USB Devices Not Recognized Selectively?
Apr 15, 2011
Out of the blue my win 7 Ultimate SP1 will not recognize CERTAIN USB devices plugged in the rear ports (I have 2 in the front, 4 in the rear). I get the "device not recognized " pop up. The strange thing is, all the the devices that I plug into the front 2 USB ports are recognized and work. I know the rear ports are functioning because when i plug in my scanner, or my flash drive, they work. However when i plug in my HP printer or my logitech mouse (which both work in the front ports), it says they are unrecognized.I have scoured the forums and have tried numerous things; unplugging power, uninstalling drivers, taking out MB battery, resetting CMOS, etc. All with no luck.I really cant imagine how my mouse can work in the front usb port but will not work in the rear one, in which my flash drive & USB-powered scanner work.

I just installed a new PCI USB 2.0 card into my machine. I have a Line 6 Toneport UX8 that connects to the PC by USB as the interface for microphones and instruments. Because of the high volume of data coming down the pipe from this external interface it is pretty much a 'mandatory recommendation' to use a dedicated USB controller in a PCI slot.
Anyway, I installed the PCI card just fine but when I plug in the UX8 to it, Windows 7 reports 'USB device not recognized'. It is recognized if I plug it into one of the motherboard's USB slots though. I need to use this PCI card, otherwise the recording quality is useless. I know other people have this external interface and run it into a dedicated PCI/USB controller with great results. So I am hoping someone here can suggest what I can do to get Windows 7 to recognize the card and the USB devices plugged into it.
I'm hoping I don't have to reinstall the OS since it will be a pain to have to reinstall again when the commercial licenses come out in less than a month (I'm assuming I'll have to reinstall since I will be using an upgrade from my XP Pro that I have not used since trying out this Windows 7 RC).

I have a veho VFS-004 neg & Slide scanner, I have loaded all the software as instructed and although the device shows up in "Printers & Devices" it is not recognized through the program. When I look at the properties in "devices" there is no driver installed and trouble shooting will not fix the problem.

Purchased a brand new Asus USB-BT211 bluetooth dongle with the express goal of connecting a wiimote to my new computer. the machine runs Windows 7 x64, the drivers for the dongle install without a problem, and the bluetooth searching mode on the "add a device" screen appears to be running without a hitch.
when i place the wiimote into sync mode (holding down the red button), it never appears to be visible to the computer, and doesn't show up on the add a device screen. When I attempt this procedure with either of my other two laptop computers, (running Windxows Vista x86) using the same dongle, the wiimote syncs without a problem and can be used with other utilities such as glovePIE and JoyToKey and Dolphin.
So, tell me, Why is it that Windows 7 refuses to see the wiimote when i try to make the connection?

I think one of my hdds is failing and tried to run Seagate tools for Dos that I downloaded from Seagate's site and burned to a cd.The cd loads, but says "no devices recognized"I called Seagate and they said to change to Ide in the BIOS.In researching online, many people are saying that by doing this, you will have to do a complete reinstall of Windows 7.

I have been unable to connect to anything on my wired network, for about the last week. I don't remember making any changes however, I just became unable to connect.I having done a little troubleshooting.1. I can connect to the shares of my Windows Home Server if I use the IP address. The name does not resolve.2. Flushed DNS and restarting DNS server. Flushing DNS works on one client, to allow browsing by the name & restarting DNS works on the other. However neither works after a restart.3. Only my Wifi clients are experiencing this issue. My wired clients, desktops, PS3, Xbox 360, and Boxee can connect perfectly.This issue is not limited to my server. I can't connect to shares on my desktop, nor print to my wired printer.Some network background:I have DSL through CenturyLink and have a Linksys E2000 router.

I have a Zotac 570 gtx connected via HDMI cable to my Asus VE258 LED monitor.I've had this video card and monitor setup working before with the exact cable, card and monitor.Something changed in my system where the monitor is no longer recognized for what it is. When i go into my Nvidia control panel under change resolution 1.Digital Display, 2. DVI-PC Display - Resolution 1080p 59 Hz. There is no DVI cable plugged into the computer and the monitor is set on HDMI input. When i go to my Audio playback devices, the HDMI connection does not show up at all, even as disabled or disconnected.When i go to play a game (Diablo 3, Skyrim, Farcry2) The game either doesn't open (skyrim) giving me the error that resolution is not recognized (but then does not give me any resolutions to choose from in the options menu) or will play (Diablo 3) but is stuck on extremely low resolutions with only 2 options.
Here's what i've done. Contacted Zotac and had them send me the most recent drivers for the video card. Uninstalled originals and re-installed the new ones. Contacted Asus (they say its not the monitor as long as its set on HDMI input) I am unable to find a driver that will make my computer (Windows 7) recognize the monitor for what it is. Zotac failed after their attempt with the driver and told me to RMA the card. So i did... i waited a month.

