How do I set up a d-link dub-h4 to my laptop I have a power connection, a connection on the rear of the hub-4 going to an adapter connecting to the ps/2 connector on the laptop. Do I need one of the...

The connection on the rear of the hub should go to a USB connection on the laptop, not a PS/2 connection. A PS/2 to USB adapter is used to connect a PS/2 keyboard or mouse to a USB connection.

Usb not recognizing device t2882

Hi,
What I suspect here is that,
Provided the operating system that you are using is Up to Date (e.g WinXP SP2 to Win Vista),

the USB port that you are using might be a USB 1.0 port, which has a lower voltage not enough to power on your Storage drive.

In this case, there are two things you can do,

1. Change the USB port you are using for the storage drive to a USB 2.0 one (Just keep Checking all the ports one by one in case you dont know which one it is).

2. If your Storage drive has external power facility, just plug it in an external power first, before connecting it to the system.

If there are no USB 2.0 Ports on your system at all,

then just go to any electronic store and tell them you want to buy a USB 2.0 Expansion card.

and if it is a laptop, A USB 2.0 PCMCIA card.

Install it on your system, and connect your external drive through it.

Hope this helps you out.

Goodluck

Ps2 port doesn't recognize Microsoft Optical mouse

You might think about a USB hub for all your USB devices. ps2 port is more or less dedicated for mouse, which is why your mouse pointer is stuck in the middle of the screen. Go ahead and get an externally powered USB Hub to power other USB devices. To answer, ps2 for mouse needs just a mouse, not USB device.

My computor switches off the moment i plug in the wd passport.

Probably a power issue. Your new computer has less extra power capacity and the external drive is pulling from the USB port power.

What you need is a USB hub with an AC adapter that powers the hub and any devices that are connected to it from the external AC power adapter and NOT from the USB bus. In other words look for an external power adapter that plugs into the wall as well as into the USB port. Don't get a recharger for an iPOD as that will not do you any good. And don't get a hub that says "powered" or "external power" that does not have an AC power adapter because it is still sucking power off of the USB port.

Try shopping for a D-Link DUB-H4 High Speed USB 2.0 4-Port Hub. It is a good choice if you are not going to plug any USB 1.1 devices into it. Read the reviews for any device you choose.
