|Second delivered version
Deliverd since June 08
If you update an 'older' V1.0/V1.2 hardware - sold till approx.
beginning-midth 2010 - then you also need the hardware modification
described here USB64_tec_hw_mod2.pdf otherwise your USB64 will no longer connect to USB correctly!
Third delivered version - also the hardware has some modifications
Deliverd since approx.march 2010
(1) 1.2 This update is only for older devices, which were deliverd with JP13,JP12,JP15 ( please look into the current manual for the newer USB64 V1.3 f.e. page 7,15 to see the difference and identify your USB64 type).
You should update only older devices ( without the modifications described in the manual on the pages 7,15) with the firmware V1.2.
Newer V1.3 devices still have the V1.3 firmware and V1.2 is included in V1.3 , so an update with V1.2 on V1.3 devices would not make much sense.
For V1.3 you need a little hardware modification.
That is because a free input pin of the processor is now used by the firmware to test and recognized, if a usb connector is attached to the board or not ( so that it can activate it's usb drivers only if needed - which optimizes performance and usb arbitration ) ...
This is done at the position where V1.0/V1.2 USB64 hardware has it’s jumpers JP12/JP15.
