My son tried to put a usb lead into my pc the wrong way and he bent all copper pins inside is it easy and cheap to repair or could i connect the tower to my laptop???? theres a hard one for you teckno


No, it isn't hard.

Wrapping your mind around Quantum Mechanics, and String Line theory, is a little tough; though. lol!

Will make sense in a moment.

The front of your computer is the Front Panel.
Those are Front Panel USB ports.

On the motherboard are USB headers.
Small rectangular shaped pieces of plastic, that have contact pins sticking up.

EACH USB header will support TWO USB ports in the Front Panel.

Therefore; there will be two cables coming from two USB ports, in the Front Panel; and connect to ONE USB header on the motherboard.

IF, you feel the contact pins in the USB ports in the Front Panel, may be Touching each other; I strongly advise disconnecting the cables TO them.

Disconnect from motherboard.

Why?
Because if they touch each other, it will short the USB header out; on the motherboard.
This = No.

Then just use the USB ports on the back of the computer.

!O_O!

This is to save money, Mark; and save your computer.

Going further; If there are enough funds available, then I suggest replacing the Front Panel I/O/USB/Audio Control Panel Board,

B) Removing and Installing Parts


Connect desktop to laptop to do what?
For USB port availability? IMHO that is like shooting yourself in the foot.

Also, how do you propose to accomplish this?

The USB ports in the Front Panel, are for ease of accessibility.
(As the young tyke has found, lol!)

Connecting a laptop greatly detracts from this.
Jus sayin'.

For additional questions please post in a Comment.

All the usb ports have stopped working, so my printer/scanner and mobile phone downloads are not accessable, nor is my external hard drive that i back up everything on. Front and back of machine!


You may want to check the BIOS settings; reboot and repeatedly press F2 until the setup screen appears. Check the onboard devices section and make sure that the onboard USB ports are enabled, then press F10, select 'Save and exit'. The system will reboot; check the ports again

USB ports not working, slow computer


The error you are getting is the USB port driver. I suggest disconnecting ALL of the items you have connected to ALL of the USB ports and rebooting. If the computer reboots normally, go back and install ONE and ONLY one USB device. Restart your machine. If it boots OK, shut down, remove that device and connect another one, restart again. Do this for EACH of the USB devices until you find one that causes the computer to boot slowly and/or generates the error message. That one is the culprit and needs to be repaired before reattaching to your system.

If, however, after removing all of the USB devices initially and rebooting, you still get the error message, then you have a USB driver problem. You will need to remove the USB driver and reinstall from a known good location (like HP's website) to fix the driver problem.

Usb not found aspire t160


Hi,

i,d check the bios setup. to ensure that USB devices are enabled.
Or that there are no conflicting devices:- My Computer/Control Panel/System/Device Manager.
Also some motherboards, have jumpers to set the USB ports on/off.
Try using a different port if you have 1 available, or purchase an individual PCI-Card with USB Ports On.

Power surge on hub port


Try this to find out which one of your components has an issue. Turn off your machine then unplug all of your USB cables. Turn your machine back on and plug in one of your USB cables. Verify the component you just plugged in works correctly and if it does plug in another cable and verify that component is working. Continue these steps until you have the one component that displays the error you have seen. That component is most likely the cause of your issue and should be replaced.

Good luck, Greased.
