Re: usb not recognized
Try to load the BIOS defaults. Tap F2 when you turn it on. On the
system setup screen, press F9 to load defaults. F10 to save and exit.it might not work on vista but u can try this
try uninstall and reinstall the USB driver.
Start Menu>Control Panel>Device Manager>Universal Hub
Controller, right click the driver and then click uninstall. then
restart your computer so that it may reinstall your driver.
Toshiba laptops in the past have supplied only about 100ma (rather than
the 500ma usually available) at the USB ports. (That's to make the
battery hold its charge longer.)I definitely can not guarantee that a powered hub will solve the problem. You might make arrangements to borrow one.try and perform allthe steps above and try and reinstall the operating system also if still it doesnt work then definately replace the motherboard or take it to the local technician and tell him to replace the motherboard......hope this will work

First of all, I am assuming you are using a current laptop with USB connectors. For a corded mouse, insert the USB plug into a USB socket. After the computer recognizes the mouse, use the computer control panel software to set up the mouse. For a USB wireless mouse, insert the dongle into a USB socket. After the computer recognizes the dongle, use the computer control panel software to set up the mouse.
I called Dynex customer support and they walked me through the troubleshooting process. It turns out there was a problem or conflict with one of my usb ports. The port recognizes my flash drive and other usb devices but not the mouse. I tried using the other two remaining ports and the mouse was recognized and works just fine.
Make sure you are connecting it to your system through a USB 2.0 Port, and not 1.0 USB Port.
Next, uninstall the Wireless presenter totally from the System first,
Then go to "scan for hardware changes",
This will bring up a prompt to install the new hardware found (Which is your Wireless presenter).
After this, ensure that it is On, then Scan for wireless networks.
It should connect like that.
(In case you don't know how to uninstall the Adapter, Right-Click on my computer Icon, Properties, Device Manager, then select the Adapter under network adapters, and right click on it, then select uninstall.)
Got the easiest solution to the problem. It worked for me, hope it helps all of you too.
First of all, if the device is unrecognizable, go to Device Manager and remove (not disable) the device. After doing so, remove the USB connector from the port.
Next, go to http://www.logitech.com/en-my/support-downloads?wt.mc_id=usym_redirect_/index/downloads, and look for your mouse/keyboard etc model. Choose the one that you own and choose the Software Downloads option. Next, follow the steps and install the Logitech Connection Utility.
Once installed, follow the steps given and hopefully your device should be reconnected once again. Hope it helps all the best!
go to device amanger then uninstall all usb drivers from computer then restart the computrer then it autoinstall all usb drivers. tehn connect your usb mouse cable to computer try all usb port then if problem arise then your mouse usb chip has issue.
Thanks for using fixya. Please rate solution if it helps.
Reinstall your CD software program for your mouse because it was wiped out when you went back to factory settings.
Try disconnecting the Mouse Receiver from the
USB port and reinstall the CD software program. When
the program asks you to connect the MouseReceiver to the USB
port, do so and it should work.
Hope this helps. Bud
Make sure its driver on the mouse is working fine and that windows finds it right click on MY Computer then go to hardware, device manager and right click on Mouse and see if it is installed correctly try reinstalling driver for that mouse.
