I cannot flash the t400. Using two different test units. Proper firmware and even hello world scripts.

Set to flash as Lilypad Arduino USB.

Start upload... the device powers off and does not power back on again. Errors on missing USB port.

If I manually restart the device, it boots immediately into the LCD interface ( aka runs the sketch ), it does not update, and the arduino software declares upload complete... because it just cannot face the harsh reality that the upload is NOT complete and may never be.

Hold down the power button while flashing. This will keep the PWR_EN pin high and keep the processor in.
