Motherboard USB Ports Non Functional But Have Power
Dec 21, 2011
The system is built around an Intel Dual Core processor, Asus P5K motherboard running 4gb DDR 2 RAM and an ATI Radeon graphics card. I installed a new copy of Windows 7 Ultimate on a recently formatted hard drive and added and an extra PCI 4 port USB card. My issue is that all of the 6 motherboard USB ports are powered (I can charge my phone from each one) but do not recognise any device plugged into them. Have tried keyboard, mouse, usb drive, camera and so on. Windows doesn't blink when anything is plugged in. When I plug a device into one of the 4 ports on my PCI USB card it installs new device and is working perfectly with absolutely no issues. I have done the following:
- Removed power cable and small lithium MBoard battery overnight,
- Flashed the bios several times upto and including the lastest version,
- Checked that USB is enabled in all BIOS settings,
- Downloaded and installed the latest Chipset drivers,
- Checked that Device Manager correctly sees all the USB ports and drivers. Everything is displayed with no errors or flags.
- Deleted and reinstalled all USB components.
- Windows is fully updated including the language packs.
With my 4 port USB card working perfectly am I to assume I have a biffed motherboard? I just cant understand that as they have power and are recognised in Device manager. And were working perfectly with Windows XP Pro installed previously.
I built a computer this past week. I am using a Logitech K270 and Performance Mouse MX with one unifying receiver. My problem is that whenever I plug the receiver into a USB port on the back of my motherboard the mouse cursor becomes jittery. Sometimes it will stop while I am using it, and then I need to lift the mouse to make it move again. However, if I plug the receiver into one of the USB ports on my case the mouse works perfectly.

Upgraded the bios from F4 to F5 and no effect. Can't see any devices that I plug into these ports. Never liked the transfer rate on these ports when they were working.Very slow - like a standard USB port.
Basically, my HP DV6-3065EA running Windows 7 Home Premium (x64) laptop died. I went into a computer shop and asked how much a simple diagnostic test would be to find out how much a repair would be. He quoted me 90. Phew, jog on! That wasn't going to happen!Anyway, I decided to replace the power jack. No hard job, just a simple unplug and plug back in job. (looks abit like this Hp power jack image by chikyeung on Photobucket). I replaced it; everything is running fine. I tried to put a USB pen drive into a usb socket. Didn't work. Tried another, didn't work. I have tried several devices and they all work on other computers but don't seem to be working on mine. I have been trawling the internet for answers, and as of yet, nothing -.-! I wouldn't call myself a novice, trust me, I've tried everything, uninstalling and reinstalling all of the USB drivers, checking bits of the registry.etc. Nothing. So today, i thought, right, WIPE THE COMPUTER! I backed up everything, went back to scratch.
so i am not intirerly sure this is the correct place to post it.Secondly, i think this is a problem that i have created myself and now i am unable to correct it.The jist of it is this. Whenever i try to active the webcam (Function + F10) a pop-up shows saying that hardware connected to a USB port is not recognized. This must be cause by the cam (which us buillt-in) is connected to the USB port on the motherboard.When i go to device manager, i can see that there is a unknown device connected, whenever the webcam is powered on.Btw it worked fine when i did the initial installation of the computer.What i have tried to do to resolve this is the following:
- Remove all drivers asociated with the webcam - reboot - reinstall from provided CD - Power down, take out batteri (even for en entire night) to let the motherboard reload the USB drivers. - Removed all the USB drivers and have tried reinstallling
I deleted som folders from my D: drive, (which is not the partition that has my windows directory installed) and there i might have deleted som crutial files for the webcam software to work.I have no idea on how to go on from here. This is a computer i have spend quite a long time getting up-2-date with all the programs i use for school and the exams are coming up. I would really like not having to do a clean install right now.
Over the last weekend I installed a new hard drive into my system, and on that drive installed Windows 7 Ultimate x64. Over the past week I have been tweaking my settings, resolving issues, and installing programs.So far everything is working fine, except for the fact that when I shut down, there is still some power being supplied to my motherboard (NumLock indicator does not turn off, and if I open the case the power LED on the motherboard is illuminated). This does not happen when I shut down from Windows XP (I have a dual-boot configuration; XP is on my smaller hard drive).
1. I have gone into my BIOS and disabled all the relevant power management settings (as far as what devices can wake the system, etc.).
2. I have gone through my Windows 7 power management settings and disabled/changed all settings that seemed relevant.
3. I have gone through my device manager and made sure that, for all devices that have a power management tab in their properties, the check box that says something like "Allow the computer to turn off this device when shutting down" (or something like that) is selected. Yes, even for the firewire port. There are some items for which the check box is greyed out and cannot be selected (such as the keyboard).
