What brand CAT6 cable do you prefer and have you had bad experiences with any? Networking.I'm hoping there are setting changes to resolve this since the ports themselves are fine and it's just 2.0 that appears not to be working. Tried pulling battery and power adapter for a couple of minutes, no change. I found a registry hack to try called DisableSelectiveSuspend, no change. Powered USB hub works fine too when the enhanced PCI to USB hub is disabled. Of course, I get an instant message in the tray telling me that 'this device can perform faster' and I should plug it into a USB 2.0 port. Then I deleted the enhanced PCI to USB host controller but left everything else, and now my digital camcorder is recognized. Tried the same thing with a reboot, again, no joy. So, I have tried deleting all the USB devices from device manager, and letting them be re-detected. When I unplug the powered USB hub, it unfreezes and continues as if nothing was ever wrong! If I connect a powered USB 2.0 hub, the computer freezes. In this case, my digital camcorder is what is not being recognized. I connect a usb 2.0 device, and the system tray tells me the device is not recognized. I connect a usb 1.1 device and it is immediately recognized. 1 GB RAM, AMD Turion 64 processor (yeah, I am a cheapskate on my personal computers.) This is fully patched WinXP Pro, with the latest firmware, chipset drivers, etc.

Just now, the USB ports have quit working. I have had it working great about a year for the light-duty stuff I do at home. My personal laptop is this Acer Aspire 5100 that a friend gave me.
