I am running Ubuntu 14 on two Dell 690 computers. On one machine, the USB card reader devices are always enumerated last which results in a the card reader showing up as /dev/sde-sdh. On the other machine sometimes the card reader shows up as sde-sdh and sometimes it shows as sda-sdd) Is there any way that I can force the 2nd machine to enumerate the USB devices after the hard drives just like the first machine? This problem is driving me a little nuts. I do NOT want to create symlinks for the card reader devices.
