Unknown device HP Envy windows 8

After upgrading an ENVY 4-1043CL to windows 8 (including upgrading bios), an unknown device is detected in control panel, and the system can't find a driver for it after numerous scans. How do i determine what the device is so that i can download the appropraite driver? I have also tried to use "auto detect" from the HP web site but that process crashes IE.

After further research I found it, it's the HP wireless button.

Windows 8.1 - Installed from scratch.
I was able to install and configure all drivers but one. I found a tread that suggested installing Lenovo Setting Dependency Package 2.0.0.13 to fix it on a different lenovo model. I tried it without any success.
The driver id of unknown driver is "{48126E0D-4BDD-4D26-8A24-569C7AB522D6}\SettingsDriver"

"Unknown Device" shown when I connect my iPhone 4 to the laptop

Hi all,
My iPhone 4 cannot synchronize to my Windows 7. Only "Unknown Device" shown on the "Device Manager" when I connect them via the cable.
The laptop is new and installed Windows 7 Home Premium Edition 64-bit. BIOS is the latest one.
iOS is 4.0 and iTunes is 10.0.1 for 64-bits Windows 7
I do not think the problem is due to the iTunes. Only "Unknown Device" shown on Window 7. I think the iPhone cannot be recognized by the laptop.I tried to connect the phone to a Window XP. It is fine. Likewise, a usb drive is recognize by the Windows 7 laptop.
I have tried
1. update the BIOs
2. Re-install the itunes
3. download the usbaapl.sys
Can anyone help as it bother me for a week.
Thanks very much
Ben

The first thing I would try is to use a different USB port
next I would have my MacbookAir looked at

Unknown device in device manager after win8.1 upgrade W540

I'm using the W540 with an ultradock and external monitors. After upgrading my W540 to win8.1 64 bit, device manager is showing an unknown device. I'm not quite sure what it is, but almost everything seems to be working fine and Lenovo solution center isn't finding any driver updates.
I did notice that the solution center hardware scan did not test the video card memory and listed that test as N/A. Video and monitors seem to be working fine though and both nvidia and intel graphics show up in device manager.
Device manager lists the device in question as follows:
Device instance path: ROOT\SYSTEM\0001
Hardware Ids: root\iwdbus
Device stack: \Driver\PnPManager

Envy 700-230 Unknown Device

On my Envy 700-230 Desktop PC, there is an Unknown Device with a yellow triangle next to it. This occurred after installing Windows 10. What needs to be done to remove the yellow triangle?

Hi: I have never come across that device before. The only thing I could find was this thread with a related device. http://rog.asus.com/forum/showthread.php?37535-An-unknown-device-discovered-while-installing-drivers-for-the-Maximus-VI-Formula If indeed that device needs the Intel Widi driver, then here it is below. https://downloadcenter.intel.com/download/25153/Intel-Pro-WiDi-Software-for-Windows The product specs for your PC indicate it is Intel WiDi capable, so not having the driver for that device makes sense. If that doesn't work, unfortunately, I don't have any other suggestions for you to try.

Equium L10: Windows Vista Beta2 - unknown device

Hi
I have a Toshiba Equium L10 with Windows XP loaded as default but I installed VISTA Beta2 "public release" on it and given that it's only a 1.5GHz Celeron CPU with 512MB RAM, it ran extremely well but, I have one problem which I am hoping that I can get help with from the users in this forum and especially those who have the same/similar Equium model as I have?
Ok, after installing VISTA I checked in Device Manager and noticed "Unknown Device". After checking out the info given in it's properties, I have detailed it below:
Location: Microsoft ACPI Compliant Embedded Controller
Value: ACPI\ACPI 0001 * ACPI0002
When I re-installed XP again, I went to Device Manager/Batteries/Microsoft SMART Battery, the entry for Microsoft SMART Battery Subsystem has "ACPI\ACPI0002\6&28CA2229&0".
Notice the "ACPI0002" info given for the 'unknown device' in VISTA is the same info given for the "Microsoft SMART Battery Subsystem" in Windows XP. So I am left wondering if the unkown device under VISTA is the Microsoft SMART Battery Subsystem and if so, why did VISTA not install the driver for it?
Can anyone help with find a driver for the "unknown device" in VISTA?
Regards
Brave

Hi
The unknown device appears because the driver is missing.
Unfortunately, at this time you will not find any Toshiba supported drivers for the Windows Beta2. This is a beta version and not official on the market.
I think if this OS will be official supported so you will also find the needed drivers.

