I have just got my Dell Streak and updated it to Android 2.2.
I got Eclipse setup with Android etc and have used it with other android phones.
However when I plug in my dell streak and turn on USB debugging. Nothing comes up in Eclipse.
Is it because its picked up the device as a Dell Streak and not installed a ADB driver?
It seems you are missing the driver for dell streak. Check out the android developer site for links to different OEM drivers http://developer.android.com/sdk/oem-usb.html
