+ * The routine usb_set_maxpacket_ep() is extracted from the loop of routine
  * usb_set_maxpacket(), because the optimizer of GCC 4.x chokes on this routine
  * when it is inlined in 1 single routine. What happens is that the register r3
  * is used as loop-count 'i', but gets overwritten later on.
  * This is clearly a compiler bug, but it is easier to workaround it here than
  * to update the compiler (Occurs with at least several GCC 4.{1,2},x
  * CodeSourcery compilers like e.g. 2007q3, 2008q1, 2008q3 lite editions on ARM)
