I have an Intel D101GGC Motherboard with an Intel LGA775 3.0 GHZ processor. They were purchased together on 4/1/2006. All of a sudden all 6 (4 in back, 2 in front) USB ports stopped working. I had a scanner, printer, the mouse and 1 card reader plugged in the back and a card reader plugged into one on the front. My son was using his mp3 player in the other front one - SanDisk- loading some songs on it. After unplugging it the computer wouldn't recognize anything.
He said he went through the safely remove hardware steps when he disconnected so I suppose them not working and the mp3 player are not related I had the yellow exclamation mark beside the Standard Enhanced PCI USB Host Controller and got the message that it could not be started. Anyway, after uninstalling the controller, re-installing SP2 for XP Home and trying other different things - using diagnostic startup, etc this is what I discovered. If I disable ECHI in the BIOS all 4 of the back USB ports will work in 1.1 - however neither of the front 2 will work in 1.1 or 2.0. Can anyone tell me anything else I can try or is this a sign of something more? Thanks in advance.
Desktop Boards Yellow BANG (!) in Device Manager for USB Controller If you are using the following operating systems, refer to enabling Hi-Speed USB 2.0 drivers:. Microsoft. Windows. XP. Windows 2000.
Windows 98SE. Windows Me All other operating systems do not provide USB 2.0 support. If you are using an operating system that does not support Hi-Speed USB 2.0, recommendation is to disable feature in the system BIOS setup program. Follow the steps below to disable Hi-Speed USB 2.0. Disable USB 2.0: 1. Reboot (or power on) system 2.
Press 'F2' during POST (Power-on Self Test) to enter system BIOS setup program 3. Select 'ADVANCED' menu using arrow (left and right) keys 4. Select 'USB Configuration' and press 5. Disable 'High-speed USB' 6.
Press 'F10' to Save & Exit BIOS setup program Hi-Speed USB 2.0 controllers are now disabled and should eliminate the Yellow BANG (!) in Hardware Devices. For addition BIOS Setup program configuration information, be sure to refer to the Technical Product Specification for your Intel Desktop Board.
I have seen things plugged into the USB kill the USB ports on a motherboard. Happened on a really fancy ASUS motherboard. We RMA'd it, Test, Customer picked it back up and Bam!
Dead USB ports again. Once he RMA'd his HP officejet the problem went away. He paid for the third Motherboard he fried the SUBs as he agreed it had to be something on his end.
We put in a USB 2 Card and it has been working fine since. We even Sold him a Custom Vista Ultimate system with 4 Gig memory, 2 Hard drives, DVD burner, NVidia Video, Nvidia dual tuner tv card with remote. Strangely enough we had to order Dell 5.1 speakers to go with it as that was what he wanted.
Bottom line something plugged in can kill the USB ports. Thanks to everyone for sending suggestions. I did try unplugging everything and rebooting - no difference. I've uninstalled and re-installed - no difference. There really isn't any software installed for these things - I just either installed drivers - for printer and scanner and XP installed drivers for the rest.
Media Player 10 was the software that worked with the SanDisk mp3 player. I have taken out the video and sound cards (now using onboard) thinking maybe the IRQs were conflicting - no change. I do have the CD for the board and did re-install the chipset drivers - no change. I am using XP Home and do have SP2 installed so there should be support for USB 2.0. After everything I have done - I don't have the yellow exclamation mark beside Standard Enhanced PCI to USB Host Controller - but when I try plugging a 2.0 device into the front 2 ports I get the message that the USB Device Not Recognized - I take it across the room to another computer and there's no problem - so it's not the device. If I plug any 2.0 device into any of the back 4 ports the computer locks up.
The only thing it will read with ECHI enabled in the BIOS is a 1.1 card reader. If I disable ECHI in the BIOS then it will read everything in all 6 ports, but only at 1.1 speed. I haven't tried plugging the SanDisk back in any of the ports.
I think I'm about out of options other than leave out the video card from the PCI slot and get a USB card that some have mentioned or new motherboard. Will this card enable all 6 ports to 2.0 or is this a card with openings in the back and that is where I would plug the USB devices? If I lose the ports in the front I might as well go with a new motherboard as that is why I got them to begin with - not having to crawl around behind the computer. Thanks again for all of the help and suggestions.
