>Description:
The Cylcom YeP device driver has a problem with registering the devices for the second and futher boards
Either the MAKEDEV script or the syscalls to 'make_dev (..)' in cy.c should be changed.
>How-To-Repeat:
Just install more than one YeP board and rebuild a kernel supporting both board. Try to connect to a port on the second board.
example : cu -l /dev/cuac10
>Fix:
the second arg in make_dev should be something like this :
( adapter * 65536 + ( unit % CY_MAX_PORTS ) )
