24 * usbprog is a free programming adapter. You can easily install
25 * different firmware versions from an "online pool" over USB.
26 * The adapter can be used for programming and debugging AVR and ARM
27 * processors, as USB to RS232 converter, as JTAG interface or as
28 * simple I/O interface (5 lines).
