Title:
  056a:0302 Trusty Tahr, kernel 3.13: automatic load of wacom.ko driver
  cause a "hard" kernel panic

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I have just upgraded to 14.04 from 13.10.

  I have a wacom cth-480  touch+pen tablet, which was not recognized on
  13.10 (kernel 3.11). With the stock kernel from 14.04, I have an
  immediate kernel panic as soon as I plug in the tablet to the laptop.

  The system is a asus 1005PE (32 bit install), Xubuntu, up-to date:
  Linux asus-romano 3.13.0-24-generic #46-Ubuntu SMP Thu Apr 10 19:08:14
  UTC 2014 i686 i686 i686 GNU/Linux

  The really strange thing is that if I manually load the driver with
  `sudo modprobe wacom` *before* pluggin the tablet in, then the tablet
  is recognized and works ok:

  SYS: Apr 21 15:15:47 asus-romano kernel: [  265.664161] usbcore: registered new interface driver wacom

  SYS: Apr 21 15:15:52 asus-romano mtp-probe: bus: 2, device: 2 was not an MTP device

  A screenshot of the kernel panic is added. I can reproduce it at will.
