ERROR CODE 43 General Solutions

ERROR CODE 43: Microsoft describe that this error happen because "One of the drivers controlling the device notified the operating system that the device failed in some manner. "
There are several way to solve this problem, and from my opinion this happen basically cause by the SOFTWARE or the HARDWARE. There is no specific reason why this happen, a mystery that cause us a headache to figure what cause this error.

THE CAUSE:

Theoretically, from the solution we may guess what the causes, such as dusty hardware, electrical overcharge on the component, faulty hardware or corrupted Windows file. This may happen on both the external or Internal hardware which is based on USB type hardware, such as Pendrive (USB storage), Card reader, USB Mouse and Keyboard, Webcam etc and it can happen on all windows operating system.

IMPORTANT!
-this post  for those who getting the ERROR CODE 43 Only!.

SOLUTION:

This solution is a compilation from my reading and experience, if you have a another solution, share it here, it will help others too.

1. CHECK THE DEVICE AND USB PORT.

- try to plug the USB in your friend computer, if does't work, try on another friend computer, if still doesn't work, get a new one.
- If there are drivers released by your manufacture for the device, download and reinstall it.
- Make sure you also try on other USB port available on your PC.

this step is to make sure the hardware is not faulty.

2. RESET.

a) Reset the CMOS - (please make sure you know how to open your laptop or assisted by the manual or experienced friend) , take out the CMOS for 15 minutes (unplug power chord and battery) and put it back.

b) Power Reset - base on Darwin's step brother theory that they might be electrical overcharge on the Computer component including the USB port. Unplug the battery and Power chord. make sure there are no any electrical source connected with your computer. wait for 15 minute to plug it back and turn on your pc.

3. RESTORE

If yesterday or last week the USB port/Device work like charm, and today it does not work anymore. Perform system restore. If you need a guide on that, refer to my tutorial here.

4. CLEAN YOUR PC.

Take out the RAM, HDD, WIFI CARD and CMOS. Clean it with DRY brush or blow some air to remove the dust. Make sure you also clean the USB port and Keyboard with the brush.


The solution above is the basic solution, below is the solution which i prefer the last step to take.

5. UNISTALL and REINSTALL THE DRIVER

open device manager, right click on the device with yellow and select unistall, the restart and update the driver (automatically)

6. BIOS

It kinda weird because there are users who manage to solve this by updating the BIOS. Download the latest BIOS from your manufacture site. Flash and turn on the PC. NOTE: FLASHING WRONG BIOS CAN DAMAGE YOUR PC, SO I STRONGLY RECOMMEND FOR NEW USER TO SKIP THIS METHOD.

7. REINSTALL OS

Well, this method maybe kinda lame but this is my favorite method  which is reinstall windows with or without formatting.


SOME NOTES:

1. WINDOWS UPDATE : I don't know weather windows update can cause this, but if it happen after windows update,  just uninstall it from the control panel (start - control panel - uninstall program/add remove program). On the other hand, you can also search fixes from Microsoft by run automatic updates, select custom and search for human interface devices. Install it.

2. VIRUS: there are no reports which this error cause by the virus/spam etc. Unless the virus already conquered your OS for centuries, then no need think for the solution, just format and reinstall windows.


3. MICROSOT FIX: Still no details from microsoft, they just tell you to refer to the manufacture documentation.


Your feedback and suggestion are most welcome.

Unknown Device Solutions

INTRODUCTION:
Base on my experience troubleshooting computers, sometimes the computer system (windows) unable to detect the hardware changes whenever we plug in storage (like thumb drive, memory card, etc). Or after installing all drivers there are still driver missing which listed as "unknown device" in device manager.
So here i would like to share my experience how to solve this problem because there are many reason why your computers get the unknown device problem.

IF you have the error and prompt with " Disk management console view is not up to date" whenever you insert memory card or usb drive you can refer my tutorial here:
http://laptop-driver.blogspot.com/2010/12/disk-management-console-view-is-not-up.html


CONTENT:

1. Unknown device - in device manager
Devices that detected as unknown device after installing windows.

2. Unknown device - USB storage and New Hardware
Unknown device appear after inserting USB storage such as thumdrive into the USB slot or other computer port.

