Certain devices ("obsolete" flash drives, iPod) are undetected in Windows 7. There are no problems with my mouse and wireless adapter, which are USB. I have tried connecting previously undetected devices through the same ports that detect the mouse and wireless adapter, which has made me further suspect the problem being with the ports, thus possibly drivers, rather than the devices (since the devices are still undetected).
I have also tried uninstalling all USB ports in Device Manager before restarting Windows, which didn't help.
Another related concern is whether the motherboard driver(s) is(are) up-to-date. I have an Intel Desktop Board LGA775 and cannot find the proper download for an update. This may fix the problem.
I have Logitech Performance MX mouse. It used to work fine until somebody installed other mouse on my computer. Since then mouse was randomly disconnectign and reconnecting every minute.I managed to fix that now mouse is stabile but even though all drivers are installed it is seen as HID mouse and not my Performance mouse - so i cannot for example see its level of batter load.The other problem is there is loads of extra identified USB controlers and mouses even tho i have just connected 1 mouse, 1 keyboard by other USB port + 1 external HDD. Thats just 3 USB slots total.If i put pendrive into computer, then mouse keeps disconnecting againIf i turn on 'shield scannign devices' then after puttign USB into drive i have 3 seconds to click 'not scan it' if i do that, it wont be disconnecting. Yet turning off scanning makes mouse disconnecting on putting extra pendrives.Here is what i tried so far:@ USB Driver - General Fix for@ Turning off windows shell scan [to not auto scan devices].@ Chaning ports, upgrading bios etc.@ RUnning windows 7 USB problem fixer. It is turning off
My USB 3.0 ports aren't working. I have 2 USB 3.0 front ports that are hooked up to the motherboard and 2 addition USB 3.0 ports back ports pre-installed on the motherboard. None of the four can detect my USB 2.0 devices. The USB 2.0 ports works fine.
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.
dell xps gen 4 running windows 7 (32 Bit)after downloading the latest windows updates, front and back USB ports no longer recognize the USB devices that were plugged in before. The usb device drivers no longer automatically load. usb ports recognize unknown device but device does not function (USB wireless Keyboard/ mouse or external hard drive) I deleted last few updates, re-booted computer and still get same result.
I no longer show any storage media (flash,portableHD) in my computer when i plug them in. The sound chimes when they connect, they show in the device manager with an exclamation point, but i cannot access anything. Initially my flash drives would attempt to install drivers but fail, now nothing even pops up in the task bar to show it is connected.
Anything that it not storage related (mouse,keyboard,printer,phone charger) all work fine, they chime and pop up in the taskbar when they are plugged in like normal.
What i have tried with no success: Boot into safemode and uninstall everything under USB Controller.... in the device manager including hidden, use different usb ports, refresh, update drivers, nothing works.
recently, in my Win 7 32 bit SP1, USB devices like keyboard and mouse are getting undetected and detected every now and then. Troubleshooting shows "hardware changes might not have been detected". All the drivers are up to date. Sometimes the computer showed that there was a power surge in the USB hub. I think the USB hub is losing power every now and then
OS is windows 7 ultimate 32-bit/i am using high definition audio device from Microsoft speaker, mic and headphones are working front panel and back is also working..my speaker and the mic from this headset is working, but when i tried to use the headphones and the mic together, the headset is not listed or detected in the playback devices! i cant set my headphones to default because it is not displayed,and when i tried to unplug my speaker,still it doesnt recognize that i have my headphones plugged.i tried install my sound device(VIA HD audio device ) my speakers and headset are working at the same time but my mic is not recognized, but when i uninstalled it, i got my first problem regarding the sound devices but when i installed Realtek, same result with the first one that Microsoft is my audio device.
I formatted my new Satellite l855, and installed windows 7 instead of windows 8. See what is going in device manager. Screenshot:
Network devices are not detected at all (ethernet, and wireless). My AMD HD Radeon 7670M isn't detected I don't know what's going with those unrecognized devices (yellow) it's a new laptop, i just formatted it and installed windows. What should i do?

