MTP suddenly stopped working on my desktop running Windows 10 Pro N and I can't transfer files between my android devices through USB. I already installed the Media Feature Pack for windows before, I reinstalled it but it didn't solve the problem.
In windows explorer there is just a grayed out USB-Drive and I can't do anything with it.
In the device manager the MTP device is in the 'Other devices' category with a yellow exclamation mark. I tried deleting the driver and updating the driver by selecting 'MTP device' from the driver list but it didn't help.
I tried it with a Oneplus One and a Nexus 7 (2012) and neither of them worked. I also tried it with a different USB cable. Adb works fine and MTP works on my laptop, which also runs Windows 10 Pro N with the Media Feature Pack update.
Any help would be appreciated.
