Hardware Drivers :: Required Device Isn't Connected Or Can't Be Accessed
Sep 15, 2014
I'm having an issue with a pc I am fixing. I reflowed the gpu and removed some viruses but now every time I restart the pc I get this message which I can fix with the installation media. But every time i fix it, once I turn the computer off again after using it normally for whatever amount of time, when I turn it on again, i get the blue screen again. What's causing it to happen every time?

Windows 8 has been acting up recently, every now and again my computer will blue screen and restart with the message
error-code-0xc000000f-windows-8-a-required-device-isnt-connected-or-cant-be-accessed
So far I have noticed that if you leave the computer off for a while or change the hard drive to a different sata port it will work fine for a while then do the same thing.
Also I have done a full clean install with windows 8 and the same issue has occured a couple of days later.
I have a feeling its the hard drive going bad but how can i be sure? Some hard drive utilities have reported "end to end error - fail" but others have said there is no issues.

I am running Windows 8 on an Asus laptop. Two days ago it was doing updates and restarting. It did this 3 times, and on the third restart I received the blue error screen. It stated
"Recovery. Your pc needs to be repaired. A required device isn't connected or can't be accessed. Error code: 0xc0000225
You'll need to use the recovery tools on your installation media. If you don't have any installation media [like a disc or usb device] contact your system administrator or Pc manufacturer."
It gives me three options at the bottom [press enter to try again, press f8 for startup settings, press esc for uefi firmware settings]. If I press enter I get the same screen just with a bit more text. f8 does nothing. Uefi takes me to the boot menu. I have been trying to boot from a dvd r with a flash operating system in order to recover my data before it is reformatted. However, it does not seem to recognize the disc. When I select to boot from dvd rom, it tries, then on the black screen appears text saying restart and select boot device or install boot media and press a key. I tried taking disc out and putting bavk in, then pressing a key, nothing, same message.

I have a windows 8 laptop and a linux desktop, both connected to the same screen using hdmi - since my screen has only 1 HDMI input, I use an HDMI splitter.
Every time I move from the linux to the windows 8 laptop (using a HDMI mini remote control), I get a message from windows saying that in order to apply these changes I need to reboot.
Note that I also use the same wireless keyboard and mouse for both computers - each time I change from one computer to the other, I unplug the USB that controls them and plug it in the computer I will use.
I think that the problem is related to the HDMI, not the keyboard/mouse usb - but I am not sure.
Needless to say that it is very annoying and I cant keep restarting the LT each time I move from one to the other.
I checked event viewer to see what causes this and these are the relevant messages:
1 - Device 'USBVID_045E&PID_0745&MI_017&1a5cec9a&0&0001' requires installation.
Microsoft-Windows-Kernel-PnPConfig/Configuration
Kernel-PnPConfig
Event id: 3
2 - A reboot is required to complete device installation of device 'USBVID_045E&PID_0745&MI_017&1a5cec9a&0&0001'
Microsoft-Windows-UserPnp/DeviceInstall
UserPnp
Event id: 8000
how I can fix this, make it stop requesting reboots?

When I connect my DualShock 3 controller to my Windows 8.1 laptop it does not charge. I hear a beep, as in something was connected to the PC, then it seems to charge for a couple of seconds (lights flash on the controller) and then it stops. I am able to charge my phone and tablet so, it's just the DS3. It works fine on my Windows 7 computer, so it's not the controller.

I am trying to install the new develp build of Windows 8 (x86) on my asus eeepc 1005pe. This is a netbook which doesnt even have a cd/dvd drive.
So anyway, I extracted the iso on a bootable usb flash drive. I boot, and when I click install it just hangs for about 10 minutes and then it gives me this error:
I tried setting the bios from AHCI to IDE. This does not work, I even get a bluescreen of death when I boot up in the current win7 sp1 install. But anyway on google I read a lot about this problem and one of the solutions is to put it on AHCI.. but not for me as it was already on AHCI. Anyway IDE is not workin either.
Just recently I installed win7sp1 on this netbook without a problem. I checked the sha1 hashes of the Windows 8 ISO and they are confirmed, so that is not the problem either.

When connecting my PC to my TV through HDMI cable sometimes the playback device does not recognise my TV. While the picture on my TV is great I don't get sound. Sometimes it works.
I am not sure if this has to do with the cable ( its a good HDMI cable though) or with the graphics card or with the TV.

