USB 3.0 external HDD does not work

[Lars Engels]

I just bought a shiny new external 2.5" USB 3.0 HDD (Samsung Portable 3.0).
However on my notebook with USB 2.0 it does not work. dmesg output after
inserting it:

usb_alloc_device: set address 2 failed (USB_ERR_STALLED, ignored)
usbd_setup_device_desc: getting device descriptor at addr 2 failed, USB_ERR_STALLED
usbd_req_re_enumerate: addr=2, set address failed! (USB_ERR_STALLED, ignored)

The notebook is running CURRENT (r220370).
I also tried all other USB ports, all don't work.
