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 ...

Eject removes the media from the device (e.g., ejects the CD tray) but doesn't remove the device itself. Safely Remove flushes any pending writes from the cache and removes the entire device.

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 ...

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 :)

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.

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 .

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 ...

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 ...

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.

Try VBoxManage controlvm usbattach <uuid>|<address> VBoxManage controlvm usbdetach <uuid>|<address> as described in manual.

Never mind, I finally had enough of the mouse and ended up throwing it against the wall hard enough to break it into pieces.

Here is example of SD card specification: http://www.transcend-info.com/products/spec.asp?Stype=Spec&ModNo=376&flag=showdetail Durability 10,000 insertion/removal cycles 7 years while you'll use it every day ( remove from camera, plug in to computer, remove from computer and plug in to camera ). And remember, you can buy another card, but you ...

The dark marks you see there are not actually scratches, but rather accreted dirt. You can usually wipe off the dirt and other patinas that tend to accumulate on metal with a soft, rubber pencil eraser. The contacts will be nice and shiny again and have electrical conductance that’s about as good as new. The lighter marks you see on a couple of those ...

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 ...

Go into the Bluetooth Devices section of your computer and configure it to connect to your keyboard and mouse. This may not be possible if your keyboard and mouse are ONLY configured to work via USB port.

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 ...

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 ...

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 :)

Well, there is no easy way to figure this one out. I think that intuition should work best. Basically, user should estimate how much data transfer device needs. So mice, keyboards and similar devices would work fine on USB 1.1 while HD webcams and others would need 2.0 for acceptable speed. I'd say that printers too need USB 2.0. I don't know if they ...

Keyboard, mouse, graphics tablet: 1.1 Anything that involved data transfer: 2.0/3.0

I found that you either love it or hate it. Personally I hate it. Split keyboards might be best ergonomically, but I haven't had any issues at all and much prefer a flat keyboard layout.

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 ...
