Hi Don W,
thank you very much, I uninstalled the old one and installed the new one version 1.0, but unfortunatelly it doesn't change anything. I can see in DeviceManager the libusb (WinUSB) devices -> Ettus Research LLC USRP1 (VID=FFFE; PID=0002; REV=0004). If I run uhd_find_devices.exe the result is the same as before, no error, from ...\UHD\bin>uhd_find_devices.exe comes back to ...\UHD\bin>, so it's a situation of everything is installed but nothing works. Anyway thank you very much for the information.
Have a nice day.

Devices -> USRP filter (VID=FFFE; PID=0004
Isn't LibUSB-Win32 the old libusb 0.1 driver? What happens if you uninstall the driver in the device manager and reinstall with the libusb 1.0 driver?
