Google finds some references to what appear to be two different
problems with ehci in 3.8. Those might be fixed in 3.8.2, but I'm
not sure and in any case I'm not convinced they are exactly the same
as your problem (one at least seems to be due to not putting all the
modules in an initrd).
What I do notice is that ehci has been split into ehci-hcd,
ehci-pci, ehci-platform in 3.8. OTOH, my own .config for 3.8.2 only
appears to know about _HCD and _PCI so that might very well be a red
I'm hoping that you identified the correct usb modules from what
the host distro is loading ?
I *really* think you will need to build an older kernel as Bruce
suggested, to get to the bottom of this. If it's an unfixed
problem (which might be specific to your hardware) you might even
need to use git bisect to find out what broke it. 3.7.10 is already
EOL'd according to www.kernel.org, so I would be inclined to try
starting from 3.7 itself - just to get a kernel which boots ok (it's
possible that 3.7.10 will also be broken for your hardware, because
a change in 3.8 has been backported).
Once you have 3.7 booting ok, try 'make oldconfig' for 3.8.2. You
can save your current 3.8.2 .config before that, and then diff them
to see if anything in the usb area changed. If nothing _did_ change,
it looks like you are in for fun and games to fix it. Hopefully,
something did change and you will now get a usable kernel. Good
