My MI4 died after the latest Win10 update. It has been working until october, but was rendered useless after the fall update. I tried every trick in the book, but when reinstalling the good old vista64-drivers, the device shows up as “normal” in the playback devices, but when I check the devicemanager, it “requires further installation” and is “not migrated”. I really hope that Steinberg will provide an updated driver for this, because it’s really not good for anyone if we have to throw away our MI4s and invest in a new device, since it’s actually a great soundcard. The environment cries.
