Re: have exteranal usb card -

Sounds like the daughter card may be partially disconnected from the main motherboard. The usb ports on this model are on a seprate daughter card, and connect using a small socket to the bottom of the main motherboard. If you can pull it all apart you will be able to easily re-seat this card. Another option is the daughter card is going bad, or the usb ports and or drivers are bad, but it sounds like the card is not properly seated.

It worked before but then said it cant be detected at all

What cant be detected? That error usually means that either a peripheral device (such as a printer, camera or MP3 player) or an internal board (such as a modem, network card, or keyboard or touch pad) is not being recognized by the machine. Generally the error will say what it cant detect, something like "Network not detected" or "Unable to detect video board"

You have not supplied us with vital information to assist you. To give you the specific fix we would need Make & Model of your laptop, what operating system you have loaded (which version of Windows or is it one of the Linux systems) but I will try to help you narrow it down.

First disconnect all wires from the laptop except the power cord. Now turn on the power switch. If you get an error, come back and tell us exactly what it says.

Then start plugging in your peripheral devices (printer, USBs, network, camera, MP3) ONE device at a time. Each time you plug one device give it a minute or two to see it that new device is detected. Lets say that you plug a device and it does not get detected properly, you probably should start by reloading the software drivers for that device.

Start with this and write us back and well give you the next steps.

Yesterday I had put connected the USB charger port to my ipod to charge it. When I did this I seen it said"HUB exceeded limit" or something like that. I also noticed that the internet was off as...

Did you try disconnecting all USB connections from the laptop?
The "HUB exceeded limit" error message is telling you that you have too many things using too much power on your USB connections.

Please disconnect all USB connection, disconnect the power cord, and remove the laptop battery. Next press and hold the power button down for 30 seconds to drain away any residual electrical charge from your system
Install the battery and plug in the power cord again -- do NOT plug in any USB connections at this time.

Try to boot the laptop as normal. If the laptop does not boot as normal now, then you will need to take the laptop in for service.
If it does boot normally, only plug-in the USB adapters that you currently need -- one or two at a time in order to prevent future overloads.

If you absolutely need all of the USB devices plugged-in at the same time, then I suggest that you buy an powered USB HUB to plug all devices in to.

Having transcend 4 GB pend drive but when i insert into my laptop the drive did not open

When a pen drive isn't recognized it is either the pen drive or the usb port. First thing is to try it in the other ports. You can try rebooting the computer with the drive not connected and see if it finds it. Next try it on a different computer. If it finds it then the problem is on the usb port on the first computer.

If it is not recognized on any computer then the pen drive has failed and it is unlikly that you can do anything but replace it with a new one. If it is recognized but not being read on any computer you may be able to use the systems error checking tools to correct the problem and use the drive again. You can also format it and get it working but you loose your stored information.

To use error checking:
Detecting and repairing disk errors
  1. Open shortcutcold.gifMy Computer, and then select the local disk you want to check.
  2. On the File menu, click Properties.
  3. On the Tools tab, under Error-checking, click Check Now.
  4. Under Check disk options, select the Scan for and attempt recovery of bad sectors check box.
note.gif Notes
  • To open My Computer, click Start, and then click My Computer.
  • All files must be closed for this process to run. If the volume is currently in use, a message box will appear prompting you to indicate whether or not you want to reschedule the disk checking for the next time you restart your system. Then, the next time you restart your system, disk checking will run. Your volume will not be available to perform other tasks while this process is running.

To format it: use the same instructions and instead choose the format option.

If none of that makes it behave all you can do is replace it.

Don't stay on

You might have a bad optical drive. One way to test this is to get an external usb drive, enter setup (bios) upon start up, and change the first boot device to usb device\exteranal drive, then use the exteranal drive. If it works, then you know you have a bad drive.

Acer webcam USB probelm

Is the webcam USB? Try rebooting the computer with no other USB devices connected. If you're still having the problem try it through a separate mains powered hub. Webcams can often overload the USB ports on laptops.

USB DEvice not recognized

My apologies faizakhatib. I see that you did, indeed, provide the make and model of you laptop. Thank you for that.

Some additional suggestions:
(A) Please, make sure that your laptop's A/C adapter is plugged in while trouble-shooting this issue. We don't want to complicate the matter w/ a possible low-power issue.

(B) Worse case, your laptop's USB interface may have failed (hardware failure). To repair this would necessitate replacing your motherboard. You can work around this issue, however, by using a laptop PC card w/ USB ports.

Please, get back to us w/ your answers and we'll work w/ you to diagnose this issue.

Thank you,

The Mp3 player may need a powered USB2 supply and not a peripheral powered supply. The only reason your other usb ports may not work is that the controllers need re-installing or they are not enabled; see this post:-
