Hey djb, I was having the same problem as you were and I found a simple solution. Assuming that you have already download the drivers from the Android SDK website proceed with the following step by step instructions:
1) Plug in your device and make sure it is not set on tethering (You will most likely get the information that it has failed to install properly) 1) Click the "Start Button" and type "Device Manager" on the search box. 2) Open the "Device Manager" and locate the ADB icon. (It has a yellow button on it). 3) Right Click on it and select "Update Driver Software". 4) Select the "Browse Option" not Automatic. 5) Select "Let me pick from a list of device drivers on my computer". 6) Select "Show All Devices". 7) Select "Have Disk..." 8) Select "Browse..." 9) Look up for the <google-usb_driver> tab, select the "android_winusb.inf" and press "Open" 10) Select the "OK" button. At this point it will warn you that the driver is not signed, please proceed to ignore it by selecting the "Android ADB Interface" and clicking "Next". Ignore the following Warning(s) and continuing to installing the driver. 12) And...EUREKA! You may now close the Device Manager and commence to test your applications by using your MyTouch4G! I hope it works as well as it did for me, best of luck! Sincerely, elmejorpadresito -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
