Tim: This has nothing to do with USB-3. You can tell from the log:
> Dec 6 13:33:29 twpsamlinux kernel: [ 512.148960] usb 3-1: new full-speed USB device number 2 using ohci-pci
OHCI is strictly USB-1.1. However, you have not provided nearly enough useful information to tell what's going wrong. You didn't even say what version of the kernel you are using! -- let alone provide a usbmon trace like some of the other people contributing to this bug report.