Last part of the message, (Device Descriptor Request Failed). I get this, in Device Manager, and I have searched for an answer on the net. Also it is a Code 43. I went through my laptop, with an HP Technician this morning, I might add at a cost of 5p/minute, for 30 odd minutes. He has said that because I had gone over to Windows 8.1 and the recovery discs I made will not load, to put back in Windows 8. I have to send the laptop back for re-installing the OS, because Windows 8.1 do not have the update for my problem. Also the R.H. USB socket has a failure ID:0GAPTK-6T7716-MFPWWK-8D1Q03. I personally think that this is all what the problem is. a duff USB. Is this a cop-out???
Does Windows 8.1 having driver WHQL problems?
I only found out the problem with the usb when I tried to download a Mobi file to a Kindle for my wife. The other usb's work OK.

When I have a powered usb hub connected, my windows 8 will not start. The same usb hub connected to xp or to windows 7 does not cause problems. But it does in windows 8. So I need to disconnect that hub and start windows 8 without it and connect it after windows 8 has booted. Said hub has two drives attached: 1 32GB and a 1 TB. How come Windows 8 cannot handle it?

I am unsure whether I should enable "Automatically get device drivers, apps, and info for new devices" when installing Windows 8 Pro?
What exactly will it do?
If I enable this, will Windows then automatically install software packages/drivers from the manufacturer, like for example the Logitech Setpoint software for their keyboards and mouse and similar software for other devices? I don't want or need that. Or will it behave like in Windows 7?
On my other PC with Windows 7 I see in Windows Update that there are a couple of optional updates, including that Logitech stuff, as well as some driver for a BenQ monitor I have and also nvidia video drivers. This kind of stuff I don't want or need installed automatically as important updates in Windows Update - so I am worried if enabling this automatic driver stuff in Windows 8 is different than Windows 7? Meaning that it will get installed secretly/automatically?
However, it's fine that Windows finds them so I can manually go and check if I want to install any of it.
The key is that the updates are optional in Windows 7, but I have seen a few people complain about Windows 8 installing stuff like video drivers and mouse drivers automatically.

I've installed Microsoft Windows 8.1 Version 6.3.9600 Build 9600 on my HP 430 Notebook PC with 1 GB RAM and Pentium CPU @ 2GHz 2 Cores.
Display drivers are not working properly (i.e., everything appears bigger and unclear), earlier I'd successfully updated the display drivers and made it work using Device Manager. making a backup of the drivers (may be in .inf format) from the installed drivers so that I don't have to update it every time I re-install it.

The issue is finding the file location for my flash drive. My computer only has 3 external USB ports. I have tried all of them, when the flash drive is plugged in somewhere on my computer it should indicate another drive location. I can't find anything....not sure where to look or if I'm looking in the right place. All that shows is c: drive & E: drive. The E: drive is exclusive for the OS system restore (can't be used; not accessible for anything else). The only other is the DVD drive. Nowhere can I find evidence of the flash drive plugged into the USB.
I have all the essential drivers & everything is up to date [I have a task scheduler & Driver updater software installed. All drivers are up to date. This is a new computer, only 2 months old].
I have gone into device manager & checked all the USB & composite serial bus controllers to make sure they are powered on (my computer has an energy saving management thing & it will possibly deactivate the hubs when not in use). According to the power management settings they are not set to "sleep" but all ports are active. I can't figure out why I can't find my drive, nothing is appearing when I have the flash drive plugged in.

I connected a hard drive to my PC. I was able to read/write to it just fine. In fact, I've used it various times in the past. I just tried connecting it again now, and the drive is not showing up on Windows 8.1 at all. It's not being detected.
I connected the drive to a Mac to see if it was the drive, but it wasn't: the Mac was able to read it just fine.
I've had a similar situation in the past with this machine, where my iPhone was, seemingly out of nowhere, no longer recognized by the system. Plugging it in would register on the phone, but the PC wouldn't acknowledge its existence.
I'm completely at a loss as to why this can be. Other drives connect to the PC just fine (in fact, I have another one connected now, as I write this, backing up some data).

