The trace shows that something is sending an invalid INQUIRY command (one with a 512-byte transfer length) to the drive. Normally such things are done by user programs, but in this case it looks more like the command came from somewhere in the kernel. I have no idea where. Did you change anything besides the kernel when going from 3.10.2 to 3.10.3? If you boot now into a 3.10.2 kernel, does the drive work? What happens if you plug the drive into a USB-2 port? (I expect it will make no difference at all.)
