I guess this might not be fixable at all. Getting spin speed/SSD or not
is done with this command (see
http://comments.gmane.org/gmane.linux.kernel.bcache.devel/554):

$ sudo hdparm -I /dev/sda|grep Rot
	Nominal Media Rotation Rate: Solid State Device

This is my internal SSD hard drive. I tried with a rotational hard drive
attached with USB, but get no information about that. Same with a USB
memory stick. This leads me to believe that it is not possible to detect
if a USB connected drive is SSD or not, and the kernel assumes
rotational drive as default.

Title:
  Doesn't detect usb flash drive as SSD

Status in The Linux Kernel:
  New
Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I installed Ubuntu 9.10 on a 4G usb flash drive, performed updates as
  of 19 Dec 2009, and installed bootchart.

  The bootchart showed ureadahead as blocking the boot sequence while it
  did the readahead (Spinning drive style) instead of doing readahead in
  the background as I was expecting for a SSD.
