Hi, I have a USB 3.0 Disk 2TB (WD Elements).
When I plug in a 2.0 USB Port the disk is recognized, but when I plug in a 3.0 USB Port the disk is not recognized and the dmesg not show anything. This is the exit of command "sudo lsusb": Bus 002 Device 002: ID 8087:8000 Intel Corp. Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 002: ID 8087:8008 Intel Corp.
