Problem is still present at Ubuntu 15.10 (Wily) - i know it's not released yet, but soon!
Tried to edit /etc/udev/rules.d/69-libmtp.rules added the line for my Asus Zenpad, but there was no effect. dmesg says: [ 323.054437] usb 1-3: new high-speed USB device number 3 using xhci_hcd [ 323.184081] usb 1-3: New USB device found, idVendor=0b05, idProduct=600f [ 323.184091] usb 1-3: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 323.184096] usb 1-3: Product: Android [ 323.184100] usb 1-3: Manufacturer: Android [ 323.184105] usb 1-3: SerialNumber: F8NPFX007863 [ 343.415915] usb 1-3: reset high-speed USB device number 3 using xhci_hcd [ 348.860781] usb 1-3: usbfs: process 2251 (pool) did not claim interface 0 before use lsusb: Bus 001 Device 003: ID 0b05:600f ASUSTek Computer, Inc. mtp-detect: libmtp version: 1.1.9 Listing raw device(s) Device 0 (VID=0b05 and PID=600f) is UNKNOWN.

I created the file /etc/udev/rules.d/51-android.rules like it was mentioned in an other post. Then i switched on USB-Debugging and restarted the computer (to be sure ;-) ) dmesg: [ 42.975528] usb 1-3: new high-speed USB device number 3 using xhci_hcd [ 43.105193] usb 1-3: New USB device found, idVendor=0b05, idProduct=601f [ 43.105202] usb 1-3: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 43.105208] usb 1-3: Product: Android [ 43.105212] usb 1-3: Manufacturer: Android [ 43.105216] usb 1-3: SerialNumber: F8NPFX007863 mtp-detect: libmtp version: 1.1.9 Listing raw device(s) Device 0 (VID=0b05 and PID=601f) is UNKNOWN.
