Go to my computer>properties>hardware tab>device manager and go down the list to universal serial bus controllers, click on the '+' sign and see if any on the list have a red cross or yellow exclamation mark next to them, if there is '!' then right click and click update driver, if a 'X' then right click and select enable. If still not working, right click anduninstall all the controllers and then restart notebook and the controllers will be re installed and hopefully should solve the problem, if not then there may be a usb port fault on the motherboard

After reading the description, I think you need to try updating BIOS and latest device drivers for USB. Because USB are getting power on that means there would not be any fault to from the motherboard.

So please try updating latest BIOS for your notebook.
If you can provide me the product no for your notebook and the operating system which you are using currently then I can find the one for you.

Otherwise you can also do the same.

Type in the product no. on www.hp.com. Then go to software and driver download page, select the proper OS and search in BIOS ROM pack available for your notebook.

I hope this will help.

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.

The USB ports on my Toshiba A135 S2356 laptop are not working. I tried to use my printer and it says not connected. I bought a new cord but it still doesn't work. What should I do?


1. first check ur USB port using any other USB device, like pen drive, mouse, keyboard,etc.
if system detects that device, then ur USB port is OK!

2. if USB is OK, then the problem is with the 'Printer Driver' not the cord!

3. reinstall the printer driver!

4. update the driver!

5. if USB port is not working, then replace it!

if this helps, tell me.......

First thing you need to do is to know that the USB ports of your laptop is really working. Insert another usb devices or storage such a flash disk. If the flash disk being inserted is not recognized by the system then the usb port you had inserted is malfunctioning or it is defective. But if the other usb devices like the flash disk is working then your new bought mouse is defective. Try to plug the usb mouse to the other ports available in your laptop.

Computer will not find flash drive


Does the flash-drive work on *ANY* computer?
If not, the problem is the flash-drive.

Does your computer have more than one USB port?
Does it work in *ANY* port?

Does a *DIFFERENT* USB-device (mouse, keyboard, printer) work in the USB-port that you are trying to use? If not, the USB port has a problem (either software or hardware).

Usb device not recognize


You mentioned that you uninstalled the unknown device from the Device manager. If you uninstall it then connected your usb flash drive you will see an error again on your device manager. This means that the driver for your usb port is not properly installed.

To install it, visit dell website, look for the model of your machine and locate the driver, download it then install from your machine.

Chances are you reconnected the printer to a different USB port and your default is still set up for the other port...

Look at your printer settings and chances are it set up the printer again for the new port.

Either change your default printer or move the cable back to the original port.
