Having trouble with USB connectivity?
An update for WindowsXP was just released that resolves an issue with USB device connectivity to USB 2.0 ports. In particular this can affect Pocket PCs if you power-cycle them while they're connected.
Here's the writeup from the KB article:
When you connect a Pocket PC handheld device to a USB 2.0 hub or turn off the device and then turn it back on while the device is still connected to the USB 2.0 hub, Windows may not redetect the device. This problem may also occur with other USB devices that have pending transfers if the device is disconnected and then reconnected, or if the device is turned off and then turned back on while it is still connected to the USB 2.0 hub. After you install this item, you may have to restart your computer.
