QCC5125 change device name via QCC_Tool or other s/w via USB

Hi,
in this thread some users managed to connect to their QCC5xxx bluetooth modules via USB to change settings. I tried it with the provided QCC_Tool_v1.0.3.exe but the tool does not recognize my QCC5125 module. Do I need particular Windows drivers for the debugging USB interface?
If so: May s.b. please provide them or assist me? I just want to change the device name.

The Windows device manager shows three devices if i connect the QCC5125 via USB to the PC:
  • Audio devices > QCC5125
  • USB controller > Generic USB hub (HW ID USB\VID_0A12&PID_4010&REV_1669)
  • USB controller > USB device (HW ID USB\VID_0A12&PID_4007&REV_1970)

Thank you very much for any hints!
