did you download all available updates from Microsoft at microsoft.com?
If not do so. another thing you can try, do any of the usb ports work with any other devices? if they do, then something is broken that your trying to make work. if none of the usb ports are working......
1.) visit Microsoft update as described above, however click custom when the page loads and install all hardware updates.
2.) if it still don't work, visit your website for your brand of computer, and click support on there page and type the problem your experiencing and see if they have a fix available.
3.) try right clicking my computer-properties-hardware tab-device manager-right click one of the usb main controllers, and click properties. then click driver-update driver. follow the wizard and have it search everything possible. install what is given.
try those solutions, if none work, contact your computer provider.
First of all: I have an old Compaq Presario 5360 with Sis 7001 PCI to USB controller. This machine was working GOOD, I could work with my USB web cam, USB drive, USB digicam and others MP3 players.
I have reinstalled my WinXP with Service Pack 2.0 and now I CAN'T use any USB device, when I connect my USB drive this device is not powered, XP doesn't notify me for anything... simply this PC looks not to have any USB controller.
I have an DELL Notebook, I can use my USB devices on it.
I just reinstalled the OS in the same way how I did it before.
I think is something about drivers, the control panel (System devices) tells me everything is good and my USB controllers are working correctly.
I need your help
