Yes, this fixed the problem. Thanks for your help.
Here is the kernel version that I compiled:
Linux 4.1.0-rc2+ #2 SMP Mon May 25 10:58:36 CDT 2015 x86_64 x86_64
x86_64 GNU/Linux
On the non-working generic ubuntu kernel,the USB 3.0 ports that time out
became non-working. I could plug my other working USB 3.0 devices into
that port, and they would not come up. So maybe if there is a timeout,
you should consider resetting such a port on the chip. For a while I
thought that some of my usb 3.0 ports were bad.