Note: to open device manager click START and on the serach box type DEVMGMT.MSC and press ENTER. In windows 8 right click on lower left corner at the power user start button and select device manager.

1 - UNKNOWN DEVICE - IN DEVICE MANAGER
You will see picture like this.



 NOTE:
The solution is step by step process, which is say A didn't work, so move to solution B.
If you didn't find unknown device and there's no hardware detected after insert the USB device into the USB slot, click VIEW in device manager and select SHOW HIDDEN DEVICE.

1A: INSTALL AND UNISTALL
1. Right click on the unknown device. Select uninstall. It will disappear from the list.
2. Right lcik again on any device there and select scan for hardware changes.
3. A new hardware found displayed and select automatically install driver.

1B: IDENTIFYING THE UNKNOWN DEVICE AND GET THE APPROPRIATE DRIVER.
1. To identify what is the unknown device, first we must get the hardware ID.
2. To get the hardware ID you can read my tutorial here:
     http://laptop-driver.blogspot.com/2009/12/how-to-check-hardware-id.html
3. After you get the hardware ID refer to the list below:

ACPI\HPQ0006
ACPI\HPQ0007
HP Quicklaunch Button : Download link -  SP45058

ACPI/HPQ0004
HP Hard Driver Smart Protection Download link - SP45501

ACPI\ENE0100
ENE CIR Reciever (Infrared) Download link - sp45308

ACPI\AWY0001\2&DABA3FF&0
Away Mode Driver Download link - http://www.nvidia.com/object/nforce_winxp_15.26.html
or: http://data.versiontracker.com/drivers/manual/msi/AMDAway_MB.zip

ACPI\VEN_HPQ&DEV_6001
HP Wireless Button Driver : Download link : sp58720 
If you cannot enable f12 function use this driver: sp59199



ACPI\IFX0102
Ifineon trusted module: Download link 

USB\VID_138A&PID_003D&REV_0104
Validity Fingerprint sensor driver : Download link

My hardware ID is not listed here, what to do?
-post your hardware ID here and i will recommend the compatible driver for you.
Another trick: Google the hardware ID and you will get the information about the device and drivers.

2. USB STORAGE AND NEW HARDWARE.

This section will discuss the problem with USB drive such as thumb drive and memory card which detected as unknow device.

SECTION 2A:
1. First thing to do is similar with previous post section 1A.
2. Try to plug the USB into other port.
3. If still didn't work try the USB on other computer, if still detected as unknow means there are problem with the hardware. It may refer to faulty hardware.
4. If it work on other computer and not yours, maybe you are missing USB driver/OS patch/upgrade/fix which you can download from your computer manufacture site.

SECTION 2B:
1. Open drive management by click start and type DRVMGMT.MSC and press ENTER.
2. Look at the drive listed and see if the disk is detected. If not means there are problem your your hardware. Test it with other computer and if detected on other computer you must try with different usb slot on your computer.
3. For memory card make sure you computer can support the size of the card, example some computer only can read up to 2GB memory reader, and unable to detect or read higher than that.
4. Malware and virus maybe one of the cause but it never happen to me and no report from users about this.

EXPERT MODE:

Generally speaking, people who like computers love to try anything to fix and test.

I always have multiple OS in my computers and normally if i have problem with USB detected as unknown i will test it on Ubuntu or other linux distribution such as linux mint. (I always change my linux OS). If you have Mac OS it will not detect storage in FAT and NTFS.
If my linux can read it, i backup the file and reformat the USB. So far there is only 2 result i got, if it detected reformat than when i plug in windows OS no more unknown and the USB work perfectly. If it not detected in LINUX mean it is hardware Faulty.

If you have suggestion to improve this post I'm really happy to hear it.
Comments and feedback are most welcome.
