OK I used system restore to restore the system to the way things were before my mistake with PDANet. I plugged in my coby and the Found New Hardware wizard popped up. The generic Android device is once again listed under 'Other Devices' in the device manager. I went through "Install from a list or specific location" -> "Don't search. I will choose the driver to install." -> Double-click Show All Devices and a long list of manufacturers and their models comes up. But Google Inc is not among the list. What installer should have added that entry? It's not the sort of thing that would come with windows. I installed the Android SDK including the Google USB drivers. So I guess it wasn't from that. I tried "have disk" and navigating to the cobyADB directory but it wants to see .inf files, not dll's.
