Removing USB-1616FS boards from Windows XP systems
Device Manager may require up to 30 seconds to detect the removal of a USB-1616FS board from a Windows
XP system with Service Pack 1 or Service Pack 2 installed. This time increases with each additional connected
board. If you remove four boards from your system, the time required for Device Manager to update may be
almost two minutes.
If you re-attach the USB-1616FS to your system before Device Manager updates, the USB LED will not turn
on. Your system will not detect new hardware until Device Manager first detects that hardware has been
removed. The InstaCal software will be unresponsive during this re-detection time. Wait until Device Manager
updates with the new hardware before running InstaCal. The USB-1616FS is detected by the system when the
device LED is on.
