Cannot connect to pdanet using a usb cat5 extender

[AC Question]

I wanted to connect my phone from farther away, so I purchased a usb cat5 extender. I know it is working, because I can connect a hard drive and it works fine. Pdanet desktop see's the phone, but when I try to connect, it says connecting to your phone (usb)... and just sits there and never connects. Any suggestion on what is wrong or how to troubleshoot? This is a 50' cable, but I also tried a short cable and it does the same thing.
