Hardware Drivers :: Windows 8 Unknown Device Found
May 14, 2013
First my computer when bought came pre installed with Windows 7. As soon as Windows 8 came out I upgraded to Windows 8. My system is BIOS not UEFI. I have about 3gb ram and 500gb hdd drive 2.20 ghz processor. Windows 8 runs really smoothly. So recently 2-3 days ago I decided to dual boot Ubuntu with Windows 8. Before when I had Windows 7 I dual booted it with Windows 8. So now I thought about dual booting with Ubuntu 12.04 LTS. The Installation process was fine until I take out the installation usb with Ubuntu and whenever I try to restart it the PC would hang on the oem screen for a while which is ridiculously long.
Then when I would boot into Windows 8 and sign in I would get a notification message saying the last storage device you plugged in isn't found. I went to the device manager in Windows and it would say an unknown device has been found and even if I tried to Uninstall it would come back again. I tried searching for updates but nothing came up. I googled it and got no results. What annoys me the most is the PC hanging on the oem screen. Right now I fresh installed Windows 8 so it's the only OS running at the moment. But I want Ubuntu 12.04 LTS because of git, ssh and all the server side stuff. I have also posted the error screenshot for more info.
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.
Description:After my pc freezed all of sudden while running emulators (i also had an auto windows update few hours earlier), windows refuse to detect my GPU and NVIDIA installer keep failing...Luckily i have two GPU but i cannot use the NVIDIA one due to this issue.
ASUS Tech Support Little talk with ASUS Support and they asked if i had a critical windows update recently.They asked me to try a system restore, which seem to solve the issue (i could see the GPU card but only for some minutes).Now after that i being asked to format the pc.
I have a Dell XPS 15Z, which I bought off a friend. They recently updated to Windows 8 and so now thats what I have. But when i go into my drivers its telling me that i have an unknown driver. no solutions online have answered my questions though some came close. So, this is what i know:
Device Type: Other devices Manufacturer: Unknown Location: on PCI Express Root Complex
ACPIVEN_SMO&DEV_8800 ACPISMO8800 *SMO8800
i don't know if this is related but my laptop also wont charge. I just bought a new AC Adapter to replace the one i had, and it still isn't charging. The light blinks red 4-5 times and blue/green once. ive searched online to see what the problem is but i cannot do some of the fixes as the computer is at 0% battery.
I'm not truly the best with computers, and this is a new pop up for me. I just purchased this new dell laptop in May and have had no problems with it. However, in the last few weeks I've been getting a new pop up in the right hand corner. My house hold have a wireless router that is password protected. I have McAfee Security Center updated, and shows that all my firewalls and security systems are on and active.
However, this is the message I get and I'm concerned about my networks safety:
"Unknown PC or device detected
This PC or device has connected to your network:
IP Adress xxxxxxx"
I've opened my action center to make sure everything is okay, and the only thing I find that isn't turned on is the "Network Access Protection" - which is something I haven't touched before, nor does it provide a link in which to turn it on.
I've recently replaced my secondary HDD in HP Pavillion dv7 (primary is SSD@W8.1) and as soon as I booted up computer, I got error "no bootable devices found". The first thing that I tried out was bootable USB with Windows 8.1 whereas I ran "automatic repair" several times, without any luck.
Then I opened up command prompt under advanced menu and ran:
I bought a new computer in April, and Windows 8 lasted for about 8 weeks before refusing to start. I managed to get into a dos enviornment and copy my data (about 7700 photos). Who knew that I still remembered xcopy!
Anyway that whole sad story is here:
FILEBCD ERROR CODE: 0xc0000034
I'd prefer to not have to reformat everything and start from scratch (though now that I've ignored Costo and Dell's advice to write off my pictures and do that at the start it is at least an option I am willing to consider).
So I've been playing with bootrec to try and fix my
ERROR CODE: 0xc0000034
Problems. Not that I know a anything about this process. So what I did was:
My (12-year-old) son's computer won't boot. It's a Dell Inspiron 17" running Windows 8, bought from Costco in July 2013. When I turn it on, Dell logo comes on and then in upper left it says "Checking Media [fail]", then "checking media" again, then "No Boot Device Found. Press any key to reboot the machine". I insert a USB recovery drive (it was made for my Toshiba that runs Windows 8.1, but it should work anyway, right?).
I choose US keyboard layout and it then opens into Recovery Environment. I choose Troubleshoot → Refresh Your PC. Message appears "The drive where Windows is installed is locked. Unlock the drive and try again." I go to Troubleshoot → Startup Repair, which runs and then says "Startup Repair couldn't repair your PC." I then go back to Troubleshoot → Command Prompt and run chkdsk on Windows drive (c). It says "Windows has checked the file system and found no problems." Dell would probably tell me it's a hard drive failure and tell me to buy another one.