Unknown Device ipod Classic and Windows Vista problem??

Help!! My ipod Classic is not being recognized by my computer. I have read the previous articles and tried the solutions but I continue to get the result "Windows has determined that the driver software is up to date" I continue to get the error noise when I plug the USB in and the Device manager continues to say "Unknown Device" It seems others are having this problem, how do I fix this?

I am having the same trouble with mine, and I can say that it isn't iTunes, I plugged my brothers iPod Nano in and it worked like a charm, but when I plugged my iPod Classic 160g in all it says is it is an "unknown divice". It isn't Vista either as the same thing happens on XP Pro as well, so all I can think of is it is a error on the Classic itself. I just wish someone can help out so that I can use my ipod!!!! Come on Apple!!!! Solve this problem!!!!

Unknown device - ipod nano fine - problem with windows xp and usb root hub

Greetings all. I've seen this question come up over and over again and have been working on it following previous posts and posts on microsoft and hp sites for a couple of days now.
First off - the ipod nano is fine. Works on my son's computer well.
When I plug it into my 6 months new HP Pavilion laptop it says: 'found new hardware' and goes through the process of installing it, says it's been installed, but then shows 'unknown device'. In Device Manager it tells me there are no drivers installed, but when I try to follow the other instructions on this forum to update the drive to USB mass storage device (usbstor.inf), it tells me the best driver is installed and won't do it.
Many seem to have this problem with devices other than the iPod on Windows service pack 2 so I went to the Microsoft forums and they seem just as puzzled. I've updated all my Windows & HP software to the latest possible versions. The problem is definitely in the USB. Once, when I uninstalled the USB device and then rebooted the computer with my iPod still plugged into the port, it found my iPod, correctly identified it, and for a blissful moment I thought everything was fine! Then it reinstalled the USB drivers and made a comment to the effect that I should move the iPod to a USB 2.0 port for more effective operation and the iPod disappeared again.
I have 3 USB ports on my laptop, all are USB 2.0 and all 3 have the same problem.
I've tried all the stuff people have already said on here...does anyone have any NEW ideas? I'm hesitant to take it in for service because it seems to be a software problem that should be fixable.
Thanks in advance for your help and sorry about the long post.

This isn't a solution, but it's something I just tried and it may provide someone additional clues about's going on. I too think this is some sort of USB problem.
I have 6 USB ports. Two of them are USB 2.0. Since I applied the 03-23 update my computer hasn't recognized my nano at all. I would connect my nano and I couldn't get it to show up in My Computer, in iTunes, or on the far right side of the Start taskbar.
I just tried plugging my nano into the first USB port of my USB 2.0 pair and left the second 2.0 port empty. I then rebooted with the nano attached. Viola - I get a "Found New Hardware Apple iPod USB Device" message. My nano is now flashing "Do Not Disconnect." A small removeable storage icon with green arrow now shows on the far right side of the Start taskbar. If I click on it (like you're going to eject it) the note displayed says "Safely remove USB Mass Storage Device - Drive (F:)".
If I go into My Computer, "Removeable Disk (F:)" now shows there. However, if I try to follow Trevor's instructions in another post to "go into My Computer with iPod connected, right click it, wait till the right click menu comes up (could take a few minutes); click Format, . . ." I'm stuck. I do the right click, watch the hour glass and wait for the Format menu to come up but it never does. Eventually the hour glass just goes away. No message, no Format menu. The waiting hour glass just goes away.
My computer isn't as new as yours, but like you I am completely current on maintenance.
I'm going to keep trying . . . If anyone has any ideas, please let me know.

G555. Need drivers for SM Bus and another Unknown device for Windows XP.

I try to install Windows XP on my G555. I got all other drivers, but cannot find drivers for SM Bus and an Unknown device. And what's this device?
The second problem is that after I installed all the drivers, the card reader disappeared. It was there after I installed Windows XP, before I install drivers.
Thanks a lot.

Hi Simpleguy,
Welcome to the forum!
In thinkpads, it's usually intel chipset driver. For AMD based G555, I wouldn't be surprised if this is the driver you need:- http://consumersupport.lenovo.com/us/en/DriversDownloads/drivers_show_2476.html
As for other unknown device, find it's PCI ID with any other known information and paste here.
Hope it helps.
