usb help !!!!

my usb just suddenly stopped working?...and im really starting to miss my digital camera and mp3 player haha...is there anyone out there that can help me...what happens is a plug something in..say in this case my lyra mp3 player it says usb connected then i get the unknown device error and nothing i do helps i have even reformatted the drive and re installed windows xp pro, even going into device manager and deleteding the usb drivers dont work and now the ones on my board dont even work at all??? any help would be greatly appreciated

 

Are there any errors or unknown devices etc in Device Manager?

Have you updated your motherboard/chipset drivers?

 

i dont have the mobo drivers and it says unknown device for anything i pulg in...thats the only error, i had got it to work fine......for about 10 mins that is then it's back to the way it was, do you think installing my chipset drivers would help that?...if so what chipset do i have(i have a dell precision workstation 420)

 

Yes, install your chipset drivers. Also, in the device manager under options or view (i forget) check show hidden devices, you should now see your camera and lyras drivers.

You can find your chipset drivers here:

thank you for the help well see if it works

 

well i found things to fix the other small things on here but no chipset drivers i have however found a bunch of ones on cd i got with my other dells but dont know which chipset i have?..i was thinking it was 810 but im not too sure

You have Intel 840 chipset. I would have thought Dell would have had drivers for their own motherboard, but I guess not.

 

haha well just between you and me they arent the best company for tech support and drivers haha talked to 2 technicians and they could not figure this out either....neither of them even mentioned chipset drivers

 

i downloaded and tried to install the chipset thing said my current os allredy supporst my chipset??...which is kinda kewl but my usb are still haveing seisures and i cant figure out for the life of my whjy it's happening because if i disable and then enable the device it works great till i unplug it?

 

When you remove the device, do you right click the remove hardware icon in the taskbar?

Also, when your usb camera isn't plugged in, do you see the driver in the device manager? What about when you select "show hidden devices"?

 

yeah most times i dont even have to right click to remove it cause i get the unknown device message, no there are no drivers in the hidden drivers for my camera or any other usb device ive installed....i even went as far as installing a pci usb card and even thats doing the same thing(if i disable my onboard usb and disable the card then enable the card it'l work for a short period of time)....is there any way this has something to do with my irq assignment or maybe it's just my board screwin up?
