hello,
Current /usr/sbin/usbdevs handles up to 10 USB host controllers.
But my PC has 11 hosts, here is the result of dmesg | grep usb.

There is only way using "usbctl -f /dev/usb10" (from ports/sysutils/usbutil)
to obtain the information for devices that attached 11th host.
NetBSD's usbdevs uses /dev/drvctl to break the limit, or up to 16 hosts.
We do not have /dev/drvctl, so we have to simply increasing the value.
How much is the suitable? I am trying with 24 (32 is too much I think),
is there any good ideas?
And, at least we also have to fix ports/sysutils/usbutil and
devel/libusb-1.0 (libusb-compat not checked yet).
