5.2-BETA USB woes

The full tale of woe can be found at:

The executive summary is that after some unfortunate hardware failures, 
I picked up an ASUS A7V8X-X motherboard with a 6 USB 2.0 ports.

GENERIC doesn't appear to have ehci in it, so not a great deal 
happened.  I then took the GENERIC kernel, ripped out all of the USB 
code from the kernel and enabled usbd(8) to hopefully do the right 
thing.

There's a single USB device connected up (an MS optical cordless 
wheelmouse, which works just fine with XP and Gentoo Linux, and is seen 
by 4.9-RELEASE, though nothing much happens with moused).

Here's what happened:

No mouse detected, usbd is running, but all the ports are dead.  
Disconnecting and reconnecting the mouse has absolutely no effect 
whatsoever.

If a friendly USB guru happens to be around, I can provide ssh and root 
access to the box, or if there are further diagnostics I can run, 
please let me know.
