Fresh install of Ubuntu 14.04.1 LTS (updates bring it up to 14.04.2 LTS)
USB 3.0 flash drive (Corsair 64 GB Survivor Stealth and Silicon Power 64G M70); both show slowness prior to loading "libccid".
OS: Ubuntu 14.04.1 LTS updated to Ubuntu 14.04.2 LTS
Plugging USB flash drive directly into the notebook computer (USB 3.0 port; not using HUB; ALL USB 3.0 external hard drives always connect at SuperSpeed).
Trying with two USB 3.0 ports (both are USB 3.0) and work fine in Windows as well as Linux (with external USB 3.0 HDDs).
Ports are completely clean and free of dust as are the brand new
