Which Windows version are you running with?
If it is Windows XP, follow this instruction:
If you use MS Windows XP, some difficulties can arise with p2k driver installation. After installing all drivers, there will be just non-working "USB composite device".
§ You should run the Registry editor (Start->Run…->regedit->OK).
§ Then you should find key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\U
SB\Vid_22b8&Pid_3801\ or something like that.
§ Right-click on key Vid_22b8&Pid_3801 -> "Permissions...", than set Allow "Full control" for user EVERYONE.
§ There is a key inside the key Vid_22b8&Pid_3801 (in this example, it's 5&28da0f34&0&1). You should open it. Find there string "Service", with value "usbccgp". You should change it to "usbhub".
§ Then you should open the subkey "Control". Change there string "ActiveService" value from "usbccgp" to "usbhub".
§ Then delete all key, starting with "Vid_22b8&Pid_3801&MI_xx", where xx is some number. (OF COURSE DON'T DELETE THE KEY, THAT YOU'VE CHANGED!!!)
§ Now you have to disconnect the phone for 5 seconds, then connect it. System should find all the devices again, and you should choose the same driver.
§ Then open P2kMan, wait something about 2 minutes (until Phone status would change to "connected"), then press "Update file list". List of files should appear.
Sometimes you have to reboot your PC.
