[A. Andria]

Hi all,

I can't find pl2303.h file on breezy.
I try to load the pl2303 module with modprobe pl2303 and it loaded.

My dmesg output show this :
root at asep-ubuntu:~# dmesg | grep usb

address 2

[4296078.405000] drivers/usb/serial/pl2303.c: Prolific PL2303 USB to 
serial adaptor driver v0.12

But i can't find the /dev/ttyUSB.
And how to make the pl2303 loaded automatically when PC rebooted?

Can you help me guys ?