A few days ago I installed a USB 3.0 card (to be precise, this one: 2-Port USB 3.0 SuperSpeed PCI-E Controller Card - Free Shipping - DealExtreme). It uses the very common NEC PD720200 USB 3.0 controller. I installed the required drivers for Windows 7, and the card worked fine for the first day or so. but not since. Whenever I plug in a USB 3.0 external hard drive, I get a false "This device can perform faster..." message, as if I had plugged the drive in a USB 2.0 port.
The external drive I am using is a Western Digital MyBook Essential 1130. It is definitely a USB 3.0 drive, and came with the required USB 3.0 cable. While the USB 3.0 card was working, I got full-speed transfers to the limit of the hard drive's ability, about 90-100 MB/s. Now I can only get USB 2.0 speeds (33-34 MB/s). Windows insists I have the drive plugged into a USB 2.0 port even though it is plugged directly into the USB 3.0 card.
Things I tried so far: -rebooting and complete power cycle. No difference. -plugging the drive into one port or the other. Also no difference. -Looked in Device manager.The controller is recognized as a USB 3.0 device is using the proper NEC drivers.
Other info that may be important:
-No overclocking settings in use.
-I made sure the cable was plugged in all the way. It's in as far as it can go, but the ports will still only act like USB 2.0 ports.
I might as well throw the card away if it is only going to act as a USB 2.0 device.
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 recently bought a USB to RS232 adapter (it works fine). My question is: How can find out which com port it is using, except by trying all of them and then finding the one that works. I have a older Thunderbird GPS 10 MHz frequency standard thet requires a RS232 interface to talk to it (for setup purposes). The first thing it askes me is which com port I'm using(1-16).
My USB ports on this Gigabyte mobo are SUPPOSED to be all USB2.0
So, how come I still get "This device can run faster" messages in
my Windows 7 64 bit home premium installation?? I went to Gigabytes webpage and installed the chipset drivers for Windows 7 on there, but still get the same message when I plug in my Corsair 4GB jumpdrive.
System - Dell Inspiron 546, Windows 7 Home Premium x86 64 bit.
I'm an Engineer/Designer/Machinist and work with CAD/CAM programming. After I create the programs with the toolpaths for my CNC Macining Center I use a separate program to transfer the machine control data to the CNC.
Here is my dilemma - Win 7 is not compatable with the old 16 or 32 bit, file transfer program I had been using with XP and Vista. I have found 64 bit programs that are compatible but cannot get the computer and CNC to communicate.
The problem I'm having is, in the file transfer software I need to set the Parameters such a Comm Port, Baud Rate, etc. I cannot determine the port assignment for the usb connections. In XP and Vista they were Comm 4 and I could find that in Device Manager/Ports. Win 7 doesn't seem to have a listing for ports. How do I determine this.
I have five USB 2.0 hub successfully operating over 20 devices. As these fail I will upgrade to 3.0. Anticipating more 3.0 devices and a 3.0 motherboard in the future. Why do they only have four ports? If I am mixing 2.0 hub with 3.0 hub's should I plug in. In a certain order
So I installed some weird file and it like disabled ALL of my USB ports, hwo can I get them to work again?! Both my keyboard and mouse are USB and I don't have any regular ones, any way I can fix this through my 2nd partition using WinXP? im using the Win XP partition to ask this right now, my Win7 partition seems to run fine like when it happened I thought it froze but it didn't because the wifi signal went off from my USB wireless adapter and my mouse+keyboard adapter both light off as well as my DVC 80 capture device. The file I ran was 'libusb-win32-filter-bin-0.1.12.2.exe' from a package I downloaded in a zip called 'iHackintosh iRecovery Package for Windows & Mac' and I REALLY DONT want to restart my computer
I restarted my computer to return to the login screen and found i have no control of my mouse or keyboard.I have control before Windows loads (in Bios Settings).I have enabled and disabled in every combination possible for the settings of the USB in Bios Settings.I can not system restore. I have no control in safe mode.Basically if it deals with windows, i have no control. Only before windows loads.