I have an HP Pavilion TouchSmart with windows 8. Model number 14-b109wm. Yesterday my laptop was working perfectly. This morning when I tried to turn it on I got a message saying, "Boot device not found. Please install an operating system on your hard disk." I clicked F2 for system diagnostics and ran two tests for the hard drive. The "quick test" said "passed." So I ran the "extensive" test and it said "not installed." I dont know what any of this means or how to fix it. I called HP and the lady barely spoke english. She said the hard drive needs to be re-seated. Again, dont know what that means. The F8 and F12 keys dont work either.
I have a laptop Dell Inspiron 15R, which I bought 5 months ago from Best Buy. Yesterday I shut down the computer normally, but when I try to restarted, after Dell logo appeared, on a black screen appeared the message: "Check media..". After a few seconds, on a black screen a new message was shown: "No boot device found. Press any key to reboot the machine".
I've looked on the internet and I saw it's a common error and everybody solved it with "Windows Boot Manager" as a first choice in UEFI Boot List Option. My problem is that I don't have this option. I have only two options:
1. UEFI Onboard LAN IPv4
2. UEFI Onboard LAN IPv6
I press F9 to setup the defaults, I changed to Legacy mode, but no results.
How can I solve Playback & Record device not found in windows' sound?
Sound driver status in device manager still has no conflict and Realtek Audio manager can detect only plugged in jack. I have tried to reinstalled audio driver without any conflict but still nothing in windows' sound.
If I try to restore by windows restore point, would the problem solved?
When I am going to install wi-fi drivers in my laptop , it shows an error of MSI file cannot be found but in system32 folder i can see the msi.dll file,without fixing this error i cannot proceed installation...Here i've attached the error message as an image
I tried many things to fix this but i cannot found the reason for this...Now I am fed up with fixing errors in windows 8......(While thinking move to windows 7 again...)
i accidentally dropped my hard drive its a 1tb buffalo hd-pntu3,,now when i go to disk management in my computer its showing up as disk 1 unknown allocated,,and when i try to initialize disk its greyed out!,,i have a lot of files on this drive
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:
I have two headsets that I've used in the past with ps3, 3 win7 laptops and my iphone with no issues and are still working fine but Windows 8 cant discover them however its finding my ps3, xbox and a cellphone.
Connecting the headsets to the computer with usb shows the devices names but no drivers install.

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.
My laptop took a bit of a fall about a week ago - but grabbed it by the screen before it fell directly on the floor (near miss). Now yesterday, when the mouse pad on the laptop froze up, I drummed on it a bit to get it working and the laptop suddenly shut off and this message appears when trying to start up: BootDevice Not Found. Please install an operating system on your hard disk. I am not sure if it is relevant to the physical damage or if it is software related?
I was listening to music and surfing net on my Windows 8 running HP 650 laptop, when suddenly everything froze.I restarted the laptop by hard pressing the power key. But now at the start-up, the laptop is showing "No OS was found on Boot Drive, please install OS and try again".
When i used the windows 8 DVD for refreshing/resetting it, it says can not refresh because the drive is locked. i tried running linux from a live image, but that linux also does not list my HDD when i use GParted to check.
I also tried doing a fresh installation from my Windows 8 DVD but when it asks for location to install Windows to, it does not show any drive!.
I installed Windows 8.1 build 9471 into my desktop. I use a TP Link TL-WN781ND wireless adapter to access my home network and the internet. I tried copying the drivers from Windows/System32/Drivres and installing them manually, I also downloaded the exe from the site but they still wouldnt connect. It would just say no connections found.
I have a sony vaio pro laptop, originally running windows 8 but just updated to windows 8.1. However, this problem was the same when I had windows 8 so updating to 8.1 has not changed anything. I cannot add my xbox 360 wirelessly as a device to my vaio laptop. I want to be able to stream videos etc from laptop to xbox. When I go to Change PC settings>Devices>Add device the computer searches but will not find the xbox, despite it being switched on and connected to the wireless network.
The really frustrating thing is that I have another laptop running windows 8, now updated to 8.1, and it connects with the xbox with no problems whatsoever. As soon as I click 'add a device' on this laptop the xbox is found and I can connect to it/stream content with no problems.
I have tried disabling the firewall on my vaio laptop, still didn't work. I have ensured sharing etc is turned on on both the laptop and the xbox.
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.
