>Description:
Some recent commit of sys/dev/usb/ohci* apparently broke it for sparc64.
/*	$NetBSD: ohci.c,v 1.155 2005/02/27 00:27:51 perry Exp $	*/
works fine, but 
/*	$NetBSD: ohci.c,v 1.157 2005/03/11 19:25:22 mycroft Exp $	*/
hangs after finding the root hub:

ohci0 at pci2 dev 1 function 0: CMD Technology USB0673 (rev. 0x05)
ohci0: interrupting at ivec 10
ohci0: OHCI version 1.0, legacy support
usb0 at ohci0: USB revision 1.0
uhub0 at usb0
uhub0: CMD Technology OHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub0: 2 ports with 2 removable, self powered
... here it would hang ...
uhub1 at uhub0 port 1
uhub1: vendor 0x03eb Standard USB Hub, class 9/0, rev 1.10/3.00, addr 2
uhub1: 4 ports with 4 removable, self powered
uhidev0 at uhub0 port 2 configuration 1 interface 0
uhidev0: Logitech USB-PS/2 Optical Mouse, rev 2.00/20.00, addr 3, iclass 3/1

the same code works fine on macppc though.
>How-To-Repeat:
put an ohci card into a sparc64 box, reboot.
>Fix:
downgrade to an earlier ohci driver
