Running debian sarge. I added a Siig Inc CyberSerial (2-port) 16650 pci card. When I look for the new ports:
debian:/dev# dmesg |grep tty
ttyS00 at 0x03f8 (irq = 4) is a 16550A
ttyS04 at port 0xd800 (irq = 11) is a ST16650V2
ttyS05 at port 0xd400 (irq = 11) is a ST16650V2
I can see them as ttyS04 and ttyS05. These ports do not show up in the /dev directory.
debian:/dev# ./MAKEDEV ttyS04
./MAKEDEV: don't know how to make device "ttyS04"
