As the owner of both a system with more than 10 usb root devices and
a VAX, I support this change.

The system with more than 10 usb root devices is a PC with multiple
USB controller cards installed for the purpose of testing NetBSD USB
device drivers against different host controllers (UHCI/OHCI/EHCI/XHCI),
so I run into the limit every time I install a new NetBSD version to test.