OK so this is with my sisters laptop, everything was apparently fine one day & not working the next.I've read it may be a driver issue & have re-installed the correct (I think) driver version, but this hasn't fixed the problem.

Since installing Windows 7 Ultimate, Devices has been showing my laptop icon with the yellow triangle/exclamation mark symbol next to it.
When I right click and go to Properties > Hardware the first entry is Unknown Device and it shows the same warning symbol.
The right click drop-down box's Troubleshoot, just above Properties, also has this warning symbol next to it but when I run Troubleshoot it is unable to fix the problem.
Device Manager shows Other Devices > Unknown Device, again with the yellow triangle/exclamation mark.
Right clicking Unknown Device and going to Properties > Details > Hardware IDs shows ACPI/HPQ0006 and on the second line *HPQ0006
I have uninstalled it via Device Manager but it just re-installs when I re-boot and I am back to square one!
My laptop is a Compaq Presario C350EA with Windows 7, 32-bit, installed and as far as I can tell, it is working OK but I am a little concerned about these warning symbols.

windows updated some keyboard drivers or something before i turned off and removed my graphics card to try sort out the heat sink. Anyway, since then my pc has been unable to detect any of the audio ports attached to the motherboard. I've tried various suggestions on other threads but none have worked hence my first post.I understand for any help ill likely need to give more information and ill happily provide such details.

In this tutorial, we demonstrate the new Devices and Printers section of the control panel. This new feature of Windows 7 aims to make it easier to work with and troubleshoot peripheral devices, such as printers, monitors, external storage devices and game controllers. Instead of trying to find your device in a big long list, Devices and Printers tries to assign an icon to it which represents the actual device more clearly.

i have an old windows xp pc that my son uses for chat and homework for printing. the problem i,ve now got is he and a friend of his has formatted the pc and installed windows 7.i do know that some of the devices do not have windows 7 drivers because i once checked when he asked me could he have win 7 on it. i didnt bother to upgrade the pc as there was no need.the problem he now has is that everything works but there is nothing on the monitor. it says no input. i have researched on google and the answer i get is because there is no win 7 driver for the nVidia GeForce FX5200.

I've been having this wierd problem since a few months now.Ever since I reactivated my onboard sound card (I needed to do this since my mic was making wierd noises in Skype) in BIOS one of my playback devices disconnects randomly from the list, but reappears after a restart.This is very annoying as I need that card to use the really good equalizer in my TV which makes my speakers sound great.I have three sounds cards: AMD High Definition Audio Device (From GPU, used for my speakers) <-- This is the one that disconnects ASUS Xonar Essence STX (For music production and headphone listening) SoundMAX Integrated Digital HD Audio (Used for microphone) Facts:
1. The sound card still appears and seems functional in Device Manager
2. The sound card still appears in Playback Devices, but in the "Disconnected Devices"-list
This is what I've tried:- Reinstalling drivers Deactivating/activating devices in Device Manager Installing older drivers I know my way around windows so there's no need to be beginner friendly, I'll ask if I don't understand.

every time I clicked on my devices and printers section, it will never fully load. The green loading bar will only get so far then it would just sit there and not load anything. Also it won't load no matter which path I take. I have tried to research solutions for this matter such as I have tried putting my bluetooth on enabled, turning off my printer spooler and removing ccleaner but nothing has helped.

I've got a brand new Asus G53jw-A1. I took some settings from my old Asus m50vm-B1 when I bought it. Now when I try to print, the G53 is using the settings of the m50vm and gives me an error saying it can't find a computer named m50vm-B1.
I'm hooking up the G53 to a HP Deskjet 6988 via USB and it won't print or even let me go to Devices and Printers so I can delete all the printers and let Windows recognize them fresh.
I tried searching my registry for all keys "m50vm-B1" and deleted them, then restarted.

I upgraded my Dell Dimension 4600 to Windows 7 (clean install on new hard drive). At first everything worked perfectly. At some point, there was an update installed that included an updated Bluetooth Driver. Now, everything works except for my Windows Keyboard and Mouse Elite for Bluetooth. Windows Compatibility Center says it should work with default drivers but it doesn't. I tried rolling back the driver but that wasn't an option so I have uninstalled the device and driver and installed without internet connection so it would only install the native driver (verified by date and version). It still will not work. I have searched many forums including this one, probably tried 12 to 15 different proposed solutions and nothing seems to work. Device Manager says it is installed and working properly but when I go to Add a Device, it does not find anything (phone, mouse, keyboard) even though I have made sure they are discoverable, have working batteries, etc.
So, I went out and bought a new IOGear GBU421 Bluetooth 2.1 USB Micro Adapter that specifically says it is Windows 7 compatible. Per the instructions, I ran the Setup from the CD it came with and plugged in the adapter at the time the setup told me to. It installed all of the drivers and said I was ready to go. After a restart, I went to Add a Device and just like before it will not discover my mouse, keyboard or phone. I went to the IOGear website and downloaded and installed the updated driver with the same results. Still not working. I called IOGear and they stepped me through a few things and still not working. At their suggestion, I took the dongle to another computer that is also running Windows 7. At their suggestion, I just plugged it in and let Windows automatically install the drivers. After a restart I went to Add a Device and it worked perfectly on the other computer. So, their suggestion is to go back to my Dell, un-install what I installed from the CD and from the online update, remove the device via device manager and have it also remove the drivers, restart and plug in the dongle and let Windows find and install the drivers just as it did on my other computer. After doing all of that, it still will not work on the Dell.
So, I am thinking problem with my Dell. So, I boot to Ubuntu via CD and let it install it's native drivers. Bluetooth works perfectly with Ubuntu on my Dell. So, my reasoning and process of elimination, this has to be some setting with Windows 7. Perhaps there is something I did not remove? Perhaps there is a hardware conflict even though nothing shows up in Device Manager?

