OK, thanks.  Looks like it isn't really in the kernel.  I made a build
with adding "device ehci" and I think "pci/ehci" is the actual device,
not "ehci/usb".  Sorry for the noise.

FWIW, using ehci doesn't cause me any additional issues with USB.  My
umass pen drive behaves the same with/without ehci except it is faster. 
This makes me think that my previous issues are with the msdos
filesystem, not the usb driver.

Cheers,
Sean
