These days I am working on PayPal, they limited my account…Hope this thing be solved soon.
Someone said I will cost 20% on develop and 80% on other mess things, now I know he is absolutely right 😀
This is my USB test platform, looks like I make a mistake on the first version of dock, USB can not work, so I have to make this ugly thing 😀 Lucky me, everything works normal.  in /dev/ the sda node appears, next, I need to mount it to system, then I can read/write the USB disk. But my USB disk is ExFAT format, and I did not compile that support to VoCore firmware, so need some more work. Time for lunch. 🙂
