I tried to copy files from my Android phone using the gvfs fuse mount created for it. However, while I could copy directories, I always got "Operation not supported" when trying to copy files. If file read and copy operations are going to fail, then the mount is nearly useless and shouldn't be exposed via FUSE. Example output: cp: no se puede abrir «/run/user/1000/gvfs/mtp:host=%5Busb%3A004%2C008%5D/Phone/Android/data/com.google.android.apps.maps/cache/cache_vts_GMM.m» para lectura: Operation not supported cp: no se puede abrir «/run/user/1000/gvfs/mtp:host=%5Busb%3A004%2C008%5D/Phone/Android/data/com.google.android.apps.maps/cache/cache_vts_tran_base_GMM.m» para lectura: Operation not supported cp: no se puede abrir «/run/user/1000/gvfs/mtp:host=%5Busb%3A004%2C008%5D/Phone/Android/data/com.google.android.apps.maps/cache/cache_its.m» para lectura: Operation not supported
