CC2540 USB Dongle not work with BTool 1.3

Dear,

I had CC2540EMK-USB and installed BTool 1.3 on my PC, WinXP. My PC already installed Microsoft .NET 3.5 SP1. USB driver is automatic install (Cebal controlled device -> CC2540 USB dongle).

When I start BTool, it cannot find the right COM port to talk with the dongle.

Then I follow the swru270b.pdf and found NO additional COM ports create by BTool (Figure 9 on the user guide) and I cannot update the USB driver manaually.

Does it problem on BTool V1.3?

Please advise, thanks
