USB device disconnect suddenly

Hi,

I am now using P3 computer, it seems my USB port got problem.

i have tried to use USB mouse before. But it disconnect after using for a while. What i have to do is unplug the usb mouse and then wait a while, replug it again.

besides, i tired to use a wireless USB lan card...just the same situation, after using for a while, need to unplug and plug again to make it works again.

Anyone can tell me what's wrong with it?
Thanks a lot

>>Anyone can tell me what's wrong with it?
its so hard to tell with usb has it has many problems.  One thing that I can think of is lack of power for the device.  How many devices do you have hooked up to the USB ports at once?   A power problem could be solved by a powered hub.

Ha!  I see buckeyes33 has latched on to my USB link - I knew it would catch on.

cnfei, your USB controller may be powering down to save energy.  There is a checkbox in the properties panel for the USB hub in device manager that you might want to look at.

what can i do if really lack of power?

when i am downloading a number of things. I just can use winamp to listen to songs...cause the song playing is not stable...start and stop. it is because of the usb wireless lan card i think. Cause i don't have this problem when i am use lan cable.

Take any other USB devices off and see if that makes a difference.  Otherwise, you may need a powered USB hub, as buckeyes33 says.

Wireless is limited to 11Mbits/sec for 802.11b, 54Mbits/sec for 802.11g, and cat5 wired is limited to 10 or 100Mbits/sec (more likely 100 with today's cards).

But i only have one USB device, which is USB Wireless lan card.

So what you mean is buy a powered USB hub to make it stable?

Callandor, even I uncheck the checkbox in the properties panel for the USB hub in device manager, the USB wireless lan card still disconnect itself, and i need to unplug it, and wait for about 20 seconds to plug it again to make it works.

that makes it sound even more like a power issue, but with only one device on it????   Strange, i think I might have to think about it a little more.

Actually, I have a USB webcam that behaves this way too.  After I unplug it and replug it, usually a few times, it is recognized.  Not all devices on the same port behave this way, for example, pen drives work all the time.  It may boil down to the particular device.

I had a controller that once did this with ME, when it happened the computer would stutter and then controller would be useless untill put back in.  After a while of this happening I decided to plug it into a USB port in the back and it worked fine after that.  Turned out the ports in the front of the computer were not much good.  So maybe changing ports with it if you are using a port other then something directly into the motherboard.

My USB WebCam, USB Optioncal Mouse and USB network card all act like this, needs to unplug and replug to make it works again...

Now i didn't use the webcam and USB Mouse already, so only USB lan card left.

I have tried to use different USB port, just the same thing happened.

This is probably just one of those wierd USB problems.  You are not the only one that has these problems.  USB is not a prefect science and who knows when it will be.  The only suggestion I can give you is try a powered hub.  Otherwise I am really at a lose as it happens with all your USB items it has to be hardware related.

i have tried...

and after installed USB2.0...my usb wireless lan card doesn't work at all.

CallandorCommented:
You can remove it in device manager, and run SFC /scannow to get back the original drivers.  Did you try a powered USB hub, which buckeyes33 suggested?

cnfeiAuthor Commented:
yes..

i did try...but still cant solve the problem

CallandorCommented:
I can only say that your motherboard is not providing stable USB support.  I have seen the same device not work too well in one motherboard, but work all the time in another.

I have an Abit KT7-RAID in one of my machines - nice and stable, with a 1.2GHz T-bird.

The more recent motherboards seem to do a better job of handling USB.
