Comment 41 for bug 627022

I also reported a pretty much duplicate issue with this in #836349 ... looks like this has been ongoing for a while and is stuck on kernel API call changes... I was trying to upgrade to Ubuntu's kernel 2.6.38-10 (really need 2.6.39 as that is known to have USB 3.0 **HUB** support 38-10 might have backported that but I don't know).. I guess the only way to go is to skip to something not LTS that might have a newer / new enough kernel. YES the current kernel I have has xHCI support, and my two hard drives plug in and work (fast) but can't add a third USB 3.0 drive without a USB 3.0 hub and that support isn't added until 2.6.39 . So for me now, it's have USB 3.0 Hub support for nVidia OpenGL (and dual display) support..
