Re: usb to serial controller

Try removing (uninstalling) the driver in the Device Manager. Then download the chipset drivers and run the install. It should identify the correct driver automatically.

When I Connect My Aiptek 8100 camera to the PC, they show a message "USB device not recognized." Is this because I did not install it's driver? If so please tell me where I can find the driver?

Usually usb device not recognized is due to damaged usb cable or usb port..use a different usb cable and connect it to your pc, if your usb cable is ok then connect it to a different usb port. if the problem in not with the usb cable or port install driver from the cd you got with camera. if you dont have that cd download driver from the device manufacturer site.

USB ports wont recognize anything I plug in

Are you using XP? If so:
Here is what you can do to refresh the USB ports:
1. Right click MY COMPUTER
3. Select HARDWARE
6. Right click on each USB CONTROLLER and select Uninstall
7. Uninstall all entries
8. Reboot your computer
9. As your computer re-boots it will reinstall all USB connections it detects
THEN, when all other USB items have been configured and connected by the system, you then should try connecting your USB device.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

Hi, first you need to check window device manager.
On your desktop, Right Click My Computer icon,
select Manage option, and select Device Manager. Look on the list can you see any strange symbol like exclamation when you click on the plus sign next to Universal Serial Bus Controllers. If so, you need to update the Chipset driver on your computer.
Hope this help.

First of all, I recommend you to Uninstall the USB Devices from the Device Manager and reinstall the Chipset Drivers as per the instructions below :
Click on Start and then on Run.
Type devmgmt.msc in the Run Command box and click on OK.
This will open the Device Manager window.
In this, click on the + mark next to Universal Serial Bus Controllers which will display additional USB Entries.
Right click on each of the entry and select Uninstall.
Click on OK if you get any confirmation window. Repeate the same process untill there are no entries left under Universal Serial Bus Controllers in the Device Manager window.
We are done with uninstalling the USB Drivers from the Notebook.

Now, restart the Notebook and close any window which says 'Found new hardware'

Now, download and install the Chipset Driver in your Notebook from the link below :

Save the file in the Notebook and double click to install the Chipset Drivers.
However, if the issue with the USB Ports persists, I recommend you to check again with different devices to confirm if the issue is with the USB Ports of the Notebook itself.
If the Notebook doesnot recognize any of the USB Devices after installing the Chipset Drivers, you may need to get the USB Ports of the Notebook replaced or go with a PCMCIA USB Card.
Hope this helps....

Acer Aspire 5050-5430 USB ports stopped working

I hope i can help resolve your problem for you.
this may be a problem relating to your system device driver files.
Try This:-
go to My Computer/Control Panel/System/Hardware/Device Manager. at the bottom of the page you will see USB.
If you have any yellow symbols ( exclamation Marks ) then the driver has been corrupted, or installed incorrectly.
if you have a system restore disk. this may solve the problem for you. or recovery cd.
If you require further assistance, please ask.

Keyboard is not getting recognized on acer 5051

Dear npjay,

Please connect a usb keyboard at one of the laptop's port. This will most likely (and hopefully) trigger windows installation to use this one.
