I have noticed some issues with the USB adapters not resetting the com ports or reporting the com port as busy which will not allow the receiver to communicate. Look at the steps posted above. In the Device manager where you see the com port you should be able to right click and goto properties. In thoses setting (I have Vista) I can goto an advanced setting to see if the adapter is busy or idle. If busy, I have a test option and it resets it. If idle and its not working I unplug the cable from my computer and retry again. Somtimes I have to plug and unplug a couple of times.
