+See converter/usb_usb/README.
Restriction and Bug
-------------------
-Not supported/confirmed yet.
- Hub, suspend, keyboard LED
-
-Switching power on VBUS:
- To power reset device.
- http://www.circuitsathome.com/camera-control/simulating-cable-disconnect-on-usb-host-shield-2-0
- This is needed for a device which are not initilized with 'USB Bus Reset'(long SE0)
-
-Can't bus-reset a keyboard which already attached on bus properly.
- Slow start up of Leonardo's bootloader causes this?
- Need to unplug/plug a keyboard after firmware starts up.
- MAX3421E doesn't work SAMPLEBUS well to know whether device connected or not.
-
-Keyboard with other endpoints than boot keyboard may go wrong.
- On my keyboard with mouse key the converter locks up when using mouse key function.
+Not supported/confirmed yet: Suspend
Can't compile on Windows filesystem.
On Linux no problem.
Windows doesn't know difference between common/print.h and arduino/Print.h.
- Change file name common/print.h to console.h ?
+ Change file name common/print.h to something?

+ * Udp.cpp: Library to send/receive UDP packets.
+ *
+ * NOTE: UDP is fast, but has some important limitations (thanks to Warren Gray for mentioning these)
+ * 1) UDP does not guarantee the order in which assembled UDP packets are received. This
+ * might not happen often in practice, but in larger network topologies, a UDP
+ * packet can be received out of sequence.
+ * 2) UDP does not guard against lost packets - so packets *can* disappear without the sender being
+ * aware of it. Again, this may not be a concern in practice on small local networks.
+ * For more information, see http://www.cafeaulait.org/course/week12/35.html
