New Revision: 1182

Modified:
   firmware/fuxusb/trunk/src/usb_enum.c
Log:
* Bug : usb_enum.c -> set_interface
  When the interface 3 (HID interface) is set, the banks and the eps have to be
  cleared. Otherwise, the EPs are corrupted. The result is that the command is
  often ignored.
  This problem occurs especially with tuxup, when the dongle has to be flashed.
  Tuxup uses the set_interface function, even if the interface is already set.

  I've also added code to reset the audio EPs when the actives interfaces
  (alternates interfaces 1) are set.
