By the way, this is not necessarily true. Many pieces of hardware can be used in normal mode but will fail a firmware update using the same connection for different reasons. Mostly because firmware update modes change the status of the device temporarily and there are often communication checks (so checking the timing of communication) in order to prevent the firmware update from accidentally bricking the device. USB hubs, long USB cables, unpowered hubs are often the culprit. If any of those things are in use, temporarily, for the purpose of doing a firmware update, change that (short usb cable, directly into the computer)
