Hello.  I never run scsictl to probe a newly added USB device.  When
it's plugged in, if all's well, it's probed and all targets are attached.
	Below is an excerpt from cvsweb.netbsd.org showing when the changes
from usb_subr.c V1.130 were pulled into the netbsd-2 and netbsd-3 branches,
respectively.  It looks like the netbsd-2-0 branch was left in the cold, so
if you want this new functionality, you need to go with NetBSD-2.1,
NetBSD-3.x or NetBSD-current.  Or, just apply the patch manually, which is
what I did for a couple of months before I upgraded everything to
NetBSD-3.0.

        sys/dev/usb/usb_subr.c: revision 1.130
usbd_setup_pipe(): Don't call usbd_clear_endpoint_stall(). It's not
necessary for normal devices, and it prevents some common (but
apparantly buggy) devices from working, including the Apple iPod (mini
and photo) and certain M-Systems DiskOnKey flash devices.
If (also buggy) devices resurface that need this when they are
attached, they can be addressed, ideally in each device's driver.
