You could just unplug the hub and plug your mouse into that USB port...

<Ctrl>-<Esc> will get you to the search bar
"Control" will get you to control panel
<Arrow> keys will get you around screen, <Enter> to select something
Control; Administrative Tools; Computer Management; Device Manager

<Tab> will get you to the device tree, go down to USB controllers, find the device and <Del>

Dropping a laptop is never good news. Have you tried to Cold-Start the laptop, unplug. remove battery, leave battery out for now, plug in try to start normally. If that fails, Did you remove the HDD and reseat? The damage from the drops may have jarred something loose. Do you get activity, light blinking, from the HDD? The DVD/CD?

We all have to start somewhere! The simplest way is to see where your mouse is currently plug-in your computer: look for an identical 'USB' socket to the one the mouse is plug-in and plug the USB hub cable plug to this socket. You could also just unplug your mouse from the computer socket and plug the USB hub cable instead AND THEN plug the mouse in one of the socket on your Hub. The computer should automatically install the software require to drive your newly installed USB hub. Hope it helps!

do one thing boot ur vista without usb hub then go to device manager remove your usb drivers of the hub disconnect the hub from computer, restart notebook, then connect the hub back when windows boot let vista to install the driver of that hub, after that connect your devices one by one ok let me know what happen? :-)

Before, you return it, can you unplug the Wireless USB Hub, and plug in your iPod and does it work just fine?  Also, the USB port that you're plugging it into - is it USB 2.0?
If both answers are YES to the above - then definitely return it.
It's not your speakers.

How Old is your computer (depending on age, it may not have USB 2.0) that is what you may need to have a external HD now a days

or is it the drivers?

try to change a new USB cord, and if it does not work the problem is a device then

There was problem at one time with IOGear KVMs not working correctly with the USB chipset on the Dell motherboards. This problem was resolved by using a USB hub between the KVM cable and the computer. The user could take the USB portion of the KVM cable and plug it into a USB hub and then take the USB hub and plug it into the Dell computer. That should help with the problem.

a simple solution is buy a powered usb hub ( which has an adapter which plugs into the mains) that should solve your problem
