Hi everyone. I'm trying to connect my arduino (exaclty funduino uno r3, but it's same as original arduino) with my samsung i9000 via usb host mode. The problem is that my phone doesn't support this officialy, but i found unofficial drivers developed by xda community. Now i have installed cyanogenmod 10 and semaphore kernel 2.6.6 (with built-in usb host drivers). My DIY usb-y cable works fine (i9000 doesn't support power supply), and mounting storage devices in usb host controller app too, but before all i have to turn on "disable charger" option. Now it's time for arduino - it's recognized correctly in controller app. There are logs from adb shell:

Next i tried to receive serial data from arduino, my arduino code:
void setup() {
Serial.begin(9600);
}
// the loop routine runs over and over again forever:
void loop() {
Serial.println("Hello");
delay(1000); // delay in between reads for stability
}
In first attempt after "cat /dev/ttyACM0" command i get I/O error, but led start blinking, log:
<4>[ 1604.376792] tty_port_close_start: tty->count = 1 port count = 0.
In second there's only silence, nothing happened - led still blinking. After crtl+c i get tone of logs like this:
<3>[ 2015.202781] otg_err: in s5pc110_otghcd_urb_dequeue()::00508
<3>[ 2015.203963] => fail to cancel_transfer()
<7>[ 2015.211899] usb 1-1: hcd_unlink_urb e5721400 fail -1
This method work fine on linux.
Anyone have some advice?
