Well,
I tested this patch and it does nothing for UHCI :-( It might work  
great for OHCI but someone else will need to test it.

So I tried a low speed device (old usb mouse) and it did something  
different, it still errored out of course (because it is not a drive)  
but I think it was working the way it is supposed to??? Anyways I also  
tried a USB 2.0 flash drive with no success. I think what is happening  
here is, it is not falling back to low speed UHCI......see  
attachment....I don't know where to go from here....

Thanks - Joe
