I have a few problems re. USB and hope if someone could be able to help.
I'm running XP SP2 with the latest updates installed. The motherboard is ASUS P4B533E. It comes with 3 USB hubs (6 ports altogether). On one of the ports I've plugged in an USB Microsoft Internet Keyboard Pro. Sometimes when I plug in an USB device (like an external USB harddrive, on a different port on the motherboard, that is not on the ports with my USB keyboard) it will disconnect on its own (you can hear that sound Windows does when an USB device is plugged and unplugged) for no particular reason and then very soon afterwards (about 4 or so seconds) it will reconnect itself again. Sometimes this will keep on happening if I maintain the USB device to be plugged on the port until a balloon pops up on the system tray saying the data transfer speed of the USB device has to be dropped to USB 1.1. The problem with this is if I want to do a harddrive backup and it disconnects itself in the middle of the process it is very annoying. Recently I've also bought a Dlink DWL-G122 USB Wifi adapter and this connecting/disconnecting problem reappeared and I'm unable to maintain a reliable internet connection. I've tried reinstalling drivers (about a million times) and unchecking the box under the power management tab in the USB settings in device manager. I suspect that this problem is to do with my USB hubs on the motherboard unable to maintain a steady power supply. Does anyone have any idea as to why this happens, please??
I've heard from a friend that a PCI to USB card often works better and is more reliable. Any substance to this claim?
