I have both a Western Digital MyPassport Essential 500GB harddisk and a Seagate FreeAgent GoFlex Desk 2TB working ok on my ASUS U3S6 XHCI controller in USB 3.0 mode. Currently I'm using ubuntu 10.04 (Lucid).

When I disconnect the devices, and connect a USB 3.0 hub (DeLock USB 3.0 External HUB 4 Port), the HUB is detected by linux, but no USB 3.0 devices (i.e. the mentioned HDDs) connected to said HUB. USB 2.0 devices connected to the HUB are detected and working properly, though. When connecting the hub, 2109:0810 and 2109:3431 appear in "lsusb".

I've got the HUB working in 3.0 mode by means of compiling a kernel from git: dbe79bbe9dcb22cb3651c46f18943477141ca452 (USB 3.0 Hub Changes). I'm not 100% sure if this is the exact commit enabling USB 3.0 HUB operation, but there is strong evidence for it. If this is "the fix", the next ubuntu release (11.10) will likely support USB 3.0 HUBs "out of the box".

In addition to 10.04, I also tried the HUB on 11.04 (natty), observing the same problem. For now I'll omit the "default" system information, because I believe the problem is not related to my particular hardware setup. If you request, I'm happy to submit this information too.
