with the patch, netbsd-10 boot messages changes:
-ehci0: pre-2.0 USB rev, device ignored
+ehci0: unknown USB rev: 0x00000000
+ehci0: EHCI version 1.0
+ehci0: Using DMA subregion for control data structures
+usb0 at ehci0: USB revision 2.0
Ignoring the cascading "X is now +1 for every usbX message" the other change was
+uhub4 at usb0: NetBSD (0x0000) EHCI root hub (0x0000), class 9/0, rev
2.00/1.00, addr 1
+uhub4: 1 port with 1 removable, self powered
