Okay, My goal it to get my arduino board talking to my 770 but I'm having a hell of a time trying to build this Virtual COM Port kernel module. Source is here if you are interested.

I think I've got scatchbox setup correctly and I've got the kernel headers installed. But when I try to build the kernel module I get this:
Code:
[sbox-SDK_ARMEL: ~/ftdi_sio.tar.gz_FILES] > KERNELDIR=/usr/src/rx-34-kernel-headers make 
gcc -Wall -D__KERNEL__ -DMODULE -I/usr/src/rx-34-kernel-headers/include -I/usr/src/linux-2.6.20-16-generic/drivers/usb/serial/ -O   -c -o ftdi_sio.o ftdi_sio.c

ftdi_sio.c:253:24: usb-serial.h: No such file or directory
There is a "usb-serial.c" in the kernel sources dir but no "usb-serial.h" in the kernel headers dir.
Any ideas on where to go next would be much appreciated.

I still haven't gotten the kernel modules to compile. I found a thread on the arduino forums about trying to make the arduino act as a human interface device (HID). Which would remove the need for the FTDI driver but it looks like that thread has died.

My last idea is to build something like this to act as a fake keyboard and put it in between the arduino and my 770. But I haven't had time to look into it further.

Did you read the blurb on the download page?:

Required for 2.4 kernels that require FT2232 support only. FT2232 support included in kernel 2.6.9 or greater. Developed by Bill Ryder. Instructions in ReadMe file.

All other devices included in kernel 2.4.20 or greater (see ReadMe for 232R device support).
Sounds like a kernel re-compile may produce a module that does what you want. From the instructions linked on that page (to the README.DAT) it looks like it's going to build a 2.4.x kernel module (i.e. *.o) rather than a 2.6.x module (*.ko).

For N800 with OS2008 you can try to get my archive of various modules and try to insmod the drivers/usb/ftdi_sio.ko from it.
http://fanoush.wz.cz/maemo/modules-2...-custom.tar.gz

For N800 with OS2007 it is here

http://fanoush.wz.cz/maemo/4.2007-usbhost-kernel.tar.gz
http://fanoush.wz.cz/maemo/4.2007-us...modules.tar.gz

See also N800 usb-host thread in mailing list for details.

For 770 I currently don't have ftdi_sio.ko but could make one easily if there is a need. However there is usbserial.ko and pl2303.ko in /mnt/initfs/lib/modules/current which should be enough for pl-2303 based usb to serial converters (which are fairly common in various mobile phone cables).

I have added ftdi_sio.ko to http://fanoush.wz.cz/maemo/modules-3.2006.49-2.tar.gz for 770

Yup. I just downloaded and extracted fanoush's modules to my 770. Then ran
Code:
#insmod  drivers/usb/serial/ftdi_sio.ko
I can send and receive data over serial. I have only tested using pyserial but it seems to work perfectly.
