Can't find tty-usbserial-XXX under Yosemite 10.10.4

Hi, guys

After I plugin my lilypad main board on Yosemite 10.10.4, and open the latest version of Arduino IDE(1.6.5), the tty-usbserial-XXX serial port cannot be found, there are only ports like cu-XXXX.

But I can see these entries in /dev directory:
/dev/cu.usbserial-AI02TT3P
/dev/tty.usbserial-AI02TT3P

Anyone can help me? Thanks a lot.

The latest IDE only shows the cu.usbserial ports which seems to act identically to the tty.usbserial version. Just use the 'cu' version.

Thanks for your reply.