I'm running a custom build PC on which I clean installed a (legal) copy of Windows 8.1
My system works fine except it can not install drivers for ANYTHING non-standard. Keyboard, mouse, memory sticks, HDDs all work fine, however when I plug in my phone/tablet/camera etc via USB, it fails to install drivers and I can't use my device.
Here's what device manager looks like with my (android) phone plugged in
And when I select Update driver software, I get this error:

Ever since the feature 'about:tabs' has existed in IE, I have been using it as my home page. 90% of the time, if I open IE, I will want to launch one of the ten most often accessed pages.
Since installing Windows 8.1 and IE11 which came with it, 'about:tabs' is not working consistently, most of the boxes remain empty, and those that previously were filled become empty. What changed?

I upgraded my Windows 7 to Windows 8 pro back in November. Windows explorer has always had issues but now I cant open windows explorer (any way) without it crashing and reload. In SAFE MODE it seems to work fine. I have tried disabling all the Services (non MS) and the Startup function but in normal mode but Windows Explorer still crashes.
I'm definitely not the only one experiencing this issue. A quick search online shows other people reporting their Windows 8 explorer frequently crashes. Is there a solution or something I should try to see if it can resolve the issue?

When I click on a link needing Adobe Flash from within a Metro app, I get a message that I need to install adobe flash. However if I access the same content from within the desktop's IE, it will play.
I have the feeling I'm missing just a switch or something.

I recently bought a cheap USB Hub off eBay. I plugged it in and connected my devices and it always works.
However, about 75% of the time when Win 8 boots, I get about a dozen "USB connect/disconnect" sounds and a window that says "USB Device not recognized". (sometimes 3 or 4 of these windows)
I've searched for this issue but every post that I find provides a recommendation for a USB device that is not working. None of these suggestions applies because after all the boot noise, the hub and it's devices work. It just seems like Win 8 is having trouble recognizing the Hub but keeps trying and eventually succeeds.
The Hub is plugged into a USB 2 port with a scroll wheel mouse and a Dymo LabelWriter 400 connected to the hub.

No USB device seems to be getting detected on my machine when I plug in a flash drive or an external hdd I get the distinctive sound from my speakers that an USB device is plugged in but nothing is showing up in "My Computer". I went through the event logs and found that Windows is failing to load the USB device (check image in attachment logs.jpeg). Recently I installed iTunes, so I though it might be causing this problem but I uninstalled it even then the problem persists. I don't want to format my machine just because of this small problem. Is this a driver conflict ? How do I find out why windows is all of a sudden failing to load the USB devices ? I have uploaded a copy of the saved logs detailing this failure(logs.zip).

I have a Seagate GoFlex 1 Tb USB 3.0 drive. All worked good until a week or two ago. Now the drive will not be recognized when plugged into a USB 3.0 port, the error given is "Unknown USB Device (Device Failed Enumeration).
If I plug the GoFlex drive into a a USB 2.0 port, it works. I can plug USB 2.0 devices into the USB 3.0 port and they work. I just can't plug my USB 3.0 drive into a USB 3.0 port and get it to work.
I have tried uninstalling the Unknown USB Device in Device Manager. I've also uninstalled all other instances of it failing to be recognized.
My motherboard has a VIA VL805 USB controller. I've used the drivers on Gigabyte's site and I've used VIA's drivers, no difference. I have the latest BIOS for my motherboard.
The drive does not show up in Disk Management when plugged into a USB 3.0 port. This shouldn't be a surprise since the device is unknown in the Device Manager.
I thought the problem might be with the USB 3.0 cable or the GoFlex drive's USB interface. So I bought a new USB 3.0 docking station and...same problem. The new docking station also fails enumeration. Basically what it boils down to is a USB 3.0 storage device will not be recognized in a USB 3.0 port. But they work when plugged into a USB 2.0 port.

I have a strange problem: connecting a Canon Powershot G10 digital camera via USB 2.0 to my Win 8.1 laptop presents no problem (info pops up).
But: Using the same cable connected to my desktop PC, there is no reaction whatsoever. No device manager listing, no error message. The USB ports are all working perfectly with other devices (sticks, external hard drive, wireless mouse & keyboard). Moreover, until some weeks ago, the Canon camera was recognized normally.
Short of re-installing the whole USB controller

It's really annoying because the connection is a bit worn, and it keeps connecting and disconnecting...connecting and disconnecting...connecting and disconnecting...connecting and disconnecting...connecting and disconnecting...connecting and disconnecting...connecting and disconnecting...connecting and disconnecting...connecting and disconnecting...
