USB HD not recognized in CuBox i4 Pro

Hi,

I have Volumio monted on UDOO which works fine (excluding NAS but this does not matter); yesterday I received my new CuBox i4 Pro, well it works fine in RamPlay and Web Radio but it does not recognize my USB self powered HD. It simply does not exist. On Udoo it works quite well so it is not an HD issue and also it is not an issue of USB ports because I switched USB Dac and HD and again DAC was working andHD just light on but no files listed in Volumio.
I only use cable connection to the LAN because I read there were bugs in setting up the WiFi (again on Udoo it works fine).
Does anyone else experienced the same issue? Some solution?

Best

Raffaello
