Usb port not working - Toshiba Satellite L675D-S7016 Laptop

Hi,
Which USB port Damage because there are two USB port available.
One is Printer USB port or Sec is PC USB port.
If you are say PC USB port not working first you check it USB driver installed or not, or USB connect to motherboard or not. PC there are two side USB available one is front side and sec is back side. You connect only back side, because this USB connect to main board. So you connect only back side. If not working removed driver or installed driver.
Or if you are say printer USB then change cable or port or not solved only change option.

try to update or download the usb cord of your laptop

Printers are particular about which usb port they are plugged into, a virtual printer port is assigned to USB1 in the computer, when you select the printer port for it to use. You may need to plug the printer into each USB port, until you fine the USB port 1 which it works in, remember to always connect it to this same usb port, otherwise it will not work. There is only one USB port number 1.

First determine that the USB port isn't dead. Do other things work in that USB port? If the answer is yes we know it's not the port. Have you tried another USP port? If it doesn't work in another port (or on another computer's USB port) then it's the adapter itself.

Adapters can go bad. USB ports usually work and don't go out. The exception is that many laptops that come with several USB ports sometimes have one (or more) that never did work.

Try it on another computer. This is one last step to determine if the adapter itself is dead and that it isn't something on/with your computer.

It also could be that the computer has the old USB 1 port and the adapter needs USB 2. (USB 1 was slower).

Hi,
Did you install any Anti virus . Check the USB port for any physical damage. Try connecting a mouse with USB port to check if its working. After all this then the issue remain the same then the USB port needs an replacement.

Are you using an external power supply for the disk? If not, you might be overloading the USB port. It should not happen, but USB ports are limited in the amount of power they can output. Especially laptops might face such problems.

Do other USB devices still work on those USB ports? If so then the port is at least not broken.
Sometimes you can uninstall and reinstall the USB hubs and controller devices in the Device Manager to fix USB problems.

It sound like your USB Ports is the problem. Go to the Hardware manager delete the USB Ports and then shutdown and power back up.
The system then should reinstall the USB Ports and associated drivers. If not the USB Ports were probably fried by the power outage.

Your computer is functioning correctly.
The USB ports on your laptop are USB1 ports its pard of the hardware.
Your PCMCIA USB 2 card runs at USB 2 speed and therefore when you connect a USB 2 device to this port you will not get this USB message.

use 2.0 ports and not less than that.if still nothing works out,check your port connections or that of ur printer.

As you stated the device works in one slot but not the other , tells you there is problem with that usb port , don't use those ports , best thing to do is purchase a PCI USB card if you need more USB ports .
