I have an AMD E-350 PC with this USB3 controller on the motherboard 03:00.0 USB controller: NEC Corporation uPD720200 USB 3.0 Host Controller (rev 04) I also have a Sans Digital TR4U+B 4-disk enclosure that I'm attempting to connect to the USB3 ports. Running Ubuntu 12.04.2 with kernel 3.5.0-27-generic things work fine. I'm trying to upgrade to Ubuntu 13.04, which by default has kernel 3.8.0-19-generic. With this kernel I get a "Timeout while waiting for address device command" when I plug in the Sans Digital device, and no drives are detected. I'm not using any sort of USB hub - I'm plugging the device directly into the onboard USB 3 port. Thinking perhaps this is a bug in 3.8 or in Ubuntu's version of it, I installed a vanilla 3.9 kernel. With this kernel I also get the same behavior as with 3.8.0-19-generic. See below for output from dmesg. Is this a known issue? Is there more data I can gather to help resolve this?
