It seems that I have a bad USB cable. It worked on USB 2.0 but the
extra wires for USB 3.0 were intermittent. After replacing the cable I
am running on a 3.13.0-53-generic kerel which it never could before.
When I changed the timeout, and it ran good, I must have had a good
connection on the cable. I did see some ports stop working though,
because they were messed up by that bad cable.

Yes, this fixed the problem. Thanks for your help.
That doesn't mean exactly that this change fixes your problem.
I would suggest you to try the latest kernel without any changes
to check whether the fix is already there. Then you can go ahead
with changing the timeout value to check whether it helps.
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.
The USB 3.0 port non-working issue might be due to CEC error
not cleared. Again, I would suggest you to check with the latest
kernel version. If the port non-working issue still exists, you can
report a bug in the bugzilla and forward that to this mailing list
somebody will assume the responsibility to get it fixed.
