I can not get a debug connection to my i5800. If I install Samsung's Kies software (which includes their driver), the phone shows up correctly in the device manager but I can not find it using the adb tool that comes with the android SDK. The drivers that come with the android SDK won't even install. Of course, I have USB debugging activated on the phone. Does USB debugging work for anyone? What driver did you use? Also, if I disable USB debugging and set the phone to "Ask what to do on USB connection" it does not ask when I connect it. So it could actually be a problem with the phone as well. Any suggestions?
