The USB ports of Compaq5 1 1 xp system all don't work. A series of exclamation point driver wizards in Device Manager show that the USB driver is damaged, but it cannot be installed.

Hello, thank you for choosing HP products. You are advised to refer to the following information:

The problem you mentioned is probably caused by a problem with the USB driver of the machine. I suggest that you can solve the problem in the following ways:

1. It is suggested that you right-click Computer-Management-Device Manager, find a universal serial bus controller, uninstall all drivers of USB root hub and devices with exclamation marks under it, then right-click any device and select "Scan for hardware changes" to reinstall USB drivers.

2. If the problem still exists after reinstalling the USB driver, it may be caused by a system problem. I suggest you try to save important files and reinstall the operating system to see if you can solve the problems you encounter.

I hope the above reply can help you.
