This isnt an unbreakable rule. The main reason to install drivers first is that the device manufacturer knows the drivers did not ship with Windows XP (or whichever OS). You can certainly plug the device in and the world will not implode in a cataclysm of fire. Typically, Windows will complain that it doesnt know what the device is and prompts you to ...

Maybe because plugging it in first might result in some default driver getting installed which lacks the options (bloat?) the recommended driver package offers. This is not only likely to confuse a normal user, it is then going to be extra confusing/difficult to teach him/her how to update the driver to the recommended one (resulting in lots of unnecessary ...

Laser and optical mice essentially take hundreds of photos every second. They compare successive images to find a common point between them, and from that common point, calculate x and y offsets to send to the computer. The laser or LED merely act as a light source. Of course this is a vast over simplification. There are a couple of methods for ...

Is one of those types of KVM switches better than the other in any way? Depends what you want to do, but for the most part they are equal. I often use a USB adapter on my PS/2 KVM switches with no problem. In most modern computers that still have ps2 ports, the PS/2 bus is actually part of the USB bus. ---EDIT--- After doing some more research found ...

It causes more work, but the amount is so small that it is not significant to slow down your laptop. Let's see some examples: A USB or PS/2 Mouse The mouse is being polled at a constant rate to determine whether it has moved or clicked, these polls don't take much CPU cycles so you will not notice any difference by connecting a mouse to your computer. An ...

How about a wireless mouse and the Volumouse program from Nirsoft? With it you can set the scroll wheel to change volume when either no key is pressed, or when some media players are focused. EDIT: Just noticed that this is similar to Moab's wireless mouse with AutoHotKey answer, just using a different application.

I ended up shutting off the computer (actually, just sleeping it, but you could try shutting it off). With the computer off I plugged in the joystick, started it up, and Windows 8 found the joystick, installed the correct drivers, and I was good to go. Screenshot of the joystick recognized in Windows 8:

You will need someone (or yourself) to develop a software for this purpose. Basically you will need to capture the barcode input, use ShellExecute API to launch the web browser, and use the SendMessage API to send the text into the browser form field. For help on programming you may try stackoverflow.com :)

See this article http://www.instructables.com/id/Remote-Volume-Control-with-Wireless-Mouse/ EDIT: xmouse is another option, it can intercept any mouse button and reassign volume up down to that button also http://www.highrez.co.uk/downloads/XMouseButtonControl.htm .

If you don't mind writing a few lines of code then have a look at the Arduino it's got 6 (depending on the model) analog inputs as well as a load of DIO's and a USB connector that acts as a serial port. Writing code for it is really simple and theirs lots of examples on the web site. It's a great device and really fun to play with. Price is good as well, ...

The reason that the mouse does this is because it enters sleep mode when it stops moving, it seems that in your case the timer is affected which makes it enter sleep mode way too fast. For the device to return from sleep mode it has to reconnect Bluetooth, which can indeed take 5-10 seconds. Take the warranty road, or send it in for a repair. But it seems ...

I haven't actually tried this myself, but from the research I have done on the topic (to accomplish exactly the same thing as you), you will need: A USB hub which supports "per-port power switching" - not many support this A utility to actually toggle the power Take a look at http://www.gniibe.org/development/ac-power-control-by-USB-hub/index, he is ...

In most cases, USB accessories like fans and lights aren't real USB devices - they just want a little bit of 5v power. The way USB works for real devices is that they get a little bit of power to start, enough for them to turn on. Then they enumerate with the USB controller and request more power. Since these fake USB devices aren't actually talking to ...

During the time of Windows 98 there was only one option Eject. Any USB device like pen drive required that the driver for that device be manually installed. To remove the device you had to select Eject from the context menu. Since Windows XP the driver gets automatically installed and a new improved feature is provided to remove the USB device which is ...

