Looking at the debug output it looks like there is a device when the kernel
tries to retrieve the first 8 bytes of the device descriptor.  This is the very
first thing that happens, so it's hard to say how to fix it.  There are some
timing constants in usb.h that you might want to fiddle with, but it's doubtful
if it will work.
