[maemo-developers] [maemo-developers] Getting the pl2303 usb serial driver to work with /dev/ttyUSB0

[From: Ed Bartosh]

Hi,

PL2303 driver is compiled into n770 kernel:
grep ^CONFIG_USB_SERIAL arch/arm/configs/n770_defconfig
CONFIG_USB_SERIAL=y
CONFIG_USB_SERIAL_CONSOLE=y
CONFIG_USB_SERIAL_PL2303=y
 
My pl2303-compatible usb-2-serial adapter works with n770 without any modifications.
Unfortunately I don't remember the model. I'll tell you tomorrow if it's needed.

And you probably don't need to makedev devices. udev should take care of them.
inittab should also be modified to run getty on ttyUSB0 if usb2serial device is 
connected to n770 on boot stage. 
Look at /etc/init.d/ttyusb for the details.