I have a multi-meter that I got at Radio Shack a couple of years back. It's their catalog #22-812. Among all it's measurements, it also has a serial port that can be used for data logging. Get a cheap serial-to-usb adapter, and program away to your heart's content. Obviously the date collection rate will be somewhat limited, as this is a dmm, not a scope. ...

Try using http://www.nirsoft.net/utils/usbdeview.zip. This executable displays all USB devices attached to your computer and allows you to disconnect them individually as required. As noted from the read me: USBDeview is a small utility that lists all USB devices that currently connected to your computer, as well as all USB devices that you ...

You can try adding i8042.nokbd to the GRUB boot line to disable access to the keyboard controller at boot. It is possible to turn off the keyboard via 8042 commands without rebooting, but it's not really safe to do so; on some systems, this interferes with the memory management and causes a nasty system halt.

Apparently you could use e.g. Apple's Bluetooth keyboard, albeit only with a jailbroken iPhone. See video: http://www.tuaw.com/2009/02/23/apple-bluetooth-keyboard-paired-with-iphone/ Another one, with no jailbreaking needed: http://www.tuaw.com/2009/03/24/iphone-external-keyboard-without-jailbreaking/ It doesn't seem very attractive solution though :)

USB means the ultimate in simplicity and versatility. Print quickly - without using a PC - by connecting any PictBridge™ camera or phone directly to the printer. You can also connect USB memory to the printer and print instantly. Even when you don’t have access to a PC, you can save what you scanned directly to a USB memory. Quote from ...

There are plenty, google for "USB selector", here is one example USB 2.0 KVM 2 Port Ports Selector VGA Print Switch Box But I think you really should use Synergy instead. Synergy lets you easily share a single mouse and keyboard between multiple computers with different operating systems, each with its own display, without special hardware. It's ...

I can use the Windows volume slider or any keyboard with keys to control volume. There's your answer. You want a wireless keyboard. Get a bluetooth model for improved range. You might also look into a media center remote or a logitech harmony.

It depends on the hardware. In general, these days, the answer is no. Even in the way back when, it was all a bit of a beat-up. It used to be the case before multisync monitors that you needed to match monitor and video card - if they were wrong then the monitor would not sync. (Video signals in particular are all over the place, depending on resolution ...

What kind of battery are they? And did you charge them, or do you just assume they're charged when you buy them? This is why I ask: NiMH and NiCd batteries self discharge at a MUCH faster rate than alkaline batteries. In fact, at "room temperature" (about 70 degrees F) NiMH and NiCD batteries will self discharge a few percent PER DAY. Storing them at ...

Don't buy that particular scanner-- it doesn't support 2D barcodes. Does the computer you plan to use for this have a webcam? Because that might be a totally acceptable scanner for this purpose. Then you could use software such as http://blog.odoa.eu/post/QR-Code-Scanner-for-Desktop-and-Laptop.aspx to do what you want. (I tested this. It's clearly a ...

If this is the Microsoft Natural Ergonomic Desktop 7000 wireless keyboard+mouse set, apparently it does not support Bluetooth — the “2.4-GHz Wireless Technology” is a proprietary interface not compatible with anything else (except maybe other similar Microsoft wireless hardware). This is a very common situation — finding a wireless keyboard or mouse which ...

When a CPU talks to a memory address, it isn't RAM that has to respond. It can be an I/O device. You can actually think of RAM as a "specialized memory-mapped I/O device" whose job is just to save and give back data, although with today's modern CPUs that have caching and such, it's not physically straightforward. I am not too keen in the low level ...

The short answer is no. To steal from @Sickest and the link in his comment and elaborate: That image you provided is outdated. Modern architecture actually moved the memory controller from the North Bridge to directly on the CPU. And if you ever look at your motherboard, you will see many controllers and chips that peripherals must communicate with ...

After investigating the subject, it turns out that most USB KVM switches are just electrical contact switches, which means when you press the button, the USB devices are electrically disconnected from one PC and connected to the other, and so there is a big delay in the switching due to Windows detecting the devices. If you google for "USB kvm delay" you ...
