Does this mean that the touch screen is hitting a limit in FreeBSD's

Yes, the hid driver is limiting the range of some report. This should
be harmless. You would need to dump the HID descriptor to see the
limits. Maybe we could raise the limit from 256 to 4096 or something
in that range, to make the warning to away. It's
sys/dev/usb/usb_hid.c:
/* range check usage count */
if (c->loc.count > 255) {
DPRINTFN(0, "Number
of "
"items truncated
to 255\n");
s->ncount = 255;
} else
s->ncount =
c->loc.count;
Try adding c->loc.count to the printout, to see the limit it is
exceeding.
--HPS
hid_get_item: Number of items truncated to 255 (was 256)
Any chance of someone(tm) committing this small patch to add this info
by
default?
