I have a compaq presario computer 4100CA, RUNNING windows me.
The USB is not working
Info on USB ... intel (R) 82801AA
If I click on device MANAGER I am promted with (this device is working properly)

I would like to know if I need a driver, what driver I need and where can I get it?
TIAWhat device is not working (just one usb device or all devices)? Have you tried different usb ports?I have tried the two ports many times. both of them will not work.
Everything else is working ok.
On device manager, I click on three usb ROOT hub ,host controler etc. I always get (this device is workin properly)Again, is it one usb device that is not working or do no usb devices work? And did the usb ports ever work?No USB ever worked.
This computer was GIVEN to me. I have reloaded it from scratch on a formated hard drive several times.
If there was something wrong with the motherboard, I don`t think I would be prompted with (this device is working properly)
Is it possible that I need a driver for it?You should have said it was a new install right off the bat. You need to install the chipset driver.The USB did not work when I got the computer, even before I started it from scratch. It still will not work when I install the original hard drive. Every thing else seems to work OK.
I have another compaq computer model 5WV257 and I have reloaded it from scratch too, and it is running OK even the USB.
This is a hobby for me.
If I need a chipset driver, I would like to know what it is, and where can I gat it.

Thank you very much.The chipset driver should have been provided on a cd with the computer. Otherwise go to the website of the chipset manufacturer or here: http://www.nodevice.com/driver/category/Chipset.html

It should be the FIRST driver installed after the OS is installed.HP Customer Care
