The good news is that I've just completed running the "usbtest"
suite on the 2.5.44 UHCI, and it didn't hang for me after even
a hundred full test runs! That's a big improvement; previously
it deadlocked during my first or second run.
I also tested full speed behavior on OHCI and on EHCI (using a
USB 2.0 hub and transaction translator, plus that patch I sent
recently), getting the same basic success. (*)
The bad news is that now we'll have to add more test cases, and
start getting to more things we suspect may not work right!

(*) So it should be a good time for usb-storage to start using
those usb_sg_*() calls in development patches.
