I've had all sorts of problems getting ADB to run in the past so I generally know how to trouble shoot this but now I can't get windows 7 to recognize or install the USB driver when I plug it in. It was running fine until I flashed a new Cyanogen ROM but since reverted back to a version I know was working.
The SDK is up to date, and it has the Google USB driver installed, I've uninstalled it and reinstalled it as administrator. When I plug in my phone via USB it tries to install 4 android devices which all fail. If I click on a device and try to locate the drivers manually and point it to the SDK dir it just immediately says windows can't find a driver.
Also I can connect to the device using WIFI ADB, and can also mount the SD card to my comp via USB.