I've lost all my usb drivers and windows will not connect or recognize any usb device when I install it. Here's the message I get from device manager:Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39). I've tried everything possible to correct the situation even reloading the intel chipset from Asus web site. Windows no longer will detect a flash drive or external usb drive. I'm at the end of my rope and I don't envy the thoughts of a reinstall. Is there a way to reinstall the usb drivers?Any one can point me in a direction.

Whenever I plug a device into a USB port it says cannot proceed without formating the device, even though the device (photo card, flash drive, etc) always worked before. I don't dare format the device because I don't want to lose the information stored. Operating system is Windows 7, 64 bit pro. Exployer 9. Every thing else seems to be working OK except after updating my drivers the other day Exployer 9 seems to have problems downloading many graphic displays from websites. May be entirely different problem not connected to USB problem as that started more recently. USB is my main problem. I work from home so I'm usually around the computer much of the day or evening.

I was having some issues with my pc a few weeks back. Nobody could find a fix for my problem so I took the 11 hr route and restored it back to factory settings. Everything is good except I've got a yellow exclamation point over two devices under Devices & Printers. It's bugging me and even though my initial problem is fixed, I'd like everything tip top after I just put in all this work setting it back up. The error message located in properties is Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19). One is for my printer and I assume the other is for my modem?

The following is an extract from from an Article by Paul Thurrott on his Review of Windows 7
"Devices and Printers Tool
I mentioned this feature in my Windows 7 Beta review, but I'd like to point out again that it's not just Device Manager for Dummies: This new Windows 7 feature can actually find and fix problems with your PC. And it really works. I've used this feature to find missing drivers on two different PCs now, and in both cases a similar search via Device Manager netted no lover at all.
Here's how it works. Launch Devices and Printers (use Start Menu search) and locate any devices with a yellow bang graphic on its icon. Right-click and choose Troubleshoot to launch one of Windows 7's stealthy new features: A troubleshooting infrastructure that links back to Microsoft's data center to always provide the most up-to-date help. The troubleshooter will detect the problem and look for solutions.
And while I can't claim a 100 percent success rate quite yet, it's certainly worked better than device manager: I found a biometric driver and fixed a Bluetooth problem on my laptop, and found a system management bus driver on my desktop using this tool. Nice!

I am having an issue with accessing the Devices and Printers page in Control Panel. Each time I click on it-it never loads (look at the screenie to see my point). This may be due to an issue with my Bluetooth drivers. They install successfully but they can never find a device nor can I open any settings page for the Bluetooth. If anyone can help I would be eternally grateful. This is what is keeping my Windows 7 experience from being perfect.

This is what My Computer looks like:OS C: is the primary internal HD.Local Disk L: is my 320GB external HDD.DVD RW D: is my one and only CD/DVD drive.E:, F:, G: and H: drives are non existent as physical drives installed on the computer, but they appear as options within the menu. How do I get rid of these if they don't even exist?

Are the icons in the Devices and Printers window (Device Stage) replaced immediately upon any system update, or do they just show up and get replaced at random whenever Windows 7 feels like doing it?
I recently did a fresh install of Windows 7 on two different machines (Ultimate x64 on one machine and Enterprise x64 on another) and the devices listed show the stock icons even though the drivers for those peripheral units are installed. All "Update" settings are set to recommended and automatic on both machines.
Weird thing is before I re-installed Ultimate on the first machine, the true icons showed up in Devices and Printers for my monitor, keyboard (MS keyboard), Canon scanner, Brother printer... I didn't quite pay attention how/when that happened, but I was pleasantly surprised with the extra access I had by just clicking that life-like icon.
Now, since the re-install, all I get are the stock icons.
Funny thing is when I hit "Properties", say - for the keyboard, which is a Microsoft 3000 kbd, the info simply reads: "Unknown Manufacturer", "HID keyboard Device". The MS drivers are installed though.
Same thing for my monitors (Dell 2209WA). Windows downloaded the drivers, but the properties info shows the monitor as "unknown manufacturer". How weird is that?
Something I'm missing? Or is this Device Stage fubared somehow?
