CPU usage goes up when connecting USB device to Dell Latitude E6530 USB 3.0 port
Hi.
I have the same problem on a Dell Latitude E6530 from this post : en.community.dell.com/.../20013042
(I cannot answer in the original post, the forum gives me an error).
I use Windows 10 Pro 64 bits (1703).
The BIOS is up to date : version A20 (05/08/2017).
When I plug ou unplug a device on the USB 3.0 ports (right or left port), the System process goes up to ~15% CPU usage. I have to sleep/resume or reboot to have a normal CPU usage.
The CPU usage is taken by the ACPI.sys (found with Windows Performance Recorder).
This problem does not happen with USB 2.0 (rear port) or E-SATA port on right.
What can I do ?
