Some devices don't work on 3.0 USB port?

My laptop a HP DV6-1149wm has 2x 3.0 USB, and 2x 2.0 USB ports.

Some devices will work fine on both, like flash drives, but some other devices, like my iPod, and my Android phone will not work on my 3.0 ports. They just don't show up at all, lsusb shows nothing, nor syslog.

Any idea why it is device-specific? Or is there any way to force my 3.0 ports to act as 2.0 for the time being? I don't have any 3.0 devices.

You didn't say which version of Ubuntu you are using. USB 3.0 is problematic (buggy) in all versions prior to 12.04 in my personal experience.

Your best options may be to upgrade to 12.04 (or upgrade your kernel to at least 3.2).
