+ * 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)
+ *
+ * NOTE: Similar behaviour was observed with GCC4.6 on ARMv5.
