Hello,

Please try the following steps:

1. Change your USB cable (There might be some losse connections ?!?)
2. Reinstall Arduino IDE and Xadow Driver (See here)
3.Only connect Xadow main board without any other boards to PC.

Thanks and Warm Regards

Thanks for help
i had load a incorrect sketch - see bottom
then i had the same problem
- but under win 7 not under linux
in device manager
i saw for a short time the virtual xadow com port
the a refresh
and the message : unknown usb device

the way out
disconnect mainboard from usbport
start arduino
load sketch ledblink or another sketch

--now be fast--
connect mainboard on usbport
click tools
click port
when you fast enough you see : seeduino xadow port (COMx)
click port this port

start upload the sketch
und when message uploading appears press reset button
- then mainboard make a softreset -
now the led must blink

if not
try again an upload
you can do this more the one times

---------------------------------
i have found the killer sketch
i tries serval times - works good

#include <Wire.h>
#include "xadow.h"

void setup()
{
DDRB |= 0x06;
}

void loop()
{
//turn on the buzzer
PORTB |= 0x06;
delay(1000);
//turn off the buzzer
PORTB &= ~(0x06);
delay(1000);

Xadow.pwrDown(1000); // sleep for 1000ms
Xadow.wakeUp();

}
