Sierra 598 "No Device Detected"


Sierra 598 "No Device Detected"

I have been using a Sierra 598 USB Broadband card for several months with no problem.  Recently the SmartView software would not detect the device.  I took it to a Sprint service center they said tested in and said it was bad.  They promptly replaced it with a new card.  I installed the software and device and I am getting the same results.  "No Device Detected".  I have installed in another XP laptop and it runs perfectly. Any suggestions?  I am about to go crazy!!!  Thank you!!!
