I currently have a Dell inspiron 7548 with windows 10 x64.
This laptop has 2x usb 3.0 ports and 1x usb 2.0.
Basically what is happening is that I cannot use any 3.0 usb external hdd on a usb 3 port. As soon as I insert any usb 3 device on a usb 3 port it starts connecting and reconnecting intermittently with windows plug and unplug sound also playing.
I tried setting all the power options for high performance...disabling usb selective suspend...disabling all the power saving capabilities on the device manager for each usb port, also tried disabling usb emulation and powershare from dell bios.
I don`t know what else to try.
Maybe someone here could know the answer to this problem. I will leave a video of my problem so it might be easier to identify:
