1.) 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?

I have two cyclom YeP PCI board installed with 32 serials ports
connected to both on a FreeBSD 4.0 release system.
The first board (cy0) is working without problems however the
second one (cy1) give some trouble.
When I try to connect to a port e.g. cuac10 - cuac1v a kernel
warning is displayed:
'WARNING: driver cy should register devices with make_dev ()
(dev_t = "cy/0x1008f")' but the connected is made.
I added some 'printf ()'s to the 'cy.c' file in the
'cyattach_common ()' to verify whether 'make_dev ()' is called
for the relevant ports and that seems to be OK. So my question is
what wrong here? Can someone give a hint?
