Yes, windows update does search the internet for drivers. The thing I am seeing is the cerberus is not even recognized as a usb device. My Spider and Hydra seem to work fine. I am almost thinking that the Cerberus is fried, the only thing that gives me hope that it isn’t is the fact that with ST mode it boots and I can apparently do firmware updates.
You are doing everything correctly and this should not be happening. It seems that the firmware is getting corrupted at some point either before or during the installation; I would suspect the latter because you tried two different ones with the same result. Perhaps your only option right now is to get an RMA for the board.
I have 3 cerberus. One cerberus is now with the same problem. I can replace the TinyBooter (with the boot) but MFDeploy cannot find the cerberus. The description USB is “Unknown Device” in Windows.
So this card is fried ?
Try different USB port.
