Windows doesn't detect Nexus S I recently switched from Linux to Windows 8 consumer preview. I have installed the latest android SDK including the Google USB driver. I connect my Nexus S to the laptop, the phone goes into USB debugging mode. But Eclipse doesn't detect it. if I do >adb devices, the phone doesn't show up. Please help!
Try this: find the .android folder in your home directory, and replace the adb_usb.ini file with this one. this tells your computer to let adb work with a load of different usb devices. You may need to restart ADB via the command line:

adb kill-server
adb start-server


and now adb should show you your device

adb devices
