There's a lot of reviews from Windows users saying this drive hangs if connected to a USB 2.0 port, however I see you have it connected to a USB 3.0 port (xhci_hcd).
The other issue could be that you are using an unpowered hub, or plugging it into a regular USB 3.0 port (900mA) instead of a dedicated charging port (1500mA) which many drives require.
Is the port colour yellow? Does it feature a lightning bolt silkscreened above it? Can you rapid-charge a compatible phone from that port?
