter with PS/2 to USB adapters.

1). Turn off the computer and reconnect all USB and PS/2 devices. Ensure that the connections are all well-seated, and fit snugly into the ports.

2). Try using a different USB port. The same hardware may function differently in different USB ports for a few reasons, including a different power output, a dusty or dirty USB port, or hardware failure within the computer.

3). Ensure that your device(s) are plugged into the right ports. If your adapter is colored, the purple connector is for keyboards, and the green connector is for your mouse.

4). Connect the keyboard and/or mouse without an adapter to another computer to make sure that the keyboard and/or mouse is still functioning. If you don't have a computer with a ps/2 port to test the devices, you may try the adapter in another computer with USB ports.

5). Try another keyboard and/or mouse with the adapter. If the adapter works well in your computer with different hardware, this may indicate a compatibility issue between your adapter and style of keyboard and/or mouse.

6). Find out if your adapter is compatible with your devices. If you're using an adapter designed to be connected to both a keyboard and mouse, without using both devices, the adapter may not function properly. The manufacturer's website should include any relevant device conflicts.

How to Make an SCSI to USB Adaptor

How to Make an SCSI to USB Adaptor

SCSI stands for Small Computer Systems Interface. SCSI was the standard to connect most computer peripherals until the emergence of USB cables. Nowadays, a vast majority of computers are equipped with USB ports for peripheral connections. However, if you have a SCSI peripheral device, you may want to build a SCSI to USB adapter so you can use it on a computer with a USB port. Note that you will need a SCSI to USB cable and a USB cable to perform this task. These cables are available for purchase in most electronic stores.

1). Connect the "SCSI" end of a "SCSI to USB" cable to your SCSI peripheral device.

2). Connect a USB cable to the "USB" end of the "SCSI to USB" cable.

3). Connect the other end of the USB cable into one of the empty USB ports on your computer.

4). Turn on your SCSI peripheral device. Wait until your computer recognizes the device and let Windows install the necessary device drivers. Once connected, you will see a notification saying that the device is connected and ready to use.

Vesa VGA Connector

What Is a Vesa VGA Connector?

Cable clutter is a problem that can be frustrating and counterproductive when setting up a workspace. The VESA connector attempts to solve this problem by combining many different signals into one wire.

Background

1). VESA is an acronym for the Video Electronics Standards Association, which sets standards for PC and computing environments. The VESA connector is capable of incorporating video, audio, printer, Firewire and USB connections into one wire.

Central Connection Point

2). The monitor acts as the hub for all incoming hardware connections such as the mouse, keyboard and printer. The VESA connector directly connects the monitor to the PC hardware via a 34-pin MicroCross Molex pin and socket on both sides of the wire. This essentially eliminates the need to connect each individual device to the PC directly.

Evolution

3. The VESA connector was later renamed the VESA plug and display connector. Eventually, DVI replaced the VESA connector due to its ability to support high bandwidth and enforce digital content protection.

VESA VGA Monitor

What Is a VESA VGA Monitor?

VESA is a worldwide monitoring body for a variety of computer graphics standards. They're best known for Flat Display Mounting Interfaces (FDMI), which allow monitors to attach to walls. FDMI-compliant VGA monitors are known as VESA VGA Monitors.

VESA

VESA (Video Electronics Standard Association) was founded in the late 1980s by NEC and several other monitor manufacturers. It operates primarily as a trade group to maintain common benchmarks and standards for computer video technology. VESA's other best known standard is the Display Port benchmark for mobile computers.

Monitors

VESA monitors may have one of a number of mounting interfaces. The most popular by far have a pattern of holes that are either 3 inches by 3 inches or 3 inches by 4 inches. These holes are used to screw in mounts, which are then used to attach the monitor to a wall or other surface.

VGA

The VGA standard (Video Graphics Array) is a popular benchmark for computer graphics that was developed in the late 1980s. It is best known for blocky 640x480 pixel resolution and a relatively large color palate. Although VGA is not the most popular video standard anymore, it's often used for mobile devices and specialty computers in the sciences.

General Components of a PDA

The General Components of a PDA

The use of personal digital assistants, or PDAs, as an electronic tool for organization started in the mid-1990s. Early models had expansion slots, which you could use to connect to external modems and cameras. In 2010, with numerous cell phone networks available, PDAs are nearly interchangeable with smart phones, and they share several general components.

Communication

PDAs offer many communication choices. You can develop a contact list that contains names, addresses, emails, phone numbers and special dates that link to the calendar (such as birthdays and anniversaries). From that contact list, you can make phone calls, send text messages or prepare emails. You also can place phone calls directly, either with a phone pad or voice commands.

Cell phone providers also provide internet connectivity. This allows for web browsing and the continuous ("push email") receiving of emails from your email provider.

Organizers: Calendars, Task Lists, Notes & Memos

PDAs provide different ways for organizing time. Calendars provide daily, week, monthly and specialized views and many can be synced with other PDAs or PC-based programs. Task lists provide due dates (which can appear on calendars), status checks, reminders and repeat indicators. You also can take notes on the go with general notes pages, which you can name and categorize.

Input Functionality

You can input information with a touch screen, stylus or your thumbs using a QWERTY style keyboard; some offer a combination of options. The keyboards can be physical (some may slide down for use) or virtual (accessed from a touch screen).

Media & Storage

Most PDAs provide internal digital cameras, video cameras and voice note recorders for taking and playing photos, video clips, voice notes and music. You can add to the internal memory with memory cards, and you can download your media files to your computer (for editing and storage) and to online websites for sharing.

Functions & Programs

Many PDAs offer pre-loaded functions, such as alarms, calculators or mobile versions of Microsoft Word, Excel or PowerPoint. You can activate navigation systems using GPS technology. Applications (or "apps") are popular, and PDAs can download apps that cover a variety of subjects and interests, from personal finance, gaming, education, business, entertainment, music, social networking, health and more.

How to fix Keyboard not detected by the computer:

When you use a wired keyboard, you may experience one or more of the following problems:

• The keyboard is not detected.
• The keys on the keyboard do not work.
• Wrong characters are typed.
• The keyboard shortcuts do not work.

To work around keyboard is not detected, use the following methods

1.      Turn off your computer before troubleshooting. Verify that the keyboard is securely plugged in to your computer. Try another PS/2 or USB port if your computer has more than one, or try the connections on another computer, if applicable. If the keyboard  still doesn't work, then it may be defective and needs to be replaced.

2.      Confirm that the driver software was installed correctly by checking whether there is any error next to keyboard entry in device manager. Some keyboards, especially if they're wireless, require drivers in order to function properly. Also follow the instructions to install any software that came with the keyboard.

3.      Update the driver for your keyboard, if necessary. Open the control panel on your computer, check the hardware settings and then follow the commands to update the driver.

4.      Turn the keyboard upside down to remove any dust, debris or food crumbs. These particles can also prevent the keyboard from working properly. Clean out hard-to-reach areas of the keyboard with an air compressor or a "static-safe" vacuum cleaner.

5.      Fix the keyboard layout if the characters on screen don't match what you type. Select an input language on your computer, then choose the keyboard layout that matches that language from control panel( region and language settings)