If I consider replacing the motherboard - what are my options? This motherboard has DDR RAM - will that be a problem to get a board that uses DDR2 to work with this processor and still be able to use my Windows XP without buying another license?
I called the place where I purchased it and they said all the boards now are DDR2 - so I'd have to get new RAM and when the RAM and board is changed you would lose Windows XP and have to get a new license. I have a 400W power supply, an 80 and 250 GB sata hard drives, a floppy drive and one CD/DVD RW drive and the RAM is Corsair 2-512 MB PC3200. I work with photography a lot and make DVD slideshows using, 2.5 plus and Tsunami-MPEG DVD Author. I really appreciate the other thoughts all of you have been kind enough to share with me.
If the board is under warrantee, rma it asap. Sounds like an apic chipset issue (power management), affecting the northbridge chipset (video / usb / ect). The problem is common where users do not add up all the usb devices, connected to the pc, to find out the total current drawn from the usb system, and overload the usb supply in doing so.
Its read the manual or else. Most motherboards only have a limit max of 1 amp, but newer boards can have up to 2 amp supply, you need to confirm that with the motherboard manual or from online sources. By overloading the usb current supply, results in damage to the apic chip which controls power management.
It is entierly possible to reinstall the device drivers, and show no conflict, but what you have described is exactly what happens when the apic chipset is compromised. Do not install the gpu until the board is replaced or risk damaging it as well (premature death by overheating).
For those biulding pcs, a note: When you start building a new pc, locate the serial on top of your cpu, and write that info down inside the motherboard manual for future reference (I do for all rma work). See if you can get a replacement through these, would save you the hassles: As for where you bought it from, they should beable to replace it, if they keep messing you about, never go near them again, and advise your friends as well to avoid them.
If you're not ready to upgrade the PC, I would try the PCI USB 2.0 card. Even the ones without the capability of a front panel hookup will work well enough. You could use a USB hub for that, just place the device by the front of the computer. Or get a USB extension cable.
A USB PCI card uses the OS USB drivers, so it's just plug and play, no software needed. Most all newer computers use DDR2 RAM.
If you decide to upgrade, you would need that, a newer motherboard, and I would upgrade the CPU to a dual core. After looking around at the sites that folks here gave me to look into purchasing the same motherboard I saw that this one has a 3 yr manufacturer warranty. I called the place where I got it and mentioned this fact and they said they'd return it for me for the cost of shipping. I may attempt putting the new one in - have read up on it and would like to try.
To be on the safe side with the new board, I'm going to 'remove hardware' from the USB ports when I'm not using the device. Thanks everyone for your help and suggestions. I am going to 'assume' this will fix the problem and it isn't the power supply. If not, I'll be relying on your expertise and willingness to help others again. Keep in mind that removing hardware from the ports when they are not in use will prematurely wear out the physical port itself. I've seen where cheap guy wore out the usb ports on the motherboard because he was to cheap to buy a $20 hub.

I suggest that you know what piece of hardware caused the problem, Son's MP3 player. Only plug that in through a powered USB hub so that the hub acts as a buffer. I mayself have had up to 6 external hard drives that were in powered enclosures, a laptop drive enclosure unpowered, printer and USB mouse plugged in at the same time. It isn't the number of devices it is the type of device. Note on my setup only two were powered through the usb ports the rest were slef powered. Never a problem.I have since simplifed my life and only keep one external drive at a time plugged in thesedays.
Just to update what the final resolution was. I did order the exact same board online and when it came it was DOA. I thought maybe it was my inexperience so I took it to the computer store where I originally purchased the computer and they too did some tests and it wouldn't even boot. I got it from newegg and they sent me a number and label to send it back and said they will give me a refund. I also RMA'd the original board, but didn't want to wait for the time to get it and the computer store doesn't carry them anymore, so I went with an asus p5vd2x as I believe it will meet my needs. I am going to try and sell the replacement board when I get it.
Thanks everyone for your help and suggestions. I believe that was what helped me get this resolved to my satisfaction.
