The USB interface is rugged and is designed to only allow a connector insertion one way. However, if a connector is upside-down and forcefully jammed into the port at an angle, it is possible shove it in and in doing so breaking the port's hardware. If you examine the port closely, you may see the part with four contacts bent such that the contacts are shorting to the metal shell of the port. Inserting a small piece of cardboard between the contacts and the shell may be sufficient to remove the short and so allow start up to proceed past the power up check of the USB ports. If this doesn't work, you can try pressing F8 repeatedly on power up to get into Windows safe mode menu where you can select different modes of start up including one without any drivers which may allow you to bypass the USB hardware problem. But this is a makeshift solution which only gives you very limited functionality. If the laptop is still under warranty, take it in for repair by a qualified technician. If the cardboard trick works and you don't care if one USB port is no longer functionable, then you can as an alternative just leave things as they are.

Follow the steps given below to refresh USB ports.

1. Right-click My Computer icon on the desktop, and then select Properties.
2. Click the Hardware tab.
3. Click the Device Manager button.
4. Click the plus (+) sign to the left of Universal Serial Bus controllers.
5. Right-click the device listed under Universal Serial Bus controller and select Uninstall.
6. Click OK to confirm the removal of the device.

Please note, repeat Steps 5 and 6 until all the devices under Universal Serial Bus Controller are removed.

7. Shut down the computer.

CAUTION: Ensure that the Shut Down option is selected, instead of the Restart option.

My two usb ports have moved towards inside of computer . i tried to disemble the computer without sucess. all srews battery, harddrive have been taken out. what else must i do to remove back cover


This issue requires intricate soldering, you need to send it to Toshiba for motherboard replacement. Most likely, the USB ports were pushed in too hard and the port broke off of its location. Even if you were able to access them, it is unlikely you could fix. However, this model is still fairly new, so send it to them and claim it came that way...

HP3600 USB printer works but won't print on my HP7058 Laptop


Try removing all ports from your laptop, then reboot, and then create just one USB port. Also, go to your hardware devices and make sure your usb ports don't have any question marks or yellow warning symbols. Be sure first that the drivers for your USB ports are installed and working first. This sounds either a faulty USB cord, which does happen, or USB drivers issues in your laptop. The printer is probably not the problem here.

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.......

Canon mp620 not connecting to my wifi laptop


This could happen if the port that you are using is not the right one.

When you are using a printer wireless, you need to use the Standard TCP/IP port, to setup a printer port, do the following

Right click on printer icon, select properties
Click on Add port, select new port
Enter the IP address of the printer, this can be obtained by printing the settings page from the printer.

Note: please setup a static IP for your printer, else everytime you restart you may endup with a new IP

Let me know if this works,

My computer recognises the printer is there, but nothing prints


With the Lexmark printers communication subsystem you MUST let the driver ask for you to plug in the printer. DO NOT plug the printer into the USB port until told to do so.

To fix a fouled install :
(1) Uninstall the Lexmark drivers in Add Remove Programs
(2) Shutdown the computer
(3) Disconnect the printer from the USB port
(4) Restart the computer
(5) Run the Driver Installation software
(6) Cancel ALL attempts by windows to auto install the printer
(7) When the sofware asks for the printer connect it and continue

Resetting your USB Controllers I'm going to assume that you're running XP (home or pro). Recently I had to refresh my USB ports. This is the sequence I used.
1. Right-click My Computer and select Properties
2. Click Hardware
3. Click Device Manager
4. Expand the Universal Serial Bus Controller
5. Right-click each USB device listed and select Uninstall
6. Click OK to confirm removal of each device

Note: Repeat steps 5 and 6 until all devices under UBS Controller are removed

7. Shut down computer.
CAUTION: Ensure that the Shut Down option is selected instead of Restart.
8. Wait a few seconds and turn computer on. When it reboots you will see "Windows has detected new or added hardware"

Note: You will have to insert your Windows CD, if prompted.

These steps will refresh the USB ports.

Added Notes: 1) If your mouse is a USB you will have to use the keyboard to shut down your computer. 2) It would be wise to unplug everything from your USB ports EXCEPT your mouse and/or keyboard before you restart the computer to avoid Windows replicating any printers, scanners, digi-cams, etc. Once Windows has refreshed your USB controllers and ports, shut down again. reconnect, and restart.

Good Luck

USB port problems with hp printer


There are few things to remember using USB.
  • If your System is in hybernation mode, don't remove any attached USB device, because it will damage your USB driver. This is one of the known problem from microsoft.
  • If you have to remove any USB device use 'Safely Remove Hardware'.

To remove currepted USB drivers its not enough to remove your printer drivers.
  1. You should un-install the 'Universal Serial Bus Controllers' from Device Manager.
  2. Then re-boot to clean registry.
  3. Install the 'Universal Serial Bus Controllers' using XP Setup CD.
  4. Then check the Mass storage, PDA etc, it should recognized by XP.
  5. Then install printer driver (don't attach printer to system untill setup finish or setup says to connect).

I think it will fix.
Please let me know your feed-back.

Thanks

Laptop doesn't recognize my printer


unusual not to be recognised, assuming you have followed the instructions word for word, eg not connected the printer until told to etc, you may have a problem with the usb port and not the printer, so to illiminate this try installing in a different usb port. Also try this driver from the Samsung web site http://www.samsung.com/Products/PrinterandMultifunction/BlackWhiteLaserPrintersforHomeandHomeOffice/ML_2010XAA.asp If still no luck then it's either the printer or a usb port problem, to illiminate the usb fault, go to my computer, right click>properties>hardware tab>device manager> and go down the bottom of the list to usb controllers, click on '+' sign, right click and select uninstall. Restart pc and all the usb controllers will be re installed automatically. Try the printer again, if still not installing the fault must be the printer.
