Hi all,

After I installed driver for my Toshiba e330, it worked fine for a couple of days, then suddenly my PDA told me couldn't find the GPS unit. I used GPS viewer to check, found out COM1 failed to open. I reinstalled the driver on PDA, it started working again. From then on, this problem is happening everyday and I tried reset my PDA, disable infrared ports on PDA, still not help at all. I sincerely hope you can give me some good suggestions to fix this problem.
