 Bigger Bigger  Smaller Smaller  Reset Reset

Hi,

I'm trying to set up an USB-connection between my N810 (running DIABLO_5.2008.43-7) and my Arduino Leonardo to get its serial output.

When I' am using an USB-OTG cable the arduino powers up. But there is no /dev/ttyACM created.
The problem seems to be the kernel module - older arduinos used the FTDI chip and there seems to be a module already for this http://forums.internettablettalk.com/showthread.php?t=88618.
But the Arduino Leonardo doesn't use the FTDI anymore.
I tried the kernel modules attached to this instruction for the UNO R3 which seemed also not using the FTDI chip anymore: http://ascaniocolonna.com/fun/nokia-n810-arduino-setup/

It seems that I need to use the cdc-acm.ko and usbserial.ko usb module/driver.
But when I load the modules via insmod and connect my leonardo I get the following dmesg output:

So it says "[ 6010.460937] cdc_acm 1-1:1.0: ttyACM0: USB ACM device" but there's no /dev/ttyACM* created.

Is there anyone dealing with the same problems or someone who can help me getting this setup to run?
It would be great to use my N810 as an wireless webserver/programmer for the arduino smiley

Well, didn't found an exact solution to my problem, but as a workaround I'm now using an pl2303 based USB to RS232 adapter (<5€) and a MAX232 level converter to connect the N810 USB port to the Serial1 port of the Ardunio Leonardo. The pl2303 is supported by the additional kernel module which is available precombiled via the link of my previous post. Just did an additional
Code:
insmod /lib/modules/2.6.21-omap1/kernel/drivers/usb/serial/pl2303.ko
and now it works fine to transfer some measured data to a file via
Code:
cat /dev/ttyUSB0 > fileXY.csv
so I'm happy smiley

greetz, skunkjoe
