The problem with the cy driver resides in the function cyattach_common in the cy.c file. make_dev is called like this: make_dev(&sio_cdevsw, unit, UID_ROOT, GID_WHEEL , 0600, "ttyc%r%r", adapter, unit % CY_MAX_PORTS); where 'unit' is 0 to 31 for board one 32 to 63 for board two 64 to 95 for board three 96 to 127 for board four. But when I use 'MAKEDEV cuacX' for the installed and configured cy devices, MAKEDEV does the following: minor='ttyminor $unit' minor='expr $card \* 65536 + $minor' The second argument in make_dev function needs a conversion something like : make_dev(&sio_cdevsw, ( adapter * 65536 + ( unit % CY_MAX_PORTS ) ), UID_ROOT, GID_WHEEL , 0600, "ttyc%r%r", adapter, unit %CY_MAX_PORTS); 2.) For some reason there is sometimes a problem with detecting the CD1400 ic's firmware_revision. I solved it by increasing the DELAY values in a loop and inserted some (extra) loops and check's, but I don't know whether or not it might hurt at some point?
