This is the second USB problem that we've heard dealing with this kernel.
There is a brand new bugfix kernel out today that said it deals with a USB bug.
"* USB devices would not be detected on a PowerEdge R805 system. USB devices
are now able to be detected on the aforementioned system with this update."
I'm wondering if it is more than the Poweredge systems having a problem.
I'm still rebuilding that kernel, but I will put it up into the testing area
when it's done so you can see if it helps or not.

Hello,
I found out that the usb 2.0 support is broken in kernel 2.6.9-78 (smp
version).
If I insert an usb stick I get this in /var/log/messages:
Aug 4 10:14:25 lxcip59 kernel: usb 1-7: new high speed USB device using

If I remove the kernel module "ehci_hcd". I can insert the stick, but it
is only "full speed" and not "high speed":

If I go back to kernel-smp-2.6.9-67.0.22.EL.i686.rpm the problem with
ehci_hcd is gone.
Best regards,
Andreas
