USB 2.0 Ports
When installing XPpro in my Dell4600, I encountred problem in the USB ports.
When cable was plugged into port1 USB View software can identify it as high speed, how come when cable was plugged into Port3 it says " NO DEVICE CONNECTED"? Is there a separate driver in every ports? |

USB 2.0 Ports
Check in the device manager to see if there are any
conflicts or even to see if they show up. On the desktop, right click on My Computer, go down to properties, click on Hardware, then device manager. Look for Universal Serial Bus Connectors, should be a the bottom. Click on the plus, are there any yellow exclamation marks? If not, then thats good. If there are, then you have conflicts. There should be a Host Controller for each port as well as a USB Root Hub for each. Mine shows two Host Controllers and two USB Root Hubs since I have only two USB ports. It sounds like you have four or six USB ports? You should show four/six controllers and four/six Root Hubs. It almost sounds like they aren't physically connected. All four of the USB ports on on the back? Or are there two in the front? Did you have this problem BEFORE the install? -----Original Message----- When installing XPpro in my Dell4600, I encountred problem in the USB ports.
