I am pleased to report that by taking relatively drastic measures, the
USB 3 issues I have been experiencing with SL 6 have been solved.
Using kernel-2.6.38.6-26.rc1.fc15.src.rpm
I built and installed using rpmbuild and the SL 6 gcc 4.4 environment:
kernel-2.6.38.6-26.rc1.el6.x86_64.rpm
kernel-devel-2.6.38.6-26.rc1.el6.x86_64.rpm
Using these rpm files, the machine boots, the Nvidia
NVIDIA-Linux-x86_64-270.41.19.run file produces a kernel module for the
video card works under X11 (both Quadro FX 570 for video and Tesla C2070
for computation) ,
VirtualBox builds its modules and runs MS Win XP Pro, a USB 2 device (a
flash drive) with a MS file system is readable under MS Win XP, and the
USB 3 external harddrive is seen and automounts displaying the same file
system behavior seen under
kernel-2.6.38.6-26.rc1.fc15 within SL 6 as well as under OpenSUSE. When
the same USB 2 device is detached from VirtualBox, the filesystem
automounts under SL 6 on the Linux host size. Also, the fuse-ntfs
mounting of a MS NTFS filesystem works and the drive seems readable and
writeable. (Aside: my machine has a 160.0 GByte HP OEM harddrive in it
that had MS Win XP HP installed -- this is NOT the file/filesystem I use
for VirtualBox, but is mostly used as a test to verify that I have full
NTFS access if I were to need it.)
My next endeavor will be to find a production (not rc) version of the
above kernel and redo the process.
If anyone wants/needs these RPMs, please let me know. Is there a
reputable public site upon which one post such binary files for others
to use? I do not want to grant FTP access to my machine. In a pinch, I
should be able to post these to my personal web site at my university
and one could get access by that means. Be aware that I have not yet
extensively tested this kernel nor have I verified the stability of it
-- if the machine crashes/panics, I will report this to the SL list.

Thus, I conclude that the current and rolling SL 6 x86-64 kernels do not
properly support all common USB 3 external harddrives and control
interfaces. I have not tested any other USB devices.
I have found the production Fedora 15 kernel, posted under updates . I
had forgotten that Fedora is a perpetual beta distribution, and a (more
or less stable) kernel (not a rc) would be in updates. That said, I
have the following RPMs available:
kernel-2.6.38.8-32.el6.x86_64.rpm
kernel-devel-2.6.38.8-32.el6.x86_64.rpm
that seem fully to function (again, Nvidia latest
NVIDIA-Linux-x86_64-275.09.07.run and VirtualBox modules build and seem
to work). I will report any crashes/panics or other anomalies to the SL
list.
Does anyone have a possible date for when the production stock SL6
(RHEL6) kernel will be updated (backported) to provide the full USB 3
support of the 2.6.38 series?
