I am using windows xp sp2 professional.few days back my usb ports stopped working suddenly.They don't recognize any usb devices.Also there is nothing like usb controller or usb ehci in the device manager.I don't have anyway to know what has happened.The motherboard is intel 845 gvsr.If you have any links for updating the usb driver or the bios or any solution to this
View 2 RepliesI have lost access to all the USB ports on a PC. There was no apparent crash but I realised there was a problem when the USB Mouse stopped working. Everything else is working OK. I get an Error 39 (drivers corrupted or missing) and the 2 entries in Device Manager both have yellow marks against them. I only have "Standard Enhanced PCI to USB Host Controller" and "Standard OpenHCD USB Host Controller" entries below the entry for Universal Serial Bus Controllers - no Root Hubs are there and there are no Unknown Devices anywhere else.I was running XP Pro SP2 when the ports went, but have installed SP3 and Updated to see if that did anything - it didn't. I have tried the troubleshooting suggestions on Microsoft such as deinstalling and rebooting, updating, system restore and have done a repair installation using my original XP SP2 disc all with no result.
View 9 Replies View RelatedMy CPU has been 100% for over a month. I first thought it was a virus so a scanned w/ every program out there and nothing would detect anything, HJT log was reviewed and nothing found so I went down the Registry Path and tried to repair with Registry Repair Tools to no avail. So I backed up all my files and did a complete OS re-install in CPU is still at 100%. And when this problem first started by USB ports stopped working.
View 6 Replies View RelatedI've got a bit of a problem with my computer and was hoping some advice. Basically all the USB 2.0 ports on my computer have recently stopped working - I can still use them to charge my iPod, but not to communicate with it (I no longer get the little icon in the bottom right hand side of the screen when it's connected), and I can't use my printer because the computer insists it's off-line (I've tried two different cables so it can't be a problem with that).I've got two USB 2.0 ports on the back of my computer (built into my motherboard - can't remember the exact model offhand but the processor is one of those 2800+ Athlon 64bit ones, if that?s relevant) and I've also recently upgraded my monitor to a dell FPW2005, so I've now got another couple (not working) on the side of that too. I even tried taking the USB 2.0 card from my old computer (that has 4 USB 2.0 sockets in it and plugs directly into the motherboard) - but this didn't work either
View 3 Replies View RelatedI have a Sony VGN-T1XP Vaio laptop with an Intel Pentium M Processor running XP Pro SP2. For some reason the two USB ports have stopped working and no USB devices are recognised. I have looked at the device manager under USB controllers and there are four USB controllers listed which are as follows: Intel 82801DB/DBM USB 2.0 enhanced host controller 24CDIntel 82801DB/DBM USB universal host controller 24C2Intel 82801DB/DBM USB universal host controller 24C4Intel 82801DB/DBM USB universal host controller 24C7 Underneath those are four USB root hubs.
I have previously used a USB card reader and external hard drive on both ports without any problems but now when I connect any device nothing at all happens.
i just reinstalled xp on my laptop and now it wont show up anything when i insert something intothe usb port. the light comes on on my usb stick. but thats all. i checked the usb controllers and the hubs and it says the device is working properally.

View 14 Replies View RelatedSince upgrading to Windows XP Service Pack 2, my network adapter (a 3Com 3C905-TX-M)does not appear in Device Manager and I therefore can't get this computer to appear on my home network. The network adapter is still working because that's how I connect to the Internet, via LAN to a router then cable broadband,and IPCONFIG gives valid results including the correct IP address from the router via DHCP.I installed a clean copy of XP Home on a spare hard disk. The network adapter appeared in Device Manager and the computer appeared on the network. I then upgraded to SP2 and the network adapter disappeared from Device Manager and the computer no longer appears on the network.

View 1 Replies View RelatedI had some trouble last night and today with getting rid of a virus. Now that it is gone, I am having sound problems (maybe related, maybe not). This morning, when I opened iTunes I got a message that there was no audio device detected. After trying several things, I rebooted. Magically, I could play music again. However, a short while later, I again got an error message telling me that there is no audio device found, even though it shows up in Device Manager as working properly. The problem goes away for a short time after I reboot, but returns. It is Realtek AC 97. Why won't my computer keep recognizing it? (It tried going to Realtek's site to download an update. It has updates for Windows 98, 95, etc., but not for XP. Or at least I couldn't find it.)

View 10 Replies View RelatedI had this problem last time when I fresh installed Windows XP Pro on my computer. I don't know the time, but it happens at least 30 days after I reinstall the OS and software. Today, my computer prompted me to install drivers for a PCI Input Device, but I haven't installed any new hardware for months. Basically, I haven't touched the inside of my computer for that long. So why is Device Manager prompting me to install this mystery device? Hardware ID shows that it is from vendor 1102, which is Creative, and I have an Audigy 1. Also, my FireWire port is Code 10, the device cannot start. So I'm thinking the mystery device is the same firewire port. But why show up as a separate device? I tried removing the devices and restarting the computer, but they return to haunt me again. The device properties for the PCI Input Device says PCI SLOT 7, AND I DONT HAVE A 7th slot! Can someone help me, please? Device manager shows my 1394 Net Adapter with a yellow exclamation, and it has code 10, device cannot start. There is an unknown device, the PCI Input Device, which doesn't allow me to install any drivers for it, yet it has the creative Vendor ID 1102. It shows itself as being PCI Slot 7.

View 3 Replies View RelatedA friend of mine has a 4 yr. old PC running XP Home with 128Mb of memory. He's had problems with programs aborting recently. I tried to run Device Manager to make sure there were no issues there. It briefly brought the screen up, then it went away. The same thing happened to Task Manager when I tried to see what was running and how much memory was being used. Anybody ever see this behavior before? I might try installing a memory cleaner pgm (ie. Memturbo), but I'm not sure I would even be able to get it to run. The hard drive amd memory seem to have no errors.

All my stuff is working, so I don't know where this critter came from?

I upgraded from Windows Me to XP-Home a couple of months ago. I expected several things to be different, but in a GOOD way, ya know? There are a few things that don't work as well and I'm wondering if it's just me, or is it the program? It takes much, much longer to start up and shut down now. I've taken the unnecessary things out of the Start Up in an attempt to speed it up, to no avail.
In Me, when a program would stop responding, I did Ctrl-Alt-Del, and the task manager would pop right up and allow me to end the problematic program in a reasonable length of time. In XP, when I do c-a-d, it takes up to two minutes for the task manager to pop up....then when I click on the bad program line and then click on End Now, the little End Now box pops up, so I click on that and the little box goes away, but the program I'm trying to kill keeps going. I've seen it take up to four minutes to stop a program. There have even been times that the End Now box stopped responding...
I have a machine which has suddenly stopped responding to any mouse connected to the usb port. The ports appear to still be working as i can access a usb key etc from them. As soon as i plug a mouse in i get an error saying the device may not be installed properly. When checking in the control pannel all devices appear to be fine but the port the mouse is in shows as 'unknown device' it seems to have suddenly lost the ability to recognise when something is a mouse