Here are the only things that I think may have an impact that I have NOT done:
1. Installed the chipset drivers for my motherboard in Windows 7. I have not done this because: a) other than powering down, everything else works fine; and b) I am not sure which driver package I should install (due to the mixed northbridge and southbridge chipsets on my motherboard).
On my desktop, the IMAGE for the recycle bin has disappeared! The text for the icon is showing as normal and I can drag items to the space above the words "Recycle Bin" and then right-click that space to empty it, but no image of it.
So I decided to create a shortcut to the recycle bin on my desktop (through 'create shortcut' button). The icon then appeared BUT only on the shortcut, not the orginal.
how to use the onscreen keyboard. There are a lot of articles that just explain how to start it, but not how to use it.I know how to access it. And it works when I enter letters in the search box of my browser. However, that's all it does. When I use it with a word processor, the keys do not respond. Strange. Also, when i click on alt+(number) on the numeric pad (which works perfect on a regular keyboard), it does not work at all. Don't get me wrong: it's not that I want to type a whole document with it. It should work, but it does not.
HD crashed, been replaced. local tech installed xp, never worked. found Windows 7 clean install info, but cant get past "sorry for the inconvenience" page. want to just reformat the hd, but have no actual working os. tried Killdisk, wouldnt work.what is a good boot disk/reformat disk i can download to start from scratch?
Win 7 Back reads:Windows Backup won't back up the following items:Program files (files that define themselves as part of a program in the registry when the program is installed). Does that mean that the applications contained in the folder Program files will not be backed up ready for a restore when there is a system crash?I want to make a system image for restoring my operating system which will be located on C with applications.
After a reinstall of Windows 7 I got this confusing onboard sound system working after a struggle, but it is no longer able to record streaming audio as it did before; there appears to be no stereo mixer/what-you-hear etc.Windows insists the drivers are up-to-date. During several attempts to get it working, I found at least two different configurations: The first offered a confusing number of line-in and line-out options, the second configuration was a straightforward Line-In/Line-Out/Mic setup - but no stereo mixer.
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've done a lot of searches using variations of the above title and came up empty or just plain missed the answer.I'd like to know, if it is not asking too much, the following points:
1. What exactly is the function of Link State Power Management in the Power Options Advanced Settings, PCI Express?
2. What are the implications of using the options available:
a) Off.
b) Maximum power savings.
c) Moderate power savings.
d) Which option is the best selection for my Dell laptop.
I use my PC for audio production and I have a few external controller devices that are USB powered, for example a midi keyboard. I recently had to build PC due to a theft....long story short after building the new PC I've noticed that my USB buses have continual power to these external devices after I've powered down the PC. My old windows 7 PC did not do this. Is there a setting I can change to shut off power to the USB buses when I power off the PC? Or is this a hardware issue?
i've tried to set the option for pressing the power button to 'Do Nothing' so no body can shut the computer, and yet it shuts down by pressing the button, so why is that and how can i work this out?
Over the past 2 years my PC has been afflicted with random power off/power on/reboot events.It will go for months without these and then have multiples of the events in a day. (I had 8 of them 3 days ago.)I assume I have a hardware problem, but nothing has been found and I'm grasping at straws.The time between power off and power on is several seconds.I had assumed this rules out a software cause, but maybe I'm wrong. I know Windows can schedule a power off, but can it tell BIOS (or something) to power back on in a few seconds?I know blaming the power supply is a much more simple explanation, but then I'm left with explaining the intermittent nature of the failure.
From many days the battery icon is missing from the taskbar, the notification icon is greyed out even if the laptop is not on AC. i followed the the tutorial System Icons - Enable or Disable but nothing happened.
i just finished my build and i have no idea why i went for a motherboard with 2 slots for ram it can hold up to 16gb but luckly ebuyer sent me out an extra 4gb of kingston hyperx ram so i have 8gb all together but theres a problem theres 4 sticks ! obviously i wouldnt want to send it back so what do ya think either upgrade my motherboard and smash the extra 4 gb in there or keep to my original one i dont have money to blow atall im really struggling if its something that will really make a difference ill go with it if not then ill just keep to my original and when i come to buy a graphics card i will get a 2gb graphics card to help with gaming?
My computer wouldn't shut down, even with holding in the power button, and so I just let it run out the battery. Then it wont turn on. I tried holding down the power button to clear out any charge that might be remaining. I have managed to get it back on, but I have to make a connection at the clip where you plug the power button ribbon into the mobo. Also, this is the second time I have had to do this. The computer works fine afterwards...or seems to anyway.
My daughter has a Hp laptop and it was working fine, but the screen was coming apart. so my husband put it back together, Now it will not come on. It's getting some power but not coming on at the power button. The lights flashes when you push the button then nothing.
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.

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
