Are there any known problems with Windows XP SP1 and USB I/O devices?
Yes, the USB driver built into Windows XP SP1 (Service Pack 1) has issues with suspend, hibernation, and restarting. This issue potentially affects all USB devices and is not specific to those manufactured by Sealevel Systems. Microsoft released Hotfix 822603 to address this problem. If you are running Windows XP SP1, visit this linkfor information on how to download and install the patch. If you are running Windows XP SP2 (Service Pack 2) or greater, you are already using the updated driver and do not need to apply the patch. If you are having other problems with a Sealevel device, please contact Technical Support.