I noticed recently that for some reason,my USB ports aren't being identified as 2.0 ports, but I know they are. My computer is an ASUS CG5270, Specs: Core 2 Quad @ 2.4 GHZ,8 gigs ram, 750GB hard drive. I tried going into the device manager and uninstalling everything under "USB", and then restarting and replugging everything in..no luck. I found some Fix for Windows 7 SP1...no luck. Whenever I go into the Device Manager, there are two ports ( I think they're ports) listed as "Enhanced", with the rest as "Universal". I keep getting errors when I plug in my external HD that "this device could perform faster". (I also get another message telling me that the drive needs to be formatted, but it works anyway). I also get a "this device could perform faster" with my webcam, as well...
When I plug a USB device into my laptop it doesn't recognize it Shown Here: Rec008.avi - download now for free. File sharing. Software file sharing. Free file hosting. File upload.
first of all i would like to excuse for my rusty english... passed some time since i last wrote something completely in english ;-)
i'm using the x86 version of build 7000 and i'm very fascinated of how it works already in this beta-stage. but i have a strange crashing-issue from time to time that does not allow me further testing.
from time to time all of my usb-ports seem to block everything: my usb-soundcard stops working, my wireless-adapter, my external hd, everything that's plugged-in into an usb-port stops working.
it happens when i'm using my soundcard, videocard or both of them: playing games, watching dvds, browsing Internet, listening to music, etc.
when i'm trying to reboot, the os will stuck in the logging-off-screen 'cause it's trying to play the logoff-sound over my soundcard..
On my Dell Vostro laptop, Up until today I never had a problem but now when I plug in my energy monitor to a USB port I do.. I have a mouse plugged in one port. If I plug in my energy monitor into any of the other 3 USB ports it installs a USB to serial port at the next higher com number. Its up to com 18 now. If I unplug and replug it in again it will find USB to serial com 19. It just keeps going up. How can I reset it back to 3 or 4.
I want to disable some of the USB ports in my W7U-64bit Ultimate system.Normally I do this by viewing in HWINFO64.The after in DeviceManager to uninstall the wanted USB ports.But now I cannot see the adresses in HWINFO64 nor in DM.
as soon as i connect anything to the usb port, i get the message "usb device not recognised". i have tried to go back to various restore points but these all fail to complete.
I am not going to tell my problem or trouble but rather to tell what I had done based on what I found out from other responses to "related issues" subjected above.I just thought that I must do this for the sake of others, brothers and sisters in Jesus Christ wanted to go back to the threads that his but I am not that fond of using the search fields and somehow my google search results on this lappy is quite differ from the one i got on the usb-troubled lappy that i used to log into sevenforums. i have read through just about 10 of the related result on sevenforums but not one of them is the one i found out earlier.anyways, what i did was: uninstalled all usb listings in device manager and then just shut down the lappy, unplug all cables including power cable and went out for a smoke. a few minutes later, came back and plugged the power cord and turned on the lappy. and somehow, windows auto-install everything and since the lappy is wirelessly connected to the internet like always, it also download and install everything.then i plug the main cause of the problem (microsoft 5-button intelligent mouse) and wait for the driver update wizard to complete; and now everything not only seems working fine, BUT actually working fine now.
I cant open my ports. My router has DMZ enabled and I have disabled windows 7 firewall and disabled the firewall in ESET Smart Security 4. PORTS STILL WONT OPEN!
I am running windows 7 ultimate x64after booting the pc and without visiting any website when I scan my machine localhost using command nmap -sT -O localhost[CODE]
I just installed Windows 7 tonight and thus have moved from the Vista forums to here
But of course if everything were going smoothly I wouldn't be here. Now here's my problem, I'm trying to open ports for some of my programs but I havn't been able to. I've done it many times before in Vista with no trouble. I've tried disabling the firewall to see if that worked but it didn't.
Now here's where it gets weird. When I was in Vista I'd use Open Port Check Tool to check if my ports were opened correctly, it always worked. But now when I try it it tells me that my ports are closed, even basic ports like 80 and 21 keep getting:
Error: I could not see your service on 76.68.106.153 on port (80)
is there a program that can show me the exact ports that an aplication or all the aplications on my computer use, or is there another way to get the information.
