Phoenix & 6105i connection problem

Hello everyone! I've been trying to connect my 6015i to Phoenix (version 2006.20.9.148) but it would not recognize the phone. When scanning all the available connections, it finds something on USB but it fails to connect when I click "Phone Information" (same thing happens even when the phone is not attached to the computer - no idea why it still recognizes an USB connection). I use a DKU-5 cable that initially was recognized as TUSB3410 - I installed the usb-to-serial port drivers (from texas instruments) and the DKU-5 drivers from Nokia (both after instralling Phoenix). So my questions are:

Anyone managed to connect 6015i to Phoenix, and if so, how?

Do I need a different cable, either a "normal" DKU-5 or maybe something else? What have you guys used who managed to connect any Nokia to Phoenix?

In Phoenix, what is the difference between USB and DKU-5 connection? Isn't the DKU-5 an USB cable??

Thanks a bunch! You can reply here or PM me.
