Device Manager Reports Unknown Device & Explorer Crash
Aug 1, 2009
How do i figure out what driver or even component windows wants software for when in the device manager under other devices it lists an unknown device and windows update cannot find anything.
Oh and is it appropriate for me to use this topic to ask another question regarding explorer.exe as while i am inside a folder i delete (by choosing delete from the context menu in the tree view) while inside that folder on this particular laptop PC explorer. always crashes, collect information, sends it and restarts explorer. I have not experienced this problem on any other pc running any version of windows 7, oh and the same happened with build 7264 x32 and the current install of build 7600 x64.

I got a new hard drive for my HP Pavilion DV6T-6000. Installed windows 7 ultimate and a bunch of drivers from HP's drivers section for my computer and I still have this unkown device. It wasn't there on my old drive so something isn't right here.
Location: on Microsoft ACPI-Compliant System
Status: The drivers for this device are not installed. (Code 28) There is no driver selected for the device information set or element. To find a driver for this device, click Update Driver. Hardware ID:ACPIHPQ0004

Have recently purchased a small usb inspection snake camera with led light and when testing it plugged it into two desktops computers (one xp pro not sure of the other as it was a network work computer) It automatically loaded the drivers and brought up a screen automatically with the realtime image.(no driver disc came with it). However plugging into my windows 7 64bit sony laptop it signals a connection beep, loaded drivers automatically but wouldn't open or show up on my computer disc manager as an external usb source to click on. It does however show up on device manager as a usb camera and when I unplug and replug in it disappears and reappears so I know I have the right camera (not the lap top webcam inbuilt one that shows USB 2 Camera). Have tried updating drivers automatically and uninstalling it etc. Need it to work on the lap top so it can act as the movable screen for it?

When I disable the network controller in Device Manager, the controller is disabled but nothing changes in Device Manager to identify the device as being disabled. When I used to do the same thing in Windows XP, the device icon turned yellow. Is there some setting to identify disabled devices in Win 7's Device Manager?

I got a new Dell Studio XPS 13 laptop a week or so back, loaded Windows 7 RC and everything worked fine after a bit of fettling here and there. On Tuesday or Wednesday I had a problem where the laptop locked up while using a Logitech USB Radio mouse. Thinking the mouse caused the lockup, I disconnected it and have been using the touch pad since and no lockups. So far so good.
Then today I plugged in a set of Logitech USB headphones for Skype and I got an 'unknown device' error. I tried with other USB items, ADSL modem, memory stick, all had the same problem on both USB ports and nothing I did would solve the problem. Much googling and a search of this forum again came up with nothing I could use.
I then had a flash of brilliance - I figured it must have been the mouse that started the problem when the laptop froze and somehow something was blocking the USB useage. I plugged in the mouse whereupon it loaded up the software and worked fine, and now everything else loads up and works OK too!
I can't explain it, I'm just a programmer and don't really understand computers but if it helps anyone else in the same frustrating situation, there it is.

I have installed Windows 7 RC on 3 computers and setup the network as a home network, skipped creating "home-group" I have 2 XP systems on same network that I need to access. Anyway, I cant seem to figure out why/what this unknown device in my network map is? It shows up on all the computers that have the RC installed. I have attached a pic of this.
Any ideas?

I just bought a new ASUS computer with Windows 7. I have a Macbook Pro and would like to transfer my photos and music onto my new computer. I have 2 external hard drives that work perfectly fine on my mac as well as other PCs. When I plug either of my external hard drives in they are recognized in device manager and say they are working properly but are not recognized in disk manager or under my computer...

I had an "unknown device" show up in devices and printers a couple days ago. It was also listed in device manager and said it was a USB controller. Everything worked and I've not added any new hardware. I have 2 partitions both with Windows 7 and the error showed in both. I've found that others were having the same issue, some needed drivers, some said cables needed replaced. Before I got serious with the troubleshooting, I read up a little and found a forum that said you should shut down then disconnect the power cord, wait a couple minutes then power up. Sometimes the motherboard needs to reboot and the devices will be reloaded or reassigned as they should be. It worked for me, it was an easy fix to an annoying problem.
