• P 8470 & HP HP 8440 P: upgrading to W10 Pro 64 bit / device Reporting - unknown device manager

  I have recently upgraded to Windows Pro 64-bit 10.  Machines involved are - 8440p & 8470p running W7 Pro 64-bit.

  The Device Manager shows an unknown device - ACPI\HPQ6000\3 & 33FD14CA & 0.

  Could someone tell me what this is in reference to.  Perhaps point to a driver that I could update.

  Thank you / / Jeff

  You are the very welcome.

  The reason why you don't see the driver is because most of the drivers are missing in support pages, which have not worked directly for HP split into 2 companies from 1 August.

  This is certainly the driver you need.  If the version of W7 works, I can't say.

  See if it works.

  FTP://ftp.HP.com/pub/SoftPaq/sp59001-59500/sp59282.exe

  If this driver does the same thing...

  Go to Device Manager and click on the unknown device of 6000 who need pilots.

  Click on the driver tab, click on set to update driver.  Select her browse my computer for driver software option, then at the bottom of this window, let pick me from a list of drivers for devices on my computer.

  Click on disk and go to C:\SWSetup\sp59282\accelerometer and select the HP Mobile Data Protection sensor and see if the pilot goes like this.

  Here's a partial copy and paste of the accelerometer installation information file.

  As you can see the device is supported by the driver.

  But it's the most recent driver is there, I know.

  [Manufacturer]
  Mfg % = HP, ntamd64

  [HP.ntamd64]
  DeviceDesc % = HPAccelerometerDriverInstall.ntamd64, ACPI\HPQ6000

• Error code 43 in Device Manager.

  I have a 43 error that keeps appearing and disappearing.  USB devices worked for a day then stopped working since.  It started sometime in March, and now they are not coming back.  The USB mouse lights up as if it was on and lights up when you move like its supposed to do but it still does not work.  The keyboard does nothing.  I am currently using a ps/2 keyboard.  I have a Windows 8 Inspiron 660 computer with a motherboard Asrock z77 pro4 and a gtx 275 graphics card.  Although my windows is not 'true' so to speak I bought it on its Web site.  I have also 2 monitors connected, one to the motherboard the other to the graphics card.  In Device Manager, the "unknown devices" are sometimes there and sometimes not.  So far, I have tried

  1. Uninstall the usb ports controllers.
  2. Download the latest drivers for my device.
  3. Update the computer several times.
  4. Unplug the unit and plug the usb devices.
  5. Plug my camera on other computers and they worked,
  6. Connect the other devices work in my computer that did not work.
  7. Thanks to the Fixit kit which does not work.

  I was wondering if I pay for support and it does not solve my problem I would get a refund or not.  I have also to documents on when usb devices worked.

  When the Board of Directors and the mouse worked it showed in Device Manager but the "unknown devices" is a not disappear, even if the keyboard and mouse were the only things connected.

  -Also-

  I just noticed that my "Standard Enhanced PCI to USB Host Controller" has an error of 45 and he said: it's not connect.  I don't know what this means, but it may be useful.

  

  

  

  

  

  -----------------------------------------------Other Information----------------------------------------------------

  It is an error 45 and he says its not connected, it seems important.

  I suggest you try the following steps and check if it helps.

  Remove all USB devices connected to the computer.

  b. press Windows + R keys, type regedit into the run window and press ENTER.

  If you are prompted for an administrator password or a confirmation, type the password, or click on continue.

  (c) in the navigation pane, search for, and then click the following registry subkey:

  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\ {4D36E967-E325-11CE-BFC1-08002BE10318}

  d. in the pane of details, right click 'LowerFilters' and then click 'remove '.

  e. click 'Yes' when prompted.

  f. close the registry editor and restart the computer.

  Note: Serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it.

• External hard drive in the Device Manager but not in disk management

  So I have this external hard drive Western Digital 1 TB. I've had for over a year now and it was working fine. I would like to trade my XBox 360 and the computerregularly. Then one day I brought home, plugged into the computer and nothing. My friend and I couldn't understand anything. We have gone as far as removing the hard drive and put it directly into the computer. I have reviewed, that he has lost.

  Then yesterday, on a whim, I tried to connect it again to the USB port. It is presented in the Device Manager but says that its drivers have not been installed. Then, I changed the USB ports on the back of the computer and as if by magic, that this is once again. I had full access. Stupid (and you can see where this is going) did not immediately transfer anything off the hard drive. I'm looking for an image and listen to a song off of said hard drive when the drive went suddenly not recognized.

  I can see now the reader in the Manager of devices under disk drives, and USB devices. However it does not appear in the disk management window. And Yes, I checked as well the Productdocumentation upper and lower, that it is not listed. Go to the area where you assign drive letters not shown not be. Normally this is E:.

  I also tried to remove the UpperFilters registry in regedit. It was not to remove LowerFilters. Obviously, that didn't work or the other.

  I tried several cords and all my USB ports with no luck either.

  I went on the WD Web site, but they do not offer anything other than a partitioner that I would save rather than as a last resort as there are a number of things on the hard drive I want to save.

  So it's not like it's a new HD to be partitioned or an old man who comes out crapped. I know there's the data I just need to get home long enough to get what I need. Maybe I missed my window, but maybe I did not. Maybe someone can help. I'm at the end of my mind on this thing.

  Sounds like a problem of partition (maybe corrupted partition tables) if the device is recognized, but not the 'disk '.

  There are recovery/repair partition about tools.  Western Digital actually have some but I think that they are made for internal drives.

  If I were you, I start with WD and start looking for partition recovery/repair tools.  If this is the problem then it is the right kind of problem and you using the right type of solution can fix it easily.

  If this is not the case, some data recovery tools can help you recover some files even if you have to recreate a new partition, although I wish you much luck with this approach!

  Good luck whatever you try and make sure that you do not overwrite the what partition information, you have without making backups (many partition edititing software will offer backups)

• Device Manager, Code 19?

  I know that the issue is my computer because when I plug my USB or my mp3 player to my sisters laptop computer, it works fine.

  Two are Standard Enhanced PCI to USB Host Controller and the other four are Standard OpenHCD USB Host Controller. They don't properly uninstall and reinstall and when I try to update it says that they are already updated.

  What should I do? I have Windows Vista and an HP dv7 1464nr. Oh and would be my their also my battery, because my laptop needs a new and can works when it is on the charger now and I noticed the problem around my laptop start cut himself when it was not the prosecution if she told me I have 20% of battery life left.

• Hard drive shows up in Device Manager, but not in 'my computer '.

  I have a Samsung HD103UI SATA hard drive in a dual docking station Thermaltake Black Widow hard drive. I connected it to my laptop via a USB port. It appears in Device Manager and says it's working properly. It however does not appear in my computer. I go to disk management and presents itself, he says "Dynamic Disk 1, invalid. If I right click on the drive, it asks if I want to convert it to base, but if I do that I will lose my data. I hooked this same configuration of my XP machine and it worked fine, no problem. How can I fix without basic conversion and how do I get it to appear in my computer?

  End to this problem, that I had the hard drive on the xp machine unload everything out of it and reformat the hard drive on my Vista laptop. I did once it worked fine and I can move it back from my xp and vista machine. It's the only way I could get this drive to work.
