>Description:
puc(4) is a Universal driver for serial & parallel ports. It supports
variaous chips & boards except the one I bought from market, SUnix's
daul ports parallel card with SUN1888 chip.
>How-To-Repeat:
Plug a parallel port card with SUN1888 to your FreeBSD box and try to
drive it with puc driver module. Nothing is happening.
puc(4) can not even recoganize the card.
>Fix:
apply following small patch on src/sys/dev/puc/, and rebuild the
module in src/sys/modules/puc/.
